Re: [IMail Forum] Tightening security on mail relay

[## Dusty Carden]

I would suggest Relay for Addresses and let users implement SMTP Auth on their clients.  I know it is a pain to get users to use, however it is easier than choking CPU time for thousands of SPAM relayed off your server.   Dusty ----- Original Message ----- From: [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Monday, October 18, 1999 1:27 PM Subject: [IMail Forum] Tightening security on mail relay We recently found that one of our domains is listed in a database of domains that could POTENTIALLY be used for mail relay.  Some administrators subscribe to these database lists and refuse mail from these domains.  We need to fix this!!   We are running IMail 5.x and relay for local hosts only.  They got around the local host only issue by sending from spammer@our_domains_IP_address!  What can I do to stop relaying when they use our IP address??   Thanks, Don Winsauer
