That's not what the fixup protocol does. It basically strips anything out but HELO, MAIL, RCPT, DATA, QUIT, RSET, and NOOP, and doesn't send them to your SMTP server. So MAIL TO: would go through, but AUTH LOGIN: would not. And you're requiring AUTH to allow your external clients to relay.
So make your management choose. Do they want to relay spam? Do they want to allow your users to use POP3 at home? I say again, mailguard isn't necessarily evil. It just really doesn't do anything to add any level of security. > -----Original Message----- > From: Tony Hlabse [mailto:[EMAIL PROTECTED]] > Posted At: Friday, February 22, 2002 01:25 PM > Posted To: MSExchange Mailing List > Conversation: PIX fixup and E2K > Subject: Re: PIX fixup and E2K > > > With the smtp fixup applied.
