HELP! No IMAP connection all of a sudden?!

[K9Marc]

Ok, I was a happy camper, everything was working great, then all of a sudden no one could log in??

Im using hMailserver on the same server as Round Cube with Apache 2.2
Here is the error from the logs:

 IMAP Error: Empty startup greeting (getallmail.com:143) in E:\www\vhosts\_dynamic\getallmail.com\www\program\include\rcube_imap.php on line 142 (POST /?_task=&_action=login)

What the heck?! I can log into the hMail Server from another Round Cube interface (different domain) I have running just fine.
But the main one just decided to not work.

Anyone please???
Thanks in advance!

Can you enable imap_debug and post the log here?

[K9Marc]

Yes sir I will, so the weird thing is it seems to be working again.

very strange..... I will enable and post.

Thank you.

It was most likely a temporary mail server problem then, try looking at hmailservers logs.
