Mailscanner being bypassed?

[Brian Atkins]

Greetings. I'm relatively new to Mailscanner. I have a server running 
Sendmail 8.13.5, SpamAssassin 3.1.0, and Mailscanner (not sure which 
version). Today, I was working with the greet_pause setting in sendmail. 
I originally set it to default (700) and custom connection times for our 
internal clients (from our custom setting (5000)) to try and deal with 
local clients timing out when trying to establish a connection. It sped 
up the connection for the internal clients, but seems to have caused 
issues with Mailscanner.

At this time, I have moved the previous sendmail.[cf|mc] back in place 
and restarted both Mailscanner and sendmail separately seveal times, but 
it appears that I'm now getting a very heavy influx of spam messages. 
Also, the X headers (Mail Header = X-%org-name%-MailScanner:) seem to 
have disappeared.

I combed back through my sendmail config files and Mailscanner (also 
glossed over spamassassin), but cannot find any issues. I also dug into 
the documentation on the .info site and reviewed the list archives.

I would appreciate any input.
