The correct configuration is "SMTP AUTH" where the user must send along his user name and password in order to access your server.
Relaying of any other kind is verboten, and will get your system blocked. ====================================== Stop spam on your domain, use our gateway!

This however is | completely unrealistic from how I understand relaying to work for clients... | | Let's say I've got a client in California, who has a return address of one | of my local accounts, but hey, they're not sending email from inside my | network, so I originally said only allow relaying for mail with local | domain names in the FROM field... | | With spammers spoofing good FROM fields these days, ORDB says - no go.... | so then I think my only choice is to allow specific IP's... but how am I | supposed to know what IP a client is using if they're on a dial up account, | say through AOL or PacBell, or some little host in Iowa that forces dynamic | changing IPs with each log-on? | | Their IP changes. Surely I can't let ALL AOL IPs through or ALL PacBell | IPs through... there's got to be spammers on one or both of those right? | | So how do I deal with this? What is the correct configuration? | | Just as a side note - last year, before I even understood about relaying at | ALL, I had allowed ALL mail through, and of course, my server flooded one | day to the point of shutdown because some spammer found my server as an | open invitation! SO I truly need and want to do what's right here... hey - | I already get over 500 spam emails a day filtering through my local | workstation ya know? | | Rafael | | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Archives: http://www.houseoffusion.com/cf_lists/index.cfm?forumid=4 Subscription: http://www.houseoffusion.com/cf_lists/index.cfm?method=subscribe&forumid=4 FAQ: http://www.thenetprofits.co.uk/coldfusion/faq This list and all House of Fusion resources hosted by CFHosting.com.
