Mail 6.0 cannot connect to IMAP server, need restart

Ever since I upgraded to Mountain Lion, I am having problems retrieving new mail when I change internet connection. I checked Connection Doctor and it seems that I could connect to SMTP servers, but not IMAP servers. When I restart Mail 6.0, I am able to connect to the IMAP servers.


I never had this problem on Lion.


Is there a way to fix this? Thanks in advance! 🙂

MacBook Pro (13-inch Early 2011), OS X Mountain Lion

Greetings all! Well, I must say that the mystery here is partly solved for me. With the in-house network, we just rebooted the modem-router (one unit). Then everything was fine. Very strange... VERY strange. No idea what caused it or why. Some computers worked, and others didn't. Some were IMAP, others were POP mail accounts. It's a small network consisting only of a few hubs or switches and the Modem-Router unit. It's also a wireless and uses an ADSL connection.


I hope this helps others! Oh, and I'm still on LION, 10.7.4.

Having the same problem!! I'm also on Mountain Lion.

Mail suddenly stopped sending and receiving mail from both my POP accounts which had been working fine, even on Mountain Lion, although calendars and other applications have always been unable to connect to them since Mountain Lion. I went to the supplier and they applied maintenance on my account. Didn't work. I deleted both my POP accounts to create them again. Now I can't get pass the verification process. Can't find any up to date tips. I'm really frustrated and wasted so much work time on this. Did you find a solution?

I have the same problem on my new macbook with OS 10.8.2.

There is no problem on the macbook with OS 10.6.8.


Sparrow Client hasn't this problem, but it has other stupid bugs.

Simply in Sparrow I can't reply to All because it hide all addresses excluding first one . And I can't switch off grouping threads 😕


Waiting for fixing bugs in Apple Mail.

I have been having problems with Mail, my iCloud account worked fine but I could not send on my SMTP servers. Checking connection doctor and it logged into the POP servers OK but not the SMTP servers.


On another computer running OSX Lion everything was OK, it seemed to be a Mountain Lion / Mail problem.


In the end I fixed it by telling Mail to only use port 25 to connect to the SMTP server, once I did that everything worked again.


Hope that helps anyone having SMTP problems.
