Hey folks,
Under Mac OS X 10.9.x using Apple Mail.app, we've noticed that Mail.app will frequently hold messages in the Outbox, and not actually send them for some minutes. (Maybe up to five?)
We've seen this when sending through different Kerio Connect SMTP servers.
Any thoughts?
Thanks!

Have you reviewed the mail log? Have you tried enabling SMTP Client in debug log to troubleshoot? Which version of Kerio Connect are you using? How are the account configured? Integration? IMAP/SMTP? Exchange?

We had this issue as well, tracked it down to using SHA passwords and having the MD5 Auth methods enabled, we disabled these and forced encrypted connections (all our users use SSL so no issue) - fixed all the delays we were seeing.

Thanks for the replies. I've checked into these issues, and here's what I found:
SHA passwords are not in use. MD5 auth is enabled, and I'm asking one user to switch to Password auth instead to test.
I enabled SMTP client and server debugging in Kerio Connect (v8.3.0). The next time the problem was reported, I reviewed the logs. In two separate instances, the logs show that a message was successfully sent TWICE from the Mail.app client (and then successfully forwarded by Kerio Connect to its destination). However, in the minute or two between when these two copies of each message were sent, the message sat in the user's Mail.app Outbox.
We will be updating Kerio Connect to the latest version.
Any other suggestions? This does seem like a Mail.app bug as far as I can tell.
Thanks!
