Mail Connections Lost After Sleep (Ports Fail)

I am having the problem that others are having regarding Mail reconnecting after sleep. Typically, it fails to connect to my Company IMAP server, and the IMAP Gmail server (but connects to the Gmail SMTP server). It looks like this in Connection Doctor:

I have done the following already:

1. Deleted and reinstalled the accounts

2. Reinstalled Mountain Lion from network

3. Reset my SMC


I have searched for any firewall that would mess it up, but have come up with nothing. Here is the readout from Terminal:


ls: /Library/InputManagers: No such file or directory

ls: /Library/Mail/Bundles: No such file or directory

ls: /Users/KyleEssary/Library/Mail/Bundles: No such file or directory

/Library/LaunchAgents:

com.Cvnt.start.plist

com.amazon.sendtokindle.launcher.plist


/Library/LaunchDaemons:

com.Cvnt.daemon.plist

com.adobe.fpsaud.plist


/Library/StartupItems:


/Users/KyleEssary/Library/LaunchAgents:

com.apple.AddressBook.ScheduledSync.PHXCardDAVSource.DB72A0D3-A7F5-42AA-B8C0-B9F DD21F52AE.plist


The CVnt plist is from an app that I added long after I noticed this problem. The problem was the same before and after installing that app.


Whenever I run the Network Utility following a wake from sleep on typical ports, I get this:

Whatever the issue may be, it apparently starts on sleep because Power Nap has yet to work. I have had this issue since installing Mountain Lion and would appreciate any help.

I was having this problem for a few weeks, but I believe I finally fixed it! I am cautiously optimistic. I tried this and so far have been able to sleep and resume and imap accounts reconnect.....


1. Quit mail.app

2. Go to the folder ~/Library/Containers/com.apple.mail/Data/Library/Preferences

3. Move com.apple.mail.plist to the trash

4. Launch mail.app


I hope it works for you too!

Changed my DNS to 8.8.8.8 (suggested somewhere on this site) for some other reason (my router's and ISP's DNS services not being very good I think) and hey presto fixed this at the same time.


I had resisted doing this but it's not too hard if you are prepared to dive into Settings --> Network --> Wi-Fi (or maybe Ethernet if you have hard-wired connection) --> Advanced... button bottom right --> DNS --> Press the + underneath the "DNS servers" pane, bottom left, and type in 8.8.8.8 --> OK --> Apply


Mail (and internet browsing) now working much better for a couple of weeks now 🙂
