As you might suspect, one of the IT people at this company who has been there 20 years wrote the thing. I tried. That was my first suggestion. That would fix graylisting (which I don't do), fix SPF an SPF HELO, and SENDER ID, blacklisting, tarpitting, etc. MIGHT fix p0f, but don't know. I am going to write up a whitepaper on why NOT to put an anti-spam/MTA behind a proxy, cite all relevant, good suggestions and send it to them. _________________________________________________________________________ This email has been scanned and certified safe by SpammerTrap(tm).
