yesterday I installed the upgrade from 5.04 to 5.05.
Everything works fine, no problems.
Today morning I have no new mails.
Also all my costomers which are configured for mail relaying havn´t got any mails.
After some tests from remote servers the mails will bounce wit simmilar messages like this:
194.xxx.xxx.xx_does_not_like_recipient./Remote_host_said:_550_This_mail_server_requires_authentication_(1)_when_attempting_to_send_via_this_SMTP_(submission)_port./Giving_up_on_194.xxx.xxx.xx./
At the SMTP Server Log there are Messages like this:

Only mails which should relay to remote servers was affected.
Now I downgraded to ME 5.04 and everything works with no problems.
So I believe this is a bug at the 5.05 release.
Can anyone confirm this bug?
