Where is the dcc timeout set? According to my "spamassassin --lint -D"
results it is timing out after 5 seconds, so I'm assuming that is the
dcc: check timed out after 5 seconds
I have 2 MailScanner servers with the same setup, and one is able to use
dcc and the other is timing out. I'm not sure why one would be timing
out and the other not? They are on the same network both using local
caching name server and both using the same DNS servers if it is not
cached. Is there a .conf I can check to find out what IP or dns name
dcc tries to connect to?
This message has been scanned for viruses and
dangerous content by MailScanner, and is
believed to be clean.
