Well, I'll start with my standard response to this topic: SMTP != POP3 SMTP <> POP3 SMTP .ne. POP3
Now that that's out of the way, you don't let "inbound" POP access, you're allowing access to your mail server via POP3. Personally, I think that's not appropriate for most organizations, but for some it might be. It certainly isn't for ours, and I tend to disable POP3 on Exchange from the start. To address the attachments issue via POP, that's why my attachment filtering list is deployed both on our gateway mail servers, which manage both inbound and outbound mail as well as on the Exchange servers. With this scheme, all combinations of sender-recipient pairs are covered under the same attachment limitations. Roger -------------------------------------------------------------- Roger D.
