Er...ah...nonsense! If they ban port 25 traffic, SMTP AUTH is banned as well. You seem unclear on the issue, and unclear on IMail's options, as "Allow relay from all addresses" is not an actual setting (unless you're talking about the horrific "Anyone can relay"). I can't follow your logic, frankly. > Then your MSN users can use your mail server as thier pop3 and smtp > server with no issues with MSN. Um, care to test this out with daemons listening only on TCP 25 and 110 and traffic blocked to TCP 25 and 110? > The danger with this is logon and passwords are passed with clear > text. This is not true. SMTP AUTH CRAM-MD5 and POP3 APOP do not send cleartext. SMTP AUTH LOGIN and PLAIN are lightly encoded and easily cracked once sniffed, but not technically in cleartext. Only standard POP3 is in cleartext. > Next you should have a SPAM Policy with users signing the document > stating no e-mails with more than 50 address on them. In IMail, you can restrict the number of RCPT TO: commands. This is built into the product. Though, again, you're barking up the wrong tree. > Mull it over and let me know what happens. I've mulled it over, and I've decided that you should read my earlier posts on this issue and search the archives as well. ;) Or maybe you need to restate your points. -Sandy To Unsubscribe: http://www.ipswitch.com/support/mailing-lists.html List Archive: http://www.mail-archive.com/imail_forum%40list.ipswitch.com/ Knowledge Base/FAQ: http://www.ipswitch.com/support/IMail/
