  Does this problem persist? I don't seem to have any problems connecting my Gmail accounts?

  Are you on a slow network?

  You can hardcode the settings to use port 993 since Gmail does not support port 143 (although that is the recommended IMAP port). That'll focus MailMate on retrying on port 993.

  yes, it happened again today a few times now. The internet connection that I have is rock solid. I'll try the hard coded port and see if that helps. Having the email go offline for a while and not show me the new stuff is pretty frustrating.

• 

  benny February 27th, 2014 @ 08:12 PM

  I fully understand the frustration. I'll do what I can to help.

  You wouldn't happen to be located in Dallas? I have another user who had a weird problem cause by a Verizon issue described here.

  I appreciate it Benny... I am actually in Southern California and not on Verizon.

  When this happens then what is the result of running the following in the Terminal:

  openssl s_client -crlf -connect imap.gmail.com:993
  

  Just to make sure that it's only MailMate which cannot connect.

  The result is that the command line invocation worked correctly. "Gimap ready for commands"

  The account is stuck in a failed state with the activity indicator just spinning.

  The rest of the activity monitor pretends that it's synchronizing but it doesn't actually do it for the inbox as I know that there are a few emails that are not showing up like they should(checked via iphone mail)

  So it happened again and the activity viewer was open during the wind up to it... a bunch of ssl handshake errors. I did the openssl command that you wanted and it seemed to work fine:

  Thanks for the openssl output. It's a tricky problem since I cannot reproduce it (I have a couple of Gmail accounts online).

  When this happens does it then always work when you restart MailMate?

  If you get another log in Activity Viewer leading up to this then you are very welcome to share it. I might spot something non-obvious (or get an idea of what I could add to find out more about the problem).

  Hold down ⌥ when clicking “Check Now” to fetch the latest test version. I've tried changing some things and adding a bit more debug output. As before, keep the Activity Viewer open and provide the final lines of the logs as you did before.

  Thanks in advance!

  benny March 11th, 2014 @ 09:19 AM

  @Patrick: Thanks, this output looks as expected. It doesn't explain why the SSL handshakes fail, but for now I'll assume this is a server issue and threat it as gracefully as possible. Note to myself: I really should add some time stamps to those logs :-)

  It will only get better if:
  1. I take the account offline and then online again, or
  2. I restart mailmate

  Sorry about the late reply. Once again, I suggest fetching the latest test version. I haven't really looked into this particular problem, but the SSL handshake might include a more verbose error message now. Also, I've done some work on IMAP timeout values although I doubt this has any effect on this issue.

  Thanks for the feedback!

  Yet another test version in a few minutes. I still have no idea what the problem is. I did fix a (presumably) unrelated problem.

  Enable some additional (chaotic) output like this:

  defaults write com.freron.MailMate MmDebugSSLHandshake -bool YES
  

  Maybe it'll provide the hint I need to make progress on this issue.

  benny March 19th, 2014 @ 12:40 PM

  Thanks to both of you. Based on the output, I think it's pretty clear that you are having the same issue. As far as I can see the output from Patrick shows that the connection succeeds when retried, but the first error is identical to the repeated error in the output from Stuart.

  I'm running out of ideas and it's hard to debug when I cannot reproduce the issue myself, but I appreciate your patience.

  One quick attempt is to ignore the error reported and keep retrying for 15 seconds. This is done with this test version when MmDebugSSLHandshake is enabled. I don't really think it'll work, but it's worth a shot.

• 

  benny March 19th, 2014 @ 01:31 PM

  Here is another test version to try, but I would still like to know if the previous one made any difference.

  For this one you should enable this debug variable:

  defaults write com.freron.MailMate MmSkipSSLHandshake -bool YES
  

  (It doesn't really mean that the handshake is skipped. It means that it is postponed until it is needed.)

  Thanks in advance.

  Fingers crossed but it has behaved itself all day today!

• 

  benny March 20th, 2014 @ 01:06 PM

  @Stuart: Is this with or without the MmSkipSSLHandshake?

  (Unfortunately, I don't really like the MmSkipSSLHandshake fix since it doesn't really tell me anything about what the problem is.)

• 

  benny March 21st, 2014 @ 10:00 AM

  Another test version is available. I would like you to try out these settings:

  defaults write com.freron.MailMate MmSkipSSLHandshake -bool NO
  defaults write com.freron.MailMate MmUseDirectSSLHandshake -bool YES
  

  As noted I don't like MmSkipSSLHandshake and I seem to have problems when waking my machine from sleep (I don't know for sure that this is a related issue). With MmUseDirectSSLHandshake I'm using a slightly different API to make the handshake.

  Sorry about all the test versions, but it's necessary as long as I cannot reproduce the issue myself.

  Now it works with the latest beta 1.7.2 (4199) after reboot.

  Benny,

  I hit this issue tonight on an Exchange server I support (I've MailMate configured to use IMAP and it has worked OK till now on my infrequent sends from this server). I was testing email for my client, who'd reported an issue with sending. I tried a test that wouldn’t go out. I was able to send OK from my iPhone (ActiveSync) and through Outlook Web Access. I searched for the error and found this thread.

  I ran the openssl command you'd suggested (see below). Rather than open a new thread, I decided to add to this one - I hope that's OK. I'm running Version 1.8 (5029) (64-bit).

  If there's anything further I can do that would help, please let me know.

  The log is from IMAP (port 993), but the reported problem is for SMTP on port 465. Port 465 is non-standard and not all servers behave the same on this port. MailMate currently has a problem with that, but you can force MailMate to work (I believe) by entering 465s instead of just 465 in the settings window.

  I have captured 465 and 587 (which gives a relay error instead of the one seen on 465/465s, although SSL is selected):

  Ok, 587 is much better. You should use that, but I don't know why the server is rejecting the email address. That seems to be a server issue and not a MailMate issue?

  Thanks, Benny. I checked the settings on the server and it's now working OK using 587.

  Is it possible to mask the domain name in this thread?

  @Des: I've updated your comments to exclude domains/addresses.
