No email clients or servers should be providing HELO/EHLO as the MSU mail server IPs though. I see quite a bit of spam landing in my MSU inbox matching this criteria. Ex: Received: from [222.93.135.6] (helo=35.9.75.114) by sys14.mail.msu.edu with smtp Filtering off of this is a pretty standard practice, and shouldn't cause any problems. Did you run into problems with these rules? -Russell m. kolb wrote: > The HELO/EHLO rules reached End Of Life yesterday, as we found > additional clients doing the wrong thing.
