Can I safely remove this parameter from the master.cf file? (smtpd_recipient_restrictions); would that solve my problem and simplify my configuration? Or do I need this parameter in this location because of the way mail is passed through the domain keys? That depends on what restrictions you want/need to apply to port 587 vs. port 25. In All mail on this server must pass through domain keys which is through port 587. I've successfully run this server for this client for the last 3 years. We recently upgraded the OS and the client started sending a lot more mail (30,000 pieces at a time)- That's when we started to run into some problems. I might add that I'm not the only admin on site. http://www.postfix.org/master.5.html under the description of "-o" arguments, you'll find how to correctly specify complex parameter overrides in the master.cf file. -o name=value Override the named main.cf configuration parameter. The parameter value can refer to other parameters as $name etc., just like in main.cf. See postconf(5) for syntax. NOTE 1: do not specify whitespace around the "=". In parameter values, either avoid whitespace altogether, use commas instead of spaces, or consider overrides like "-o name=$override_parameter" with $over- ride_parameter set in main.cf. I did remove the whitespaces around the "=" and even simplified the smtpd_recipient_restrictions value in the master.cf but blacklisted mail still gets through. NOTE 2: Over-zealous use of parameter over- rides makes the Postfix configuration hard to understand and maintain. At a certain point, it might be easier to configure mul- tiple instances of Postfix, instead of con- figuring multiple personalities via mas- ter.cf. I will go over this document and see if configuring main.cf to handle smtpd_recipient_restrictions is appropriate. I'm reluctant to be this blunt, but you need to learn more about running a Postfix (or some other) MTA before you take on customer traffic. There are multiple serious issues with your MTA and you're in over your head. Thank you for your bluntness Viktor. You are right, I don't play around with the mail service once it's running but I will endeavor to "learn more about running a Postfix MTA" however, the situation is here and I need to address it. Personally I think it's the domain keys..I don't think they can keep up with the volume. I do thank you for your time and assistance though, you've been very generous and I do appreciate it. -- Viktor.
