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:


User uploaded file


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'm having a similar issue under Mountain Lion with Mail stalling forever when the internet connection changes during sleep (e.g. from wi-fi to ethernet, or from a wi-fi to another one). Quitting Mail solves the problem randomly only. Yesterday the problem started with Mail, then it extended to Chrome and to the whole system. I need to restart my MacBook way too often because that issue tends to freeze everything at some point.

I'd appreciate to know how to investigate into this issue.

Change MTU Size to Prevent Dropped Connections

This is a bit geeky but bare with us: MTU stands for Maximum Transmission Unit and controls the largest packet size allowed for transmission over the network. If this setting is greater than network capacity, the computer will experience packet loss and dropped connections. The default setting of 1500 is somewhat aggressive and some networks reject packets of that size, but it turns out that 1453 is just small enough to maintain a consistent connection with most networks but just large enough to not cause any slowdowns, it’s the magic number and an old cisco networking secret.

  • Open System Preferences from the  Apple menu and select “Network”
  • Click the “Advanced” button in the lower corner, followed by the “Hardware” tab
  • Pull down the “Configure” menu and set to “Manually”
  • Change “MTU” to “Custom” and set the field to “1453″

What does appear to work with me (in ways I do not fully understand): I deleted the Google Drive application from my system and the problem seemed to have vanished. This was at home, but this morning at work it reappeared. So I also quit dropbox, and put my mac to sleep, and lo & behold: on wake-up from sleep the problem seemed to have gone (no exclamation marks next to my IMAP accounts). I started dropbox again, put mac to sleep, and theproblem reappeared again. I also have an Exchange account, which does not suffer from the problem either.

Hmm, even with dropbox and google drive turned off the problem reappeared when going from work to home again. This is the log from the connection doctor. The offending accounts (red dots) are imap.gmail.com and imap.hubrussel.be:
