MAIL SPOOFING;NOT MAN SPOOFING
Halo GuRus, Any best solution to stop the mail from spoofing? Recently i have received mails that always send to me with other sender name.This sender did not send the mails. The sender name is INTERNAL USER but the mail was coming from outside smtp address. We can't block the sender to send mail, we cant stop the spoofing,what can i do? This actual sender is from 240.039.039.2 FOR EXAMPLE ONLY. His address book have my internal user's email address. He take from it and put it in the FROM Column. and send to me. Anyone out therethanks a lot Poor Fioon _ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin:[EMAIL PROTECTED]

The only way I can think of is to disconnect your server from the Internet.

One could install an SMTP gateway application which refused inbound SMTP mail FROM your domain. -Original Message- From: Ed Crowley [mailto:[EMAIL PROTECTED]] Sent: Friday, July 12, 2002 10:03 AM To: Exchange Discussions Subject: RE: MAIL SPOOFING;NOT MAN SPOOFING The only way I can think of is to disconnect your server from the Internet.

RE: MAIL SPOOFING;NOT MAN SPOOFING
Just f@rting around, I tried using Trend's eManager and hit a gotcha because we host some listservs inside our firewall. Outside addressees: Listserver-Outbound IMS-Firewall- addressee outside addressees pass through the firewall and the message is delivered. Inside addressees: Listserver-Outbound IMS- Firewall-bounces back to eManager(poof) Inside addressees , the firewall bounces the message back to the Trend box where it's dropped :( If both IMS's were inbound/outbound, my guess is this would work, but I'm thinking there's a few more things to think about- like having to create a rule for each one of 60+ domains, and I haven't thought about it to know what else yet. Sure not gonna fool with it on a Friday afternoon, but later...
