Q: Mail SMTP (outgoing) does not work after Yosemite upgrade

Hi there,

I had a similar issue as well, although with only one of my Mail accounts (Comcast); The SMTP was listed as (offline).

Try going to Mail -> Preferences -> Highlight the account with the issue and under the "Account Information" tab you should see "Outgoing mail server (STMP)" In that drop down there is an option to "edit STMP server list".

Once in the edit list, Copy down all the settings for the server the account should be using from both the "account information" and "advanced" tabs, then delete the listing using the "-" button and then using the "+" add the server again with all the information you copied down.

This worked for me without having to delete and re-setup the entire account, and I hope it helps.

google mail account refused to send mails in yosemite.

I've removed it and added it back. Now the mails are being sent successfully

There are several of us on Yosemite that are having trouble with IMAP mail.   Was working pre upgrade, now broken (constantly saying password is incorrect) after upgrade.

iPhone and iPad using the SAME settings still work so it's not the ISP or the settings (including username and password) but Yosemite.   Mail / Outlook and Thunderbird all have the same problem.

SMTP works its just IMAP thats screwy.

I have the same issue with my email out.   Email provider is AOL . They say  // nothing to do with them ///  contact Apple .

I receive emails without problems  but SMTP out server     does not seem to recognize the password .

For those of you having email password issues, I'd suggest:

1) Close your mail client (i.e. Apple Mail, Thunderbird, Outlook, etc).

2) Launch "Applications" > "Utilities" > "Keychain Access.app"

3) Select "login" from the sidebar top left area, then select "Passwords" in lower left area

4) Click into the Search box in the upper right and search for your ISPs server names.  For example, type "aol" or "google" or "comcast", etc.

5) Look through the search results for password entries related to your SMTP (outgoing) or IMAP/POP (incoming) mail servers.  Select them and delete them.

6) Open your email client and try to receive mail, and then to send mail.  You should be prompted to enter your mail username and/or password.

Hopefully this might fix issues for those of you using mail clients that use Keychain for credential storage.

Hey!   Thanks a million, that worked.   Hopefully that'll fix it for good!

Glad to hear that it was something simple.

WAIT A MO!

It worked, in that after I typed in the password it downloaded mail.   Life was good!

Then I closed Mail and opened.  Failed.   Hmm.

So deleted password again from keychain and entered it again in mail (as before).

But now it does't work.   Tried three times.   Still borked!

ARGH!   HELP PLEASE!

It is possible that KeyChain was corrupted during the upgrade.   There is a utility that can hep with that or at least verify that Keychain is not the issue.

In the  Utilities folder go to Keychain Access and launch it.  Under the KeyChain Access menu is a section called KeyChain First Aid.  Once you click that, d dialog box opens allowing you to verify the Keychain.

CAVEAT.  i haven't upgraded to Yosemite yet so this is how it works in Mavericks.

Ran verify - said all ok.   Problem persists.

Hi guys, im with the same problem... im waiting for the master with the solution.

Hi Guys, I have the same problem this morning,

Thanks Tim, I did step 1 thru 6  but with my SMTP outgoing mails I still get a problem, and have checked with our Server and no problem there.

@ Jay in Yosemite one still has First aid in the Menu section. Thank for that tip too !

I just upgraded to Yosemite and had the same SMTP connection problem.  I went into settings and found that my Mac Mail program was regarding my Lunarpages server as "not trusted".  I clicked on the box to "always trust" the server and that solved the problem.
