Q: El Capitan Mail send error

Updated to El Capitan and Mail produces an error when sending e-mail:

 

Error Message:  "This message could not be sent because your account does not have a preferred outgoing mail server. Select an outgoing mail server from the list below." 

 

I re-entered the SMTP for outgoing and the error message has stopped but the outgoing mail fails and remains in the Outbox.  Receiving e-mail okay.

 

Does anyone have a solution?

MacBook Air, OS X El Capitan (10.11)

I've solved mine too! The server needs authentication, so you have to change the settings in the account, to password control and than fill in the username pass word for your own email account.

    I had this problem until this morning (mail wouldn't send since upgrading to El Capitain). I have fixed the problem in as much as I can now send emails through mail again, but had to log out my apple id on the computer to do it. The problem seemed to be that I was sending mail from an email address that was also my apple id. To clarify, prior to upgrading I had three email addresses enabled on mail, no problems with any. One of those (my main address) was also my apple id. After upgrading I could not send anything from that account (and I tried all the fixes suggested here). This morning I removed the account from mail and internet accounts, unchecking every box available, logged out my apple id on the computer (and logged in as my husband - we share devices), and then added the email account back to the mail. Now I can send mail again. I don't know why this is a problem with El Capitain, but if the email address you are having trouble with is also your apple id, this could be it...

    My apple ID is not the same as my local computer logon. And, all smtp but my oldest are still mostly "off line".

    After updating to El Capitan, Mail started prompting for a password when I send an email, and then said the password was wrong even though it wasn't, and it cannot send email.

     

    I was able to fix this problem as follows:

     

    In Mail, choose Preferences, Accounts icon, select problematic email account, in "Outgoing Mail Server (SMTP)" drop-down box, choose "Edit SMTP Server List...", and in that box, enter the correct outgoing mail server password and click OK.

    Congratulations.  Hopefully it will stay working, probably in part because Apple fixed the problem a bit in the two El Capitan updates.  Many of us did exactly what you did, and it either didn't work or worked temporarily, then suddenly started working again.  But I"m glad you solved your problem, and didn't undergo the two weeks of torture some of us did.

    Oh Gods, mine was fine until 10.11.2 and now screwed up. Originally suffered IMAP sync failure but I THINK that's sorted now (though since these problems seem to to come and go, not as confident as I'd like to be) - but SMTP seems to be frozen up. Connecting fine according to Connection Doctor and logs... just not actually sending anything. Toying with the idea of going back to a command line email client...
