Hmmmm...sounds like, as you said, you're doing all you can until the company changes its policy to be stricter on potential spamming customers.
Once they see fit to block port 25 for the wholesale dial-up users, and route all traffic through their own SMTP servers they should be able to identify spammers, and perhaps zombies, relatively easily and shut them down. Then the world would be a better place and we could all sit around the campfire singing Kumbaya...instead of staring bleary eyed at a screen in to the wee hours of the night...<grin> Darin. ----- Original Message ----- From: "Charles Frolick" <[EMAIL PROTECTED]> To: "Darin Cox" <[EMAIL PROTECTED]> Sent: Wednesday, December 08, 2004 3:39 PM Subject: Re[6]: [IMail Forum] Lycos goes limp Hello Darin, Wednesday, December 8, 2004, 11:29:57 AM, you wrote: DC> Hi Charles, DC> When your dial-up users do send through your SMTP server, do they have to DC> authenticate?

I do block port 25 on my dial users, but the ones dialing into the wholesale dial pools are *NOT* under my control. They are provided as a service from another company, and under their models it is not a good idea to block port 25 (They have multiple ISP's as subscribers). They do have to auth to use my server, since I treat them as foreign IP's (I have no idea what IP's they may come from). They do not, however, have to send through my mail server. -- Best regards, Charles mailto:[EMAIL PROTECTED] 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/ 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/
