Q: Outgoing mail server gone under El Capitan

Thanks. It worked for me

Could someone please explain what was meant by:

"Went back to Mail.app, hit send on iCloud outgoing email, and the outgoing server list popped up."

What is an iCloud outgoing email?  iCloud is not on the outgoing server list and I don't understand what is meant by "iCloud outgoing email." 

THANKS!!

Amazing! thank you

Thanks.  But that led to a different problem.

I have about 6 different email accounts.  I had account by account fixed them all, so each had its own active smtp server showing.  After I did what you guys suggested re iCloud, when I opened my Mail app, it showed a list of email accounts, each with its own Outgoing Mail Server item.  I went to the one of those that showed my iCloud email account (the whole email address, not just iCloud) and changed the Outgoing Mail Server on the pull down menu to the one that showed my iCloud email name. So far, so good. But all my other email accounts now are back to showing for its Outgoing Mail Server name as (Offline).  That's what I'd fixed when each account source told me the correct port number to put in, earlier today. 

So I'm still stuck. I want each account to show that it came from that account. 

It worked for me too! MANY THANK YOUS OR_CD!!!!

Because of the problem I mentioned that occurred after I handled the iCloud issue,  I just went back in and unenabled the iCloud email in System Preferences, and reset the port numbers in the other accounts.  Suddenly, they are now showing the Outgoing Mail Server name without the "Offline" at the end, and they all are working fine.

So my guess is that an enabled iCloud mail in El Capitan causes any other mail accounts to take their SMTP servers offline, although I don't  understand why.  That certainly didn't happen prior to El Capitan.

I'll keep checking to see if anything changes.

And if any of you have any other explanation or think I should be doing something differently, please let me know!  Thanks again.

Thanks, to OR_CD for this simple solution. Much appreciated!

It worked for me also ! Thank you very much !

Shouldn't have to do this, I had no issues updating to Windows 10, my elderly father wouldn't have had a clue how to correct this issue.

Walenut - You are correct, but after many, many years of helping friends with every type of Windows system up through the last one (I haven't played with Windows 10 yet), I'd still always recommend a Mac over Windows to people who aren't technically sophisticated, which is what I assume you are saying about your elderly father.  But you are right, when something goes wrong on any computer, it can be beyond the ability of some elderly (not all) to deal with. That's why I'd suggest something portable like an iPad or a Mac laptop to someone elderly, since worst case, they can bring it into their local Apple store's Genius Bar to get fixed.  I'd also suggest to anyone like that to not update to a new operating system on the day it is released, since there are always issues that get uncovered within the first month of a totally new op system being released.  El Capitan was released 4 days ago, whereas Windows 10 was released 2 months ago.  I doubt that your elderly father would have even known about a new operating system being released that quickly.   

I also have the same problem with iCloud Mail in the Mail app. I'll try your suggestion, and ..... hope.

Larry I totally agree with you but email is the life line to some people and business need it to be right first time, not everyone has ready access to local Apple store's, some technical issues I can except but this should have been sorted I understand it was an issue in the Beta version?

Thanks Walenut.  Sure re not everyone having a local Apple Store, but if I understood your message being that your elderly father might have been better off with Windows, the huge numbers of Windows support staff at businesses throughout the country raises the other option, namely that not everyone has a Windows support staff available to them either.  And I absolutely agree with you that email is often the mission critical application we all need.  Then again, my friends with iPads, who recently upgraded their op systems to iOS9 have had no problems with email or with anything else, for that matter.  As for me, as painful as this upgrade's email issues were, I was always able to use email for my business needs from my iPhone until I figured out how to get it working better, though not yet perfectly, on my Mac. 

Bottom line, it sounds as if you are a knowledgeable Windows guy, and if so, sure have your Dad use a Windows system.  But I'd still argue that despite all these things we are pointing out re our El Capitan installations, you'll need significantly fewer tech support people around in the long run if you are using Macs than Windows for business purposes,  And if your Dad needs Mac support and doesn't live near an Apple Store, he can always call Apple Support at 1-800-275-2273.  Depending on the issue, they may want him to be a subscriber to Apple Care, but that costs peanuts relative to what a Windows support person would charge. OR if this is still too complex for him, have him go to a local Senior Center, many of which have computer knowledgeable people.
