Comcast should have provided you with an SMTP mail server which they would lock down their relay-domains file to allow. You don't want to get into the reverse-lookup world, because many MTA's lookup against an RBL (Realtime Black List) specifically for dialup/broadband IP ranges. If your IP falls into that range, you're hosed. That's the way my mail is. The RBL I use is called Dialups.relays.OsiruSoft.com, among others.
look into an SMTP relay and point your Sendmail server to forward all mail through it (Webmin makes this easy, but there are a couple other ways) On Thu, 30 Jan 2003 12:46:17 -0500 (EST) Net Llama! <[EMAIL PROTECTED]> wrote: > Or even Netscape/Mozilla mail. > > On Thu, 30 Jan 2003, Aaron Grewell wrote: > > > This is a common anti-spammer tactic.
