Re: using spf to reduce sys admin messages

I turned off NDR's but what users are getting is still emails from System Administrator (see below)


Your message did not reach some or all of the intended recipients.

The e-mail system was unable to deliver the message, but did not report a specific reason. Check the address and try again. If it still fails, contact your system administrator.

Is this some other kind of problem?

Outlook Rules. You'd still receive the NDRs, but you could have them deleted before they hit the Inbox which is all the user is going to care about. Depending on how many users you have, this could be significant overhead to set up, but if it's just your CEO or something then doing it is not a big deal and you can eliminate most of this stuff.

The big downside of course is that you'll eliminate the legit NDRs as well as the SPAMMY ones. Lesser of two evils.

What we've found is that a different user seems to get hit every day, getting 300-500 of these things, usually overnight, and by the time you get an Outlook rule in place it's over.

I think we all need to simply agree to turn off NDRs and auto-replies altogether, and follow-up every email we send with a phone call to confirm receipt. ;)

Thanks for your responses. Is there some type of recommendation to limit or stop some users receiving many emails from username System Administrator which are coming from a variety of outside sources?

agreed...if everyone rejected messages based on spf records, it might help, but many companies choose not to do that for fear of not receiving important email...

It'sd as good a plan of action as any. The theory is that systems that pay attention to SPF records won't accept the spam pretending to be from you in the first place and therefore won't bounce it when it proves to be spam. Secondarily, it may be that spammers will be less inclined to use spoofed addresses that have associated SPF records because those are less likely to get through. I think it does help somewhat but don't look for dramatic improvements.

Some of my users are getting 50-100 system administrator messages which they had not part in. We use groupshield on our exchange 2003 server. They recommended the Sender Policy Framework (openspf.org) as a means of reducing the messages. Does anyone agree with that? Is that a good plan of action or are there any other recommendations?


Thanks
