587 is the submission port. A mail server should accept mail on port 587 ONLY from authenticated sources. There would be no point in blocking port 587 outbound. Port 25 is blocked because it can be used to send spam directly to other systems. 587 can't be (unless, of course, the receiving system is misconfigured.) ========================================================== Chris Candreva -- [EMAIL PROTECTED] -- (914) 967-7816 WestNet Internet Services of Westchester http://www.westnet.com/
