RE: [IMail Forum] Our server is relaying for spammers and I don't know why! Any help greatly appreciated!

I've now removed all but a scant handful of IP's from our trusted list.  I had, I hate to admit, anyone whose connectivity was provided by us trusted thinking that they still had to have an address on the server.  Our instructions to our customers detail SMTP auth.  I'll have a few customers that are using fax machines and other devices to send some mail who will have issues but I'll deal with those individually.   Katie LaSalle-Lowery Centric Internet Services 1410 Reserve St. Missoula, MT 59801 Local Phone 549-3337 ext. 21 Toll Free (888)593-2776 ext. 21 Fax (406)721-3438     From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Darin Cox Sent: Thursday, December 09, 2004 2:40 PM To: [EMAIL PROTECTED] Subject: Re: [IMail Forum] Our server is relaying for spammers and I don't know why! Any help greatly appreciated! Trusted addresses do not have to authenticate.  That way if you have an SMTP gateway you can route traffic from it.

Any help greatly appreciated! I found the issue... The mail was originated on a trusted IP (one in the relay address list).  We have a customer with a trojan or something.  I've un-trusted that address.   However, I'm still confused.  I thougt a valid address was still required.   Katie LaSalle-Lowery Centric Internet Services 1410 Reserve St. Missoula, MT 59801 Local Phone 549-3337 ext. 21 Toll Free (888)593-2776 ext. 21 Fax (406)721-3438     From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Katie LaSalle-Lowery Sent: Thursday, December 09, 2004 2:05 PM To: [EMAIL PROTECTED] Subject: [IMail Forum] Our server is relaying for spammers and I don't know why! Any help greatly appreciated! Our Imail server is set to "relay for addresses."  I discovered today it is relaying.  Don't know how long that has been the case.  The messages are stacking up by the hundreds in the queue and I'm at a loss...   Any suggestions would be greatly appreciated!   Thanks!
