Re: using spf to reduce sys admin messages

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
