URGENT: .p0f_socket exists but is not a socket

[Alexander]

I upgraded to v2.07 pro an sending and receiving mails did not work anymore. I downgraded to v2.06 pro, but still not working. I get the following errors:

Please advise

I updated to v2.07 pro again and the error above is gone, but still no messages are received or sent. If I telnet to the mailserver port 25 i get: 554 Blacklisted; please try again later or contact administrator

But the server ip is NOT blacklisted if I do an external blacklist check - so it must be something "internal" ... please advise ...

Ok, I found the blacklist issue, will open a new thread
