Can't Send Mail: Authentication Required.

Hi All,
If anyone can help me with this, it will be most appreciated.
Mail Version 2.1 (752/752.2)
I can receive e-mail, no Problem.
I can't send e-mail... I keep getting this message: Cannot send message using the server outgoing. verizon.net
The server response was: 5.7.1 Authentication Required.
I've set all my mail accounts as they should be. I've used the Connection Doctor in the Window menu and all connections incoming and outgoing are ok.
Thanks

Go to Mail > Preferences > Accounts and under the Account information tab for your .Mac account preferences at the SMTP server selection, select the Server Settings button below.
Enter 587 in place of 25 in the Server Port field and when finished, select OK to save the changed setting.
All other settings for .Mac's SMTP server should be as follows:
Outgoing Mail Server: smtp.mac.com
Use Secure Sockets Layer (SSL): I have this selected but isn't required.
Authentication: Password
User Name: The portion of your .Mac email address in front of the @ sign only.
Password: Your .Mac account password. The same password used to check for new messages or to login to your .Mac account via webmail access using a browser.
If changing the Server Port from 25 to 587 for .Mac's SMTP server does not work, are you accessing any other email accounts and SMTP servers with Mail and if so, are you able to send messages with any other accounts with Mail while connected to the internet at this hotel?
You should also check with the hotel's front desk or the hotel's internet service provider regarding their required settings for using an SMTP server that is outside of their network.
If you are unable to use the Mail application for sending messages, you will be forced to use webmail access to do so which is sometimes required and the benefit and primary reason for webmail access with an email account.

I can't send mail to the site that required Authenticator

How can I send mail to the smtp site that required Authenticator,If th smtp site doesn't require Authenticator ,I can send mail.
My program:

Can't Send Mail Since Updating To Leopard

I can get, but can't send mail using Apple mail with my local server running on port 110. Never had a problem with Tiger. Thunderbird works fine. My .mac account also works with both Apple mail and Thunderbird.
Any feedback would be appreciated.

Hello, and welcome to the Discussions.
Most likely your local SMTP requires no separate Authentication, but in upgrading to Leopard, the settings have been changed. In Mail Preferences/Accounts/Account Information, click on the arrows beside the name of the smtp, and choose Edit Servers. Then under the Advanced Tab, check that the Port is 25, and choose Authentication of None, and without any entries for Username or Password. It should now work, but if you have knowledge that the SMTP should somehow be separately authenticated, tell who the provider of this SMTP is?

Can't send mail on other networks

We have been touring the country for two months now and find we often can't send mail (using Mail) on wireless networks in hotels and it happens when we are visiting friends as well. We can always receive mail, however. It's frustrating as we're keeping friends and family posted on our trip's progress. Any ideas??? We can send e-mail through our .mac account on the Apple web site but sending photos doesn't work as well.
Some hotel's systems work just fine.

Hello Frederick.
Most, if not all ISPs now block the use of SMTP servers that are outside of their network (or not provided by the ISP) on Port 25 which is the standard port used by SMTP servers.
Some ISPs allow the use of an authenticated SMTP server only (such as the .Mac SMTP server) on Port 25 but some block its use regardless.
These restrictions are in place as part of an overall effort to prevent spam emanating from the ISP's domain.
Some free wireless networks (at hotels) will allow using an SMTP server that is outside of their network on Port 25 if the SMTP server is not authenticated (and why is a good question if so) and in that situation, selecting None for SMTP authentication should work.
Basically, you need to check with the hotel or the hotel's internet service provider regarding their required settings for using an SMTP server that is outside of their network.
When visiting friends and connecting to the internet via their ISP, you can try the following:
Go to Mail > Preferences > Accounts and under the Account Information tab for your .Mac account preferences at the SMTP server selection, select the Server Settings button below.
Enter 587 in place of 25 in the Server Port field and when finished, select OK to save the changed setting.
If this doesn't allow you to send mail with your .Mac account and SMTP server, you can try entering and using the SMTP server provided by your friend's ISP to send mail with your .Mac account which is invisible to all recipients.
When accessing free wireless networks at hotels, you can try using 587 for the Server Port for the .Mac SMTP server but as previously provided, you need to check with the hotel or the hotel's ISP to determine the required settings for using an SMTP server that is outside of their network.
If using 587 for the SMTP Server Port works, you should be able to keep this setting for the .Mac SMTP server when returning home. I use Port 587 for the .Mac SMTP server when connected to my ISP at home and I've also used it successfully when connected to a friend's wireless network via a different ISP.

Can't send mail, get message: the smtp server rejected the password. I tried lock and unlock keychain. I tried unlock captcha. Gmail works okay, it is Mail that does not. Help!! :(

Hi
You need to check with your ISP whether or not the send mail server (SMTP) requires a password. Some do, but many do not. When you know the correct password to send mail, then you need to tell Mail as follows:
Mail menu > Preferences > Accounts > Select the account
Click on the Outgoing Mail Server (SMTP) combo box, and select Edit SMTP Server List...
In the Account Information tab put the server name
In the Advanced Tab, set up the authentication information from your ISP.
Good luck

Can't send mail- password rejected

I just got a new MacBook and after setting up Mail, I can receive emails but I can't send them. I get an error message that reads "The SMTP server “smtpauth.earthlink.net” rejected the password. Please re-enter your password, or cancel." But then when I re-enter the password, it still rejects it. I've read every troubleshooting thing I can find, but nothing will solve this problem. I've checked the outgoing mail server, my user name and password and everything is correct. And I still can't send mail. HELP!

Can Not Send Mail- what's going on?

Can download mail but can not send mail. With parallels on and xp pro I can easily set up outlook to send and receive mail. But no! The great Apple which is supposed to be easy can not send an email with the same settings. So, back to Windows to do what should be easy on a mac. I think that perhaps the new Safari or something messed this up.

If you'd like to approach the problem as something you don't understand, and also something that can be fixed, then you'll probably be able to set up your email account.
You say you have emails in the Outbox. I'd move them to another folder you create or delete them. In past experience, emails contain header information that includes mail server information, and sometimes they will never send (especially with Outlook Express), even if you get the account to work. You can try sending them again, once you get the account working.
Next, you need to make sure that you are sending the emails from a machine that is connected directly to RoadRunner's network. They may not work as a relay if you connect from another ISP. It's a port 25 problem that is common these days.
Now for the problem. If you are receiving emails properly, then the POP server information is correct. The mail program is designed to set up to some default settings that work with many servers, and during the process it will try to validate the settings you supply. This can take awhile, and can come up with a failure, due to a wrong assumption. Your email program is assuming that the email server requires authentication. This has been a problem with the RoadRunner system for years. Apparently, some windows email clients do not work the same way, go figure. They seem to have their own problems.
Many people have reported successfully setting up an account with RoadRunner, after first making sure they have the right SMTP server address. It can be different for different parts of the country.
After the email account is set up, and is failing to work, people go into the Mail/Preferences/Accounts/Account Information/Outgoing Mail SMTP Server - Click on the dropdown button - Choose "Edit Server List" - Advanced - Change Authentication to "None"
Here is a related thread with stories of success with RoadRunner: http://discussions.apple.com/thread.jspa?messageID=9128382&
After the changes, I'd quit and relaunch Mail. Not required, but good troubleshooting practice. Since there are no emails in the Outgoing Mailbox, create a short message and try to send.
I have different problems with different companies for both Mac's and Windows machines. The ISP always blames the OS, especially Leopard and Vista (since they work with more intelligent/advanced (maybe) settings. Besides the Authentication issue that pops up with some servers, there's also the occasional SSL variation and/or login name (sometimes it's the first part of the email address before the @ and sometimes it's the entire email address). Some ISP's block port 25, some do not. All of these settings can vary with each ISP, and can change on a whim (especially the port 25 problem), with working accounts going dark because of security changes at the ISP. Telephone Tech support at the ISP is often unaware of any changes in their system because they are not in the IT loop at the company and some will just go into "idiot" mode when you mention Macintosh. The first level support people are using a script on the phone, and their job is to make you go away...
I'm afraid the Great Apple, as you referred to them, is not able or hasn't focused on the ability to automatically set up accounts with every ISP. They appear to have made some assumptions that work with most servers. Who know's, next month the settings or assumptions may work, or Apple may update their setup script to make allowances specific to Time Warner, but since this has been a problem for over 3 years, I wouldn't hold my breath.
Google: leopard mail roadrunner problem = about 96,000 hits of all sorts.
Google: vista email roadrunner problem = about 1,410,000 hits of all sorts.
Google: windows xp email roadrunner problem = 243,000 hits of all sorts.
Looks like Apple's getting it's market share of problems with RoadRunner and Time Warner
My own local DSL is from a company named Centurytel. They are on their 4th email server setup in the last 5 years, and have finally contracted it out to a 3rd party company to administer. I just tell all of my clients to get a Gmail account and get over it. Let's see, a multi-billion dollar company who's reputation and income is based on service... free with 7GB storage, Webmail, POP and IMAP access, specific support for all major mail programs including Apple Mail, and alternate ports that get around ISP blocking. It seems that once you enable POP or Imap access in the webmail settings menu, Apple Mail and Vista seem to know the proper settings to use.
I'd setup the free Gmail account that will work with any ISP you use, before you get really attached to an email account with an ISP that could change as often as competitor's marketing allows. Also, my iPhone supports Gmail out of the box

I can receive mail on my mac account, but I can't send mail. What should I do?

I can receive mail on my mac account, but I can't send mail. What should I do?

Hello, sounds like you haven't switched to iCloud yet, the old dot Mac & MobileMe servers are going away or gone for most already.
Do not delete the old account yet. sign up for an iCloud account if you haven't.
I understand .mac mail will still come through. Do not delete the old account yet.
You cannot use .mac or MobileMe as type of Account, you have to choose IMAP when setting up, otherwise Mail is hard coded to change imap.mail.me.com to mail.me.com & smtp.mail.me.com to smtp.me.com, no matter what you try to enter.
iCloud Mail setup, do not choose .mac or MobileMe as type, but choose IMAP...
On second step where it asks "Description", it has to be a unique name, but you can still use your email address.
IMAP (Incoming Mail Server) information:
• Server name: imap.mail.me.com
• SSL Required: Yes
• Port: 993
• Username: [email protected] (use your @me.com address from your iCloud account)
• Password: Your iCloud password
SMTP (outgoing mail server) information:
• Server name: smtp.mail.me.com
• SSL Required: Yes
• Port: 587
• SMTP Authentication Required: Yes
• Username: [email protected] (use your @me.com address from your iCloud account)
• Password: Your iCloud password
Also, you must upgrade your password to meet the new criteria: 8 characters, including upper and lower case and numbers. If you have an older password that does not meet these criteria, when you try to setup mail on your mac, using all of the IMAP criteria listed above, it will still give a server error message. Go to http://appleid.apple.com then follow directions to change your password, then go back to setting up your mail using the IMAP instructions above.
Thanks to dpepper...

Can't Send Mail - An Updated Report

My ISP is a (relatively) small one, Metrocast. They do not require authentication to log on to the smtp.metrocast.net server. In all iterations of OS X, from public beta to 10.5.7, sending email was instantaneous, or nearly so.
Right after the 10.6 upgrade, it was impossible to send mail. I used the "edit server list - advanced" function to enter my UID and password for the email account (even though it is not required), and I can now send mail - but it takes 60-120 seconds for the mail to go to the server.
Also, it constantly requires a password, even though a) the server DOESN'T require it, and b) the password is entered in Mail preferences.
Something has changed about smtp behavior in 10.6, and I can't seem to get it working right.

Hi
You need to check with your ISP whether or not the send mail server (SMTP) requires a password. Some do, but many do not. When you know the correct password to send mail, then you need to tell Mail as follows:

Can't send mail on iOS 5 devices with iCloud

A long time ago I signed up for a .Mac trial to use that address with iChat. The trial expired, and, as expected, the address continued to work with iChat, though it no longer functioned as an email address. It then came to be my Apple ID. Now, having set that Apple ID up for use with iCloud, my iOS devicess are having trouble sending, and only sending email from my iCloud address. The reason is this: I logged into <username>@mac.com for iCloud (as that's my Apple ID), and everything set up right except the mail address that iOS Mail thinks I have. It thinks the mail address for the iCloud account is <username>@mac.com. When I send mail to <username>@me.com, my iOS devices get it just fine, but when I try to send mail back, it tries to send it from the @mac.com address, and therefore fails as that is not a valid email address.
I've tried to go into the settings and change the email address that it uses for iCLoud, but with no luck. I see a place to change it, but it is grayed out and won't let me select it and bring up a keyboard to change it.
Is there any way to tell it that it assumed the wrong email address for my iCloud? Or is there no way to send iCloud email from my iOS devices?
Thanks in advance!
P.S. I can send mail via iCloud from the web app and from Apple Mail (OS X Lion), but not from iOS devices because of this glitch. I can also send mail from iOS devices using other email accounts (Gmail, Yahoo).

I found a work around that works. Got to Settings...Icloud....account......advanced....outgoing mail server.....
Add an "other" server.
Host Name p01-smtp.mail.me.com
Put in your me.com email address as username and your Apple ID password
SSL is on
Authentication is password
Server port 587
This worked for me.....I will use this until the bug is fixed. (you may need to use p02, p03 etc) Don't make this server your primary. Leave it in "on" status in the other category.
Good luck

Can't send mail... after 4 months of using it

I'm stumped... help me out please.
When i send a mail out, this message pops up, "Error : This Message could not be delivered and will remain in your Outbox until it can be delivered. Sending the message content to the server failed."
So it's still in my mailbox. But then, it shows up in my gmail account and on my blackberry as a sent mail, but the receiver never gets it. Also, i can still send mail from both my blackberry and gmail.com... just not from Apple Mail.
What's going on?

Sometimes an ISP provider blocks one of your incoming
Mail ports and "won't notify you". ( Why? probably it's their protection software )
In my case Comcast blocked my Port 25 and my Outgoing kept bouncing.
Incoming was fine.
Make sure when you change your Port to 587,
You also check "ON" the Secure Sockets Layer box right underneath,
Then change Authentication: to Password
Then enter your name and password
and click OK.
The reps at most of the providers
are useless and won't tell you
the second part of the solution.
It took me 2 days and 4 reps
at Comcast to find this out
and 10 hours of trying to
clean my Mac...
which they will always
blame.
Best of Luck, Tom

Mail can't send mail on home network

I am trying to help a friend who wants to move from Entourage to Mail. He has a MacBook Pro with 10.6.4 installed and his company uses Exchange 2003. He is moving to Mail due to serious calendar and contact syncing issues through Entourage and his iPhone/iCal/Address Book.
I have setup his Mail account to use IMAP with the Exchange Server. He can receive mail this way, but he cannot send it. Actually he can only send mail when he is at work on his company's network. I have turned off SSL and authentication is through Username and Password.
Funny thing is that Entourage can send and receive mail anywhere he has a connection, but Mail cannot. His company's IT department says that the settings I have in place should work.
How can I further troubleshoot this problem? Is it a server problem? I know 10.6's Mail doesn't support Exchange 2003, but I am not looking for full integration of exchange services.

You may be SOL as you need an SMTP server to send mail and the IT folks may not have it set up. You need a proper SMTP relay to send the mail, period. It doesn't matter what it's called, though convention usually has it set to smtp.example.com. mail.example.com would more often be the address for IMAP or POP connections.
Regarding the inability to send mail from an external network, this is the same problem: You still need an SMTP server to send emails. It's just that the SMTP server on the external network is likely different than the corporate SMTP server. What external network is it, and what is the SMTP server they have set up for machines within their network? Note that many networks don't enable outbound SMTP for random clients due to SPAM reasons.

Can't send Mail on dial up Earthlink?

We have set up a sub account for a grandson on Apple's Mail application. After many problems finally got Mail to receive message but can't send mail.
He gets the message: "his email earthlink.net can not be contaced on port 25, message delivery failed." The primary account works well.
He is on an eMac 10.3 with dial up to earthlink.net

Although I have cable modem service at home with Time Warner (RoadRunner), I've kept an old Earthlink dial-up account for use when traveling in case a high speed wired or wireless connection isn't available which is becoming less common.
If Earthlink is your ISP used for connecting to the internet via dial-up access, I use the following Earthlink SMTP settings for my Earthlink account.
Outgoing Mail Server: smtpauth.earthlink.net
Server Port: 25 (which should work if connecting to the internet via Earthlink dial-up access).
Use Secure Sockets Layer (SSL): Off or not selected.
Authentication: MD5 Challenge-Response
User Name: The entire Earthlink email address.
Password: The account's password - the same password used to check the incoming mail server for new messages.

Can´t send mail on any account

Hi,
Suddenly all of my accounts can´t send mail...
it pops up a window saying mail can´t use this smtp, and it doesn´t matter what I choose for selected server, nothing works.
And if I change the outgoing mail server settings in preferences it does not change in the pop up.
I did not change anything.
I have tried to start new account but nothing works.

Gunz,
For your .mac account, if you are using the smtp.mac.com as the Outgoing Server, change the Port to be Port 587, and test. Although you are using many different venues, more and more ISPs are blocking Port 25 for all but their own SMTP. Are the other accounts unrelated to your ISP? If so, their SMTP may need to be presented either on Port 587, or still another.
If you are having a problem with the SMTP provided by your ISP, then a change in policy may have been accompanied by a new name for their SMTP, or a new Authentication protocol.
More info, please, but first test with Port 587 and the smtp.mac.com.

Can't Send Mail Via HughesNet SMTP Server

After installing 10.5 I find that I can receive mail from my ISP (HughesNet) but I can't send mail through the smtp server. I've tried every setting possible and even duplicated the settings off my wife's 10.4.10 iMac and I still can't send mail. All I see is that the smtp service is "Offline."
Fortunately, I have a .Mac account so I can send mail using that smtp server. But I'd like to be abel to use my HughesNet server.
Does anyone have any suggestions?

My mom uses RoadRunner by Time Warner. She was able to receive email using Leopard and Mail but not send. SMTP server was the big problem like everyone else here experienced. We finally were able to get it to work using many ideas here. What we did:
1) Delete com.apple.mail.plist from the User/Library/Preferences folder (BACK UP YOUR EMAIL FIRST)
2) Open Mail and create a new account but disable the automatic set-up feature, put your info in manually.
3) Uncheck " Use only this server" from the outgoing mail
4) Under the Advanced tab on Mail Prefs "port set to 25", Uncheck "SSL" box, and uncheck "Use Authentication"
5) Now hit Create
It took Mail about 20 minutes to contact the SMTP server, but it did and now I can send and receive Mail without any problems on her computer.
Bad Apple...stop criticizing MS and Vista when your own house is not in order yet. Hope this helps someone out there.....
