Thank you!
I've checked the php settings, thy were exactly the same, as on the working server.
The problem was with the time: on the mail server there was a big difference with the real time!
Thank you for your help!
Have you checked out the php settings on your server? Specifically, have you looked at whether or not sessions are enabled in the php.ini?
