virus 's that are 'sent' by the web user to another web user on the same Imail box.
ouch, I can't imagine how to attack that one.
> server. (perhaps Norton's will work???)
I get the impresssion they all grab the smtp port, scrub the mail, and forward it, so I doubt Norton NAVIEG will be able to insinuate itself between 2 Imail Web mail users.
We hope that the use of a dedicated relay will allow us to set up a wider
range of parameters to stop spam and to free up the neccassary resources for
heavy web usage.
This is the MailShield approach, and I'm leaning towards trying to build a mailshield type of box with OpenSource bits and pieces for well less than Mailshield's $5000, but I'm not enough of a *nix techie to make much progress very fast. There are lots of PERLy add-on bits for sendmail, qmail, postfix that could be assembled into a filtering/relaying ant-spam box, is the idea.
As I mentioned a little while back, Imail's filtering rules are pretty effective (while not quite being full RegEx level) and Imail has the relay/forward function, but unfortunately, Imail filters only for local domains, not for relayed remote domains. Too bad there isn't someway to filter for relayed domains. A plumbing issue. You'd still need another step, or box, for the virus scrubbing.
