Re: [Declude.JunkMail] question about filters

If I have a user that is on a Verizon DSL. They go to email me from their Outlook Express, and they login to my server to send mail. Doesn't their mail client send a HELO/EHLO to my server when they go to send? And wouldn't it be an IP address and/or a in-addr.arpa PTR when they connect? (My users do SMTP Auth so they can use the server from anywhere.) Since the mail is to me then it would be considerend inbound email? Thus the HELO and PTR type filters in this case would be against them no?   -Josh ----- Original Message ----- From: Karen D.
