Cannot send mail (SMTP offline)

I cannot send emails from either of my two email accounts (Hotmail and work) through Apple Mail. I have tried deleting the keychain data and all manner of different ports/authentication combinations - the incoming server is fine, but the SMTP servers never connect. They always time out.
Is there a fix?

Hi Axiomatic48
I am in the UK and eventually found the problem was due to my BT Home Hub Router. Not sure where you live, but of you are in the UK, this might work for you.
I found this fix below on https://discussions.apple.com/thread/4604180?start=15&tstart=0
It worked for me. If you can't link to the URL, here is the body of the text
There's an issue related to the BT homehub that is providing a hostname that is "syntactically incorrect" for several smtp server.
Here's how you can fix it.
Using your internet browser, go to the address "192.168.1.254
- Follow instructions to reset your password if asked.
- Then go to "Settings", then "Advanced Settings" and "home network"
You will see there all the devices that are connected or that has been connected before. It's gonna be easyer if yout computer is the only one connected.
Your computer should have a name like "unknown-xx:xx:xx:xx:xx ...
Click on this name, chose another name without any special characters, like "macbook" for exemple.
And then click on "apply"
- restart your computer.
That should fix the issue.
Credit goes to vincentfromcork for providing me with the solution.
If this works for you, spread the word :-)

Still cannot send Mail (SMTP connection failed) post update.

PLEASE HELP!.......Post Maverick (and 10.9.1) I cannot send mail from my macbook pro. The message is "The SMTP connection to server "smtp.o2.co.uk" failed" I have trawled the many discussions about mail issues but most address mail inbox functionality and not sending. I have tried the OS X troubleshooting guide, rebuilt my mailboxes and created new accounts, all without success. All four of my o2 mail accounts are affected. Has anyone managed to resolve this issue? Would appreciate any suggestions

Ongoing issue for many people ... still not resolved until Apple fixes the SSL authentication in Mavericks:

Cannot send mail smtp failed

I am being connected to my Personal Hotspot.I want to reply to an email from the iphone but unable to. Here is the message:
The connection to the outgoing server "smtp.xxxxxxxx.com" failed.
Please help.

My problem seems to have magically solved itself, possibly when I changed the incoming mail server. I'm still worried it'll come back though, so if anybody knows how tonprevent the problem, I'd still like to hear what you have to say.

Smtp offline cannot send mails can receive

Cannot send mails from mac mail continues to show smtp offline however i can only receive mails, at my wits end

Try the Mailbox menu and select Take all accounts offline, then select Take all accounts online.
If this does not work, you should call your email provider. They may have changed their settings for SMTP, or you may be on a different network that requires different settings.

"Cannot Send Mail" App has the smtp address wrong.

After upgrading my 3GS Iphone to OS 5.0.1, I have been an error msg when trying to send mail:

I have deleted the account and set it up again several times. No luck!
Does anyone else see this error?
Any help?

Go into Settings>Mail, Contacts, Calendars>your account>Outgoing mail Server SMTP>Primary Server then turn Server ON and fill in both User Name +Password under Outgoing Mail Server.

Just updated to os x 10.9.2 on 3/5/2014 and i cannot send mail does anyone know how to fix this

i just updated to osx 10.9.2 on 3/5/2014 and i cannot send mail
does anyone know how to fix this (the smpt shows as off line - the certificate shows as none)

i figured out a solution if anyone is having the same problem
go to preferences in mail
pick the mail account that is not sending
if your outgoing mail server states it offline as mine did
click the dropdown and than click edit smtp
a window will come up that says account information and advanced
click advanced
renter your password and ok
restart your computer - when it restarts it will send emails

Cannot send mail with mavericks

Hi I'm using an iMac 2011 27 in. Shawcable is my ISP. I can receive mail. I cannot send mail. I get the error "cannot connect to account myaccount, enter password for user myname" If I go into accounts in mail prefs all smtp accounts show as offline. I have been over all my settings with shaw they say problem is on my end. They say my computer isn't connecting. Anyone have any ideas?

Without in details on what you have tried, I'll throw out some things:
On the SMTP server settings, use a custom port number instead of using the default ports.
Make sure you don't have any firewall, net-nanny, or other such network blockers running.
In Mail, Open Connection Doctor from the Window menu.
Click Show Detail, then Check Again.
Note any message noted in the stoplight section, and any related to the account in the details.
You may want to sanitize any of the messages from the Details so that it doesn't give away an email account or other identifying info.

TS3276 Cannot send mail from my iPad...."user name and or password is incorrect"......mail can be sent from my iPhone

Why do I get the message "Cannot send mail, the user name and or password for my email outgoing server is incorrect"? I use the same account, etc. on my iPhone and haven't any trouble sending mail.

If your email requires a password for the SMTP server you can set it up in the settings in the General mail setup. Some i.e Gmail require a password for SMTP.
Otherwise you will probably get better answers in the iPad forum.

Cannot Send Mail from my iPhone 4s

I am no longer able to send out replies or new emails from my phone, this is very recent and I have tried everything I know of.. But I am not THAT tech-savvy.
So, anyways, when I go to send an email or reply to one, I get a pop-up box that says "Cannot Send Mail - The username or password for "said"-hotmail account is incorrect." So then I go to the settings enter my correct password for my hotmail account, it accepts it, and try again. Same pop-box appears, even though my password and username are both correct. I know that they are correct because I am able to receive email with no problems at all.
Is this a fixable problem or should I call Apple or take my phone in directly to them and have one of the techs look at it ?
Thanks;
Odyssy

Problems with sending mail is rooted in the settings for the SMTP server. There are places in this that say the username and password are optional, but normally are required by many email providers. Go back into the SMTP server settings and check all of the areas. I also agree with Doctor9fan to check your SSL settings. If you cannot get it to work like this, then remove the account from the device and add it back. As you complete the creation, make sure the account verifies. You can also check the Microsoft site to make sure settings are correct for Hotmail.

Cannot send email SMTP to yahoo business email

i have yahoo business email, with 3 email accounts. iphone 3g will happily read the emails of the one account i want it to, but i cannot successfully reply or create new emails, send fails.
i tried to create a gmail account and use its smtp server. this worked for the gmail account, but still cannot send mail to the yahoo account.
tried to delete the outbound email server, but seems to be a bug in the interface - no matter what changes are made in the smtp detail, (even 'delete server') the smtp server for yahoo wil not delete. accordiing to some posts i read, supposedly if main smtp server is deleted, others in chain will pick up. this is not happening, when outbound function fails, it does not try with other smtp servers. yet send does work from gmail account!
what is the correct setting for yahoo? why cant i disable yahoo's standard smtp server as preprogrammed into iphone?

I have the very same issue. Can't delete or modify the "primary" account. All attempts to send result in the same, "Cannot Send Mail" message. As yet, I have heard nothing and the latest update ... 2.0.1 ... had no affects. Let me know if you find the solution.

Cannot Send Mail using AIM account.

I can receive mail fine but when I try to send mail I get the following message:
Cannot send mail using the server smtp.aim.com:EmilyLozano.
Use the pop-up menu below to try a different outgoing mail server. All messages will use this server until you quit Mail or change your network settings.
Message from: Emily Lozano <[email protected]>
I left for a trip a few days ago, came back and now for no apparent reason cannot send mail as I always have. I have reconfigured the port to 587 and that did not help. Any suggestions? (I can send and receive fine via the web, but I really hate it.)

I'm glad you got it figured out. So many times people on this forum sit around waiting for help when they could have retraced their steps, like you did, to figure out the source of the problem.

Cannot send mail from iPhone using Godaddy account/email

Was working perfectly until recently. Incoming mail still ok.
Now get error message when sending mail "Cannot Send Mail - The connection to the outgoing server "smtpout.secureserver.net" failed.
Have tried various fixes including using cwmx.com server, other ports and SSL on and off but no luck.
Have spoken to Godaddy support but they can't help as say must be local issue with iPhone.
Is GoDaddyGuy out there?

SizzyB and Joe,
I've read over your posts and see that you've both tried a few different troubleshooting steps with our support. The next step would be removing the whole email address from your iPhone and setting it back up. When you set up the email address, you should use the step by step walk through instructions available at http://help.godaddy.com/article/3423.
SizzyB, please note that cwmx.com is an AT&T specific server. Your UK provider might list a comparable SMTP server as a default or you might need to contact them to get their settings.
Joe, I would also like to note that you would specifically need to have our Unlimited email plan to utilize the IMAP service feature.
If either of you have further issues, please post the full details (including any errors messages you receive) and we'll continue to work on a solution.

Cannot send mail after upgrading to Lion

Can anyone help.
I upgraded to OS X Lion, and since then I cannot send mail from any of my accounts.
Nothing wrong with them. I can access, receive and send with othe Mail programs, as well as from my iPhone and iPad.
I have deleted, and reconfigured my accounts, and no luck.

I am having the exact same problem as Steve Kennedy a few posts back.
"When I press send I watch the fan for a couple of minutes before seeing the error message that invites me to select another server or try later. The outgoing mail server that shows up as being unusable is MobileMe (MobileMe). When I select smtp.me.com, I can send. Sometimes I can even send a couple of messages before the problem returns.
I'm using Lion and Mail 5.0 (1244.2/1244.3) on my iMac (mid-2010) and Verizon FIOS. Never had this problem with Snow Leopard or earlier. Don't have it with my MacPro running Snow Leopard on the home wireless network. Don't have it when using MobileMe mail on the Web, but that's a slow alternative."
I am getting REAL tired of the Lion quirks. <y desktop rearranges itself when it feels like it. Nothing consistent or repeatable. The folders just all appear on the right side and disregard how I have them organized on the desktop. I have set all of the recommended settings to no avail. A mind of it's own.
Help us Apple. Mail is almost unusable.

I keep getting a message "cannot send mail" a copy has been placed in your outbox. The recipient was rejected by the server because it does not allow relaying

I keep getting a message "cannot send mail" a copy has been placed in your outbox. The recipient was rejected by the server because it does not allow relaying. How can I fix this error so I can send emails.

The issue definitely sounds like your Outgoing/SMTP settings need to be changed. Simply set them to the proper settings for your provider as was suggested above.
I found this link for Knology: http://support.knology.net/content/email.setup.cfm
The SMTP settings can be edited on the iPad/iPhone by going to Settings--> Mail, Contacts, Calendars, edit the account having trouble, click the Account, then at the bottom is the SMTP server info, click on it to edit it further.
It should allow you to edit the primary smtp server and let you enter all the good stuff as you see in the Knology link above.
Some providers require you to register your account on their service like AT&T.

Cannot send mail A copy has been placed in your outbox. The recipient was rejected by the server because it does not allow relaying.

"Cannot send mail
A copy has been placed in your outbox. The recipient was rejected by the server because it does not allow relaying."
How can I fix my email? Now when I try to send an email I get the above message. It was working for months now it just quit on my ipad2, (but it still works on my iPad1 not updated to 5.0 operating system)? Help!?
Thanks,

Try going into the account's outgoing SMTP server settings, and if they are not already filled in add your account id and password to the outgoing settings : Settings > Mail, Contacts, Calendars and then select the account the account on the right-hand side and go onto into it's SMTP server settings
