Re: Spam Question
Why not patch sendmail ? "Brien Mayer" <[EMAIL PROTECTED]> wrote in message news:277188@exchangelist... We are using sendmail as our front end server to an E2k server. It seems someone has found a hole in our sendmail server & are able to spam us. I received 4300 e-mails over the weekend. My question: Anyone using sendmail as their front end server & if so what spam software are you using. Is their any free downloads that work good.

RE: spam question
I agree. I spend 8 or more hours each week going though spam messages forwarded from users to pick out keywords to place in out spam list. I think the best way is to educate you users and create a basic filter list to maintain. There is always the issue of explicit material in email either outgoing or incoming.

RE: spam question
Title: RE: spam question I understand the issue, and yes relaying can be handled at the firewall. What I was questioning was the idea of filtering spam (or house, whatever) at the firewall.

RE: spam question
If you open up the Internet Mail Service connector, go to the Internet mail tab, and click on the advanced options button, there is a check box to disable Automatic Replies to the internet.

RE: spam question
On the spam thread -- If someone sends a message (right domain, wrong user - intentionally) would if not go right by the firewall and/or Exchange relay checking, and generate an NDR back to whoever is in the "MAIL FROM:" in the header? It's not a "relay" but it can have the same effect -- if the spammer put different victim's addresses in the "MAIL FROM:" in the header, an NDR would go to the intended victim(s) and not back to the spammer, would it not? I think this is what the MS white papers on securing the Exchange relay refer to as reverse UCE. Would a spammer even want to do this - does it actually happen or am I just off on another maniacally paranoid delusional adventure here? Is there a way to prevent this (the reverse UCE, that is...)? -Original Message- > From: Schwartz, Jim [SMTP:[EMAIL PROTECTED]] > Sent: Tuesday, February 26, 2002 1:36 PM > To: MS-Exchange Admin Issues > Subject: RE: spam question > > It's also a waste of resources as the mail still has to travel through the > firewall, into the IMC, get routed to dev null.

RE: spam question
It's also a waste of resources as the mail still has to travel through the firewall, into the IMC, get routed to dev null. Better to block them at the firewall (if possible) and return them a 5xx error. Dropping the request (as some do) returns a 4xx error so the mail will queue on their systems and retry. As too why they would have a read receipt is beyond me. Most spammer could give a damn if their mail gets there or not. They are charging by the piece sent, not delivered. Spam houses take the add, merge it with a database of names and open up the mail cannon. Relayers wouldn't want a receipt anyways. That would give me a way to go after them directly rather than try to get the open relay to shut his hole. > -Original Message- > From: Drewski [SMTP:[EMAIL PROTECTED]] > Sent: Tuesday, February 26, 2002 1:09 PM > To: MS-Exchange Admin Issues > Subject: RE: spam question > > Doesn't that violate RFCs? :P > > -- Drew > > Visit http://www.drewncapris.net!
