Is anyone else having connection problems with Mail 6.2? I'm running OSX 10.8.2 and Mail 6.2 (1499)?
When Mail starts all my mailboxes connect to their respective servers (GMail, iCloud and an ISP). IMAP and SMTP connections are all good and mails can be sent and received. But then............ after a while (I've not timed it so I don't know exactly but say 20 to 30 mins) the connections begin to drop. First the SMTP connections to the ISP go then the SMTP ones to GMail then iCloud, then the IMAP connections drop. All connection settings are correct (it was working remember) and using the same connection settings on my iPhone everythig works just fine, but the Connection Doctor (Or whatever it's called) tells me that the mail account can't connect to the network/IMAP/SMTP server and asks me to check my connection settings. The only way to get it to work is to close Mail and restart it, whereupon everything is hunky dory for the next 20 to 30 mins.
As it's happening to all my mail accounts including Apple's own iCloud server I don't think it's a mail server issue. As I have internet connectivity it's not a network connection issue in that sense. As it was connected but then drops the connection I'm assuming that Mail is sending something it shouldn't to the respective server when it tries to connect to send and receive mails.
Everything was just fine until about a week ago and I didn't do any s/ware upgrades.
Is anyone else experiencing similar issues or does anyone have any help they can offer to fix it? It's kinda tedious to keep closing and starting the Mail App.
