Matt: We do not block outgoing TCP port 25 here but do monitor traffic volumes.

Well, I have not received a single response saying "we allow outbound smtp." I appreciate the feedback from everyone. Personally I'll run the change by my manager as a cover my butt, but in seriousness it is always good to get opinions before making changes that could result in unhappy users. Honestly I don't worry about the blacklists because our mail servers are of course not coming out the same Internet IP that our other networks are. However, they are on the same subnet so we always worry about the entire subnet getting blocked, although I have found in the past year or so that subnets are typically not blocked anymore.

It was not meant to be sent to the group. But since it was, I thought I'd follow up with a few questions of my own. Matt...how easy is it for you to make changes such as this without seeking permission first. I envy you a bit. We struggle sometimes at making some of what appear to be even most obvious changes. Also for Matt...how many "exceptions" did you have to allow to pacify users. Lastly...for all...could you help me in describing some of the threats to our institution if we did NOT do this? Thanks in advance. Randall Kreider Elizabethtown College
