Outgoing mail server gone under El Capitan

Similar Problem here. Did the 'IT' thing - turned it off and on again (as suggested below). Mail quit unexpectedly!! When I reopened, everything was fine. So I would suggest:

- Going to System Preferences > iCloud > disable mail option, wait a second then re-enable it

- Then quit Mail, Shutdown computer, reboot, restart Mail.

Hope this works.

The problem was easily solved for me. Here is the iCloud server settings. Just create a new SMTP server as in the instructions.

"System Preferences > iCloud > disable mail option, wait a second then re-enable it."

This worked for me, too, even though nothing appeared to change - my outgoing mail server was already populated with the same info that was there before the Yosemite to El Capitan upgrade - not empty as some have experienced.

Thanks OR-CD!

By signing out of my iCloud account and deleting it, then setting it up again, solved the problem for me.

Problem: The outgoing email is not working and takes us to the outgoing setting screen

Solution: I have managed to work around with this problem as i updated to el capital yesterday and this is how it worked for me. thats all u have to do.

mine righted itself somehow. I have taken screenshots of all the settings as they do not correspond with those suggested by my mail provider at all, but hey as long as my mail is working...

If only my computer could read your message and believe the "that's all u have to do." In my case, sometimes it works fine after doing that, sometimes it works after I undo that, and actually no matter what I do, it will eventually decide that it's unhappy and stop working. At least that's how it's been going since I first installed El Capitan, on the day it was publicly released.

Thanks - this solved the problem!

Odd that this was / is a problem with iCloud / me.com emails ...

HELP!! This fix seems to only apply to iCloud email users, it does not apply to anyone who has email accounts that are not iCloud emails. I have the same problem and cannot add an SMTP server, even when I managed to get to the edit list (which is gone from preferences, but did pop up on a failed email send) as soon as I add it, it disappears immediately and is not on the list. Also if you change one accounts outgoing SMTP from the drop down it changes them ALL. This is a nightmare.

Same problem as above. I'm not using iCloud but another provider. Keep getting asked form y password, then it tell she either the user name or password ins incorrect. The out going mail host sys disabled. Tried all the fixes above an no luck. I have had El Capitan installed since day one with no problems Mail until this morning. Seems like something has become corrupted but what?

Solved to me also!
To have or not have Apple support!!!

Thank you all.

Worked for me too!!

Up to now the only issue I had with Mr Captain was not being able to send emails, and now is solved!

I just disabled once the mail as suggested, and then back at the mail I sent a test note. and bingo!

thanks a lot,

🙂

Worked for me! Thank you so much
