Don't get me wrong....I love the fact that IMF is working (even though it took a little tweaking with the SCLs to get it optimal). However, I find it difficult to beleive that for an 80-user company we are getting that much junkmail. Much of the "sent to" addresses are either old accounts that were deleted some time ago, or accounts that we never had. Is there something that I am missing in the configuration? Could our server be replying to senders in some way propogating more UCE, or is it really normal to get this ammount?
Environment: Windows 2003 SP1 with Exchange 2003 SP2 over it, fully patched. No front end server configuration, single Exchange server.
In ESM: Message Delivery Options- Recipient Filtering is not selected; Sender ID Filtering Accept (default); Connection Filtering not configured (default) but some addresses have been allowed to global allowed list. Virtual SMTP server- Apply IMF, apply Sender Filter, apply Connection Filter.
Maybe I should just be happy that it's working, but I have to go through all the UCE every couple of days to make sure it's really junk.
