Hi
I'm green to Postfix. I have 2 anti-spam servers that I upgraded
MailScanner to the latest version and a completely new install of
MailScanner and postfix etc. All three have the same problems . the
one thing that is common to all servers is the original configs. For
the google-ing and digging around I'm still non the wiser. I have
looked file permissions etc, reinstalled MailScanner etc .. I'm out of
ideas, If someone with more experience could please advise me.
These are the errors I'm getting on all 3 servers :

These configs are the same for all 3 servers so the issue must be in
one of these .. But where I don't know. where .. everything looks
correct to me.. ???
Thanks for your time.
