ISPC3 Inbound Email Issue
I am receiving the following bounce message when someone tries to send email to my ISPC3 server (Ubuntu 8.10):
<firstname.lastname@example.org>: user unknown. Command output: ERR: authdaemon: s_connect() failed: Permission denied Invalid user specified.
The strange thing is that it did appear to be working yesterday during initial testing!
The user DOES exist (checked spelling, etc). Tried doing a Google search (as well as this forum) and can't seem to find anything relevant.
