Outgoing processing (filtering) is most powerful when you are scanning viruses. It helps to quell outbreaks for your customers and notify them immediately when they get "sick". We do this with Declude now and have save a few of our customers big dollars by reporting infected equipment quickly. (The equipment was infected by outside accounts such as hotmail etc...)

I am curious about this set up. I have, for | example, a FreeBSD box running qmail that functions as my | pre-processor now | (all incoming traffic for all the domains we host goes to it | first for virus | scanning and spam identification, then is routed to the appropriate | domain-level SMTP servers). | | I could have my Imail/Web server use it for SMTP delivery, too. The | FreeBSD/qmail box is fast and since this is all it does, it's never under | much stress. | | But how is that less resource intensive than having IMail deliver the SMTP | traffic directly? IMail would still have to use SMTP to send the traffic | over to the qmail box, right? It seems to me the same number of | SMTP dialogs | and transactions would occur... only just to my FreeBSD/qmail box | instead of | the ultimate destination servers. | | Am I missing something? I originally planned to use the FreeBSD | box for both | incoming and outgoing processing, but I thought it all through | and couldn't | see the advantage on the outgoing piece. (it is great for the incoming | pre-processing though). | | Mike | | | Please visit http://www.ipswitch.com/support/mailing-lists.html | to be removed from this list. | | An Archive of this list is available at: | http://www.mail-archive.com/imail_forum%40list.ipswitch.com/ | | Please visit http://www.ipswitch.com/support/mailing-lists.html to be removed from this list.
