In my experience, YahooGroups is a bad thing. I say this as there was some idiot that set up a couple of groups, then proceeded to subscribe hundreds of non-existent accounts at various domains I own that have never been used for email!

Then this person started sending out messages, in Spanish, with attachments. I contacted Yahoo (by email with copies of the logs and finally by phone) and they said they would look into it but would not take my word for it that this idiot was sending to non-existent accounts. They said it was up to them whether or not to remove these account names from the group lists!

So after going through that garbage with them, I blacklisted every Yahoo groups server I could find and on my main CGatePro server I also blacklist by name. (the yahoo groups servers are different from the normal Yahoo servers).

SPEWS (spews.relays.osirusoft.com) is included on our RBL server list.
About a week ago, SPEWS added several of the Yahoo mail servers to its list.
As a result, much (most?) of the mail sent by Yahoo!Groups is getting
blocked. Other Yahoo mail is being blocked as well.


We have also seen examples of blocked mail that is clearly spam,
judging from the same mail being sent to multiple addresses that
are known *not* to be subscribed to any groups.  The volume of
this spam is not large, though.  Given a choice between a little
spam and losing a lot of desirable mail, we'd like to white list
the Yahoo servers.

Although I'm interested in commentary about SPEWS decision to
list Yahoo (justifiable in that spam *is* originating there,
but questionable in terms of disservice to a very large user
community) ... my real question regards white lists and white listing.

I've set up a few router entries of the form
   <[EMAIL PROTECTED]> = [EMAIL PROTECTED]
to allow some incoming groups mail, but this method
is impractical on a large scale.

It looks as though the Yahoo mail server IP addresses *could*
be put on the "client hosts" list, which would white list them,
but this would also introduce an undesirable security hole.

Are there other options in SIMS to white list specific
servers or IP ranges?  Something I've missed in the documentation?

Thanks.
