That's right. "Relay for Addresses" or "No Mail Relay" are the only two options that will prevent outside spammers from sending mail through your servers. > > The general consensus is, use "No Mail Relay" and require SMTP AUTH > > on our mail clients. Either that or "Relay for Addresses" is fine (the only difference is that Relay for Addresses lets you enter "safe" IP addresses that don't need to use SMTP AUTH). > > The problem is, we have a ColdFusion server that must send mail through > this > > server, and the CFMAIL tag does not have username/password attributes.

"Relay for Addresses" is 100% identical to your existing "No Mail Relay" -- except that people coming from the IP addresses you specify aren't going to be require to use SMTP AUTH. So your existing customers, no matter what IP they are on, can use SMTP AUTH. > > Other settings that you guys might comment upon while pondering this... > > > > checked -- refuse NULL <> Senders This you should change, so that you can receive bounce messages. Hopefully, Ipswitch will add a big warning saying "THIS WILL MAKE YOUR SERVER NON-RFC-COMPLIANT" to a future release. Note that with this box checked, you'll end up in http://www.rfc-ignorant.org , and a small amount of your outgoing mail may not be accepted at remote mail servers. -Scott --- Declude: Anti-virus, Anti-spam and Anti-hijacking solutions for IMail. http://www.declude.com --- [This E-mail was scanned for viruses by Declude Virus (http://www.declude.com)] Please visit http://www.ipswitch.com/support/mailing-lists.html to be removed from this list.
