Can't send mails (POP account/SMTP)

Okay, this issue has been posted before, but none of the difficulties or possible solutions described seemed to match my problem, which is:
When I click the "send" button in Mail, it simply does *nothing at all*. It doesn't even seem to try to do anything, let alone give me an error message.
I used to have an iBook with OS X 10.2, and Mail has always worked perfectly fine on that system. Now I just bought a new iBook with Tiger installed. I first updated to 10.4.6, then transferred all my data, including my mail settings and mailboxes, to the new computer, with the result that I can receive mail, but I can't send e-mails. I tried deleting my account and creating a new one, but that didn't change anything. I can send e-mails through my provider's webmail system, so the SMTP server isn't broken down; anyway, my husband is using the same server, and he can send mails, so I guess it's somehow an issue with my computer and not with the provider. My account settings are definitely correct. I can "ping" the mail server. I tried deactivating my firewall, but that wasn't the solution either.
What else could I try? My outgoing mail server is an ordinary port 25 password-protected SMTP server. I strongly suspect that the problem is with 10.4.6, but I'm not exactly keen on the hassle of downgrading my system back to 10.4.5 or whatever... Or is there an easy way to do that?
Any other ideas? I'd be really grateful. Not being able to send mails *****.

Hi Johanna,
Have you tried the Activity Viewer? (Window > Activity Viewer in the menu.) Try sending an email, and see if any error message appears in the Activity Viewer window after you click "Send".

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.....

I can not delete mail pop account in iphone 4S

Hello
I have set POP mail account earlier but I do not want this account now. I am trying to delete the accont but there is not any button delete account as IMAP mail account have. What is happening? How can I delete the account?

There isn't any reason this POP account should not be able to be deleted. Are there any Restrictions set on the phone? Who is the provider of this email account? I'll assume that you are trying to delete it from Settings>Mail, Contacts, Calendars? You go to the Mail section, select the account in question, scroll to the bottom of the account page and select delete. However, you are saying when you do this, the Delete Account button does not exist, correct?
The next troubleshooting step after a reset is a restore from backup. You can try that if you like. What happens if you go into the account and toggle the on off button at the top of the 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:
Properties props=new Properties();
props.put("smtp","smtp.163.com");
props.put("auth","true");
MailUser mu=new MailUser("username","password");
javax.mail.Session session=javax.mail.Session.getDefaultInstance(props,mu);
public class MailUser extends Authenticator
String username;
String password;
public MailUser(String us,String ps)
this.username=us;
this.password=ps;
}

Properties props = System.getProperties();
props.put("mail.smtp.host", "hiart.co.kr");
props.put("mail.smtp.auth","true");//auth module....
session = Session.getDefaultInstance(props,null);
Date date = new Date();
msg = new MimeMessage(session);
System.out.println(from);
msg.setFrom(new InternetAddress(from+"@hiart.co.kr"));

Can't send mail - server properly configured and up

I'm unable to send mail. Here's roughly the sequence of events that
got me where I am:
1) Connect through a firewall using VPN (the Cisco VPN client)
over the wireless interface
2) Compose a message, and click 'Send'
3) The server is down, so I get the "Can't send e-mail" pop-up
dialog
4) Click 'Try later'
5) Reconnect later while the server is up, and try to send
6) Still see the "Can't send" pop-up
Steps 3) and 4) happened a lot. In particular, turning on the
wireless interface in order to connect over VPN causes Mail to try
(and fail) to connect to the server.
The server is up; I can reach it with "telnet <server> 25".
Moreover, Mail's own "Connection Doctor" says it's able to connect
to the server.
This configuration worked until the sequence of events described above,
and nothing on the server side has changed since.
I've tried everything I can think of to get Mail back in a working state.
Notably I've deleted the contents of "Outbox", quit Mail, and then restarted.
I've also deleted and re-created the server configuration, without success.

Two additional data points:
1) I found a mail server I could use from outside the firewall.
When I added that server, and closed the VPN session, Mail was
(finally!) able to send. (But see below why you shouldn't rush
to blame VPN).
2) When there are two mail servers configured in preferences, the
"Can't send mail" pop-up gives you the list of choices. If you
select an alternate server from the list, the "Try selected
server" button ought to try the new server. Instead, the
pop-up reappears, still complaining about the old server.
As for why I'm not prepared to blame (only) the VPN:
* Note that the server is perfectly accessible; telnet works,
and Mail's Connection Doctor says the server is up.
* Point 2) above indicates some problem in Mail with the logic
for retrying access to the failed server.

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.

CANNOT SEND MAIL FROM .MAC SMTP ACCOUNT

Hello everyone--
I can receive mail from my .mac account and have done extensive troubleshooting including:
1. Changing ports from 25 to 587
2. Deleting and re-installing mailbox
3. Reading a hosts of topics
4. I have the serving settings with SSL unchecked
...but this still giving me the same trouble. I cannot send out because my email address keeps getting rejected.
Any suggestions? Thanks!

Are you also accessing an email account and SMTP server in Mail that is provided by your ISP used for connecting to the internet?
If so, can you send mail with this account and SMTP server?
If the answer is yes to both questions, select/use your ISP's SMTP server to send mail with your .Mac account which is invisible to all recipients.
Most, if not all ISPs now block the use of SMTP servers outside of their network on Port 25. Some ISPs allow the use of an authenticated SMTP server only (such as the .Mac SMTP server) that is outside of their network on Port 25 but some block its use regardless.
Changing the Port for the SMTP server that is outside of the ISP's network from 25 to 587 usually resolves it but sometimes not depending on the ISP's restriction.
Have you contacted your ISP regarding their restrictions and/or requirements when using an SMTP server that is outside of their network or not provided by them?
Using your ISP's SMTP server to send mail with your .Mac account should work and it may be required regardless.

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

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.

Can receive but can't send mail via BT Yahoo SMTP server port 995

Suddenly I can't send mail from my BT/Yahoo account but can still receive mail. The message that i get is that it was rejected by the server. I have not changed the server - it is still SMTP via port 995, using SSL. Help!! Why should this have ocurred out of the blue and what do I do?

Hi Dancing Brave,
Thanks for visiting Apple Support Communities.
I recommend starting with the steps in this article if you are not able to send mail:

User "null" with comcast SMTP, can't send mail with Mail 3.1

it was kind of off and on, now seems permanent. When sending mail via comcast SMTP, the following error is returned: P*lease enter the password for user “(null)” on SMTP server “smtp.comcast.net”*
The mystery is how user got to be "null". Deleting the account and redoing it doesn't help. Changing port to 25 and 587 don't work. I get mail fine, just can't send. Yes, my user name is actually filled in on the accounts page. Gmail works fine...
Thanks

wierd...
blanked out my username, but Mail insists on having a username. So on a lark I put back my username with the @comcast.net domain and it worked (one test message anyway). I left the password filled in 'cuz I hate having to fill my password in every time.
So thanks for joggling the idea bank!

Can't send mail out of my iPad and iPhone using my office work mail account.

I can't send mails out of my work mail account on IPad or iPhone. I usually get error message that the server does not accept relay messages. I only get this problem on IOS devices only but on other platform I don't . Please can anyone help fix this?

After Leopard upgrade can't send mail in Apple Mail with dot mac account.

Just upgraded to Leopard and now I can't send mail through Apple Mail. Checked smtp and that's OK. How do I check what ports are open? That may be the problem. I looked at the Apple trouble shooting page and did everything there except the port check.
Any other suggestions?
Thanks,
Lou

Fixed my own problem. I put in the SMTP address but didn't save. Once I saved it worked.

Postfix/smtp[8437] Operation timed out can't send mail to 1 address

server 10.4.5 running mail, filesharing and website.
The mail server has been up for months working fawlessly. We have one address (domain) where we can't send mail, and users at that address can't send us mail.
All other mail functions on both ends seem to be functioning fine.
They seem to be running exchange as a mail server, but i don't have other details from their side. DNS/MX records all look like you would expect.
This has me stumped.
i turned debug level loging on and got the following smtp message written to the log when i tried to mail to an address at that domain.
Feb 23 20:45:10 fileserver postfix/smtp[8437]: 775401AFD61: to=<[email protected]>, relay=none, delay=31, status=deferred (connect to anhc-mail.anhc.org[24.237.2.213]: Operation timed out)

Yes, good luck to them.
relay=none
doesn't look so good.
Of course, a successful outgoing message should look something more like:
Apr 8 11:41:05 server postfix/smtp[2300]: F1D4D3B8A27: to=<[email protected]>, relay=mail.someobfuscatedserver.com[6x.20x.148.1x6], delay=5, status=sent (250 2.0.0 k38FYfDS023848 Message accepted for delivery)
I take it you can send to any/all other mail addresses (servers) ?
Here's a thought:
Some time ago, I had to edit the helo_checks config of postfix, for a windows mailserver because their AntiVirus was horribly mangling their outgoing mail, helo-ing as <fix-your-dns>.local
Point being that .local anything is not a viable tld for anything in the public realm, and certainly won't work with the rest of the world in terms of DNS.
That might be the work of Norton's break-it-for-you addon for Windows Exchange mailservers, not sure.
Please post the output of:
postconf -n
on your server,
and the mail.log file content when they try to send you an email (confirm via telephone and watch for it).

I had an imap account in my iPad and my iPhone 4. They worked just fine till about Christmas. They act like they are checking the mail and it shows there is mail to come in, but it just goes back to saying checking mail. Can't send mail either.

Update to above question:
Hello All,
To anyone with the same problem described above, on THEIR iPad (if it is running iOS 7.0.2):
Go to Settings; Mail, Contacts, Calendars; DELETE your *******@btinternet.com e-mail account, that you originally set up either using 'Other', or the 'BT' option which I am sure was in the list previous to the iOS 7 update.
Then ADD a NEW account choosing YAHOO from the list of options. DO NOT USE 'OTHER'.
Enter the correct details just as you (almost certainly) had already done in your previous attempts using 'other'.
When you see the 'verifying......' and 'the blue ticks' you should be able to exit settings and open your mail app and then receive all your 'old' e-mails again, AND be able to SEND as well.
All my 'old' e-mails, were NOT found in the 'old e-mail' folder though. THEY are still in my inbox.
So this fix worked for me.
After I deleted my account from 'OTHER' and put it in Yahoo, I like other people also ended up with more folders.
I hope this works for you on YOUR Apple devices.
Bob
