[AusNOG] Mail Filtering + ISPs

[Tom.Minchin at csiro.au]

With dictionary spamming so popular, I can't see why you'd want to offer
a wild card redirection service these days. Just allow your customers to
do specific redirects and then they'll avoid having 5000+ randomly
guessed spam emails in their inbox.

Tom

PS at -2 SBRS you're blocked from us too (because of what you are doing
with wild card redirects to iinet - Senderbase is global).

Evening all,

Want to put the following situation into the list for discussion as it
is a problem for us, and I imagine any other web host. 

We have several customers whereby we host their domain under a "Domain
Forwarding" package. Simply put, we redirect *@customersdomain.com to
their own personal mailbox, more often then not this mailbox is provided
by their ISP. Some time in the last week we have had one servers
blacklisted by iiNet as our email spam rating has dropped to -3.4
(Apparently). 

For iiNet to begin accepting our email again we need to have a score of
at least -2. For our score to be raised we effectively have to "behave",
not send spam into iiNet, etc.

Effectively we will never get our score back up to that level, as I can
see that the clients who are forwarding their mail have spam sitting in
the queue waiting for them. If we do get back to that level it will only
be a matter of minutes before we are blacklisted again, I have ~400
emails sitting in the queue for iiNet / Ozemail currently.

I see no solution to this at all. Further so, as I can get hold of no
one at iiNet other then Support CSR's who play messenger between Sys
Admins and myself, I have sent this to the list. Really, I'm a Sys Admin
trying to rectify an issue YOUR customers are experiencing, is it too
much to ask I can talk to someone who understands the concept of
blacklists?

Any thoughts / suggestions / possible solutions (From iiNet or other)
would be much appreciated right about now.

Cheers
Nick.
