Mail Connections Lost After Sleep (Ports Fail)

mvtorres, Thanks for posting. To be dense-- I have 10.8.2. Is do I need to update further with a supplemental update? Thanks!

I had 10.8.2, but I didnt have Supplemental Update 2.0 so I had to install it.

I just tried to do it, but it says "this software is not supported on your system." I'm running a late 2011 iMac. I notice it says the update is for 2012 machines, so that must be why.

Same here, "this software is not supported on your system". I am running 10.8.2. I have a newer 27 iMac, bought it new in September. Same problem with mail---after sleep the mail connection to 1 of my mail accounts is lost. Manually I can revive it. I was hoping that this Supplemental update 2.0 would fix this, but my system won't let me install it. Any ideas why? Thanks.

Sorry, I spoke too soon, it was gone for about a day, but its back.

This is a very weird problem.

I have a rMBP 13" at 10.8.2 (mail 6.0) with the latest retina efi v1.1 update.

Gmail imap fetch fails after sleep or turning wifi off and then back on.

Note that my white macbook from 2010 (also at 10.8.2 and Mail 6.0) does not exhibit this symptom.

My router is a Time Capsule bridged to a Netcomm modem/router (NB304N); basically an access point.

I have experimented by unbridging the TC and running it instead as a DHCP/NAT router.

This has solved the mail issue with Mail 6.0

It just fixed it.

However, i am experience slower downloading speeds (potentially due to multiNAT) in the latter setup so i have reverted to a TC bridge.

Hopefully Apple can fix this bug in a future update as it is quite annoying; having to kill and relaunch mail everytime i wake my mac..

I had the same suspicion that it's got something to do with the Time Capsule. I have a Time Capsule bridged to modem/router, too (like mrbr1ghtside) and I think the problem only occurs when I am in this network. At the wifi-network of my parent or my friend, the problem disappears. Can anybody (everybody?) else confirm that? Do you all have a Time Capsule in your network setup?

By the way my computer is also a rMBP 13" at 10.8.2 (like mrbr1ghtside).

@ niqu

try unbridging your TC if possible.

issue appears to happen only with the rMPB and only when TC is used as access point.

hi, interesting clues have emerged. the power nap featrue works perfectly at my parents house. mac mail maintians it's connection when in sleep mode when i'm connected to their wireless network, however it continues to loose it's connection at my house. neither networks are using time machine.

to me this tends to point to a router or wireless network issue rather than a mac issue..

i have a verizon dsl router they have a cox broadband something...

bajawil, I have a verizon fios router, and I use a time capsule. For some reason this is only a problem on my 2011 Mountain Lion iMac, not any of the many macbooks we have in our household (about 5, from different eras, running every OS from Leopard to Mountain Lion).

I reported this issue during beta testing. Apple's engineers said they couldn't duplicate the problem and suggested it was related to Dropbox or some other third party app. I'm not convinced.

I, too, spent time talking with Apple tech support. They suggested it was a problem with dropbox or 1 password-- I don't see how that could be, either. Besides, I use those apps on my other computers with no problem. (Including my Air, which runs the identical OS.)

Well, I'll grant I do have both of those apps.

The issue for me is that even if that were the case, those apps are far more important to me than Mail's lost connectivity, so unless either Apple or the developers fix the incompatibility, the problem isn't going away any time soon. I'm certainly not going to ditch either of those apps to solve the problem.

I have tried ditching Mail a couple of times, but I don't much like the alternatives (Thunderbird is the best of a bad bunch, but it's just too darn ugly!).

softwater, my sentiments exactly. I need dropbox and 1P more than I need mail. I would switch to another mail ap or go to Google mail entirely, but I have over a decade of messages stored in Mail and I can't figure out how to transfer them in a way that I can access them when I need them.

I do not have any of these apps so I would be inclined to say that is not the problem.
