   Every message that comes in via the IMC is checked against each one of
your 'blocked' addresses.  As you can see, the more 'blocks' that you have,
the more intensive the process is to filter e-mails.  Every e-mail is
checked against every 'block'...  I too used to use this feature in
Exchange, but have another program that I now use on a separate PC.  All
this server does is filter e-mail based on content and also does virus
checking, then sends the mail into the 'exchange infrastructure.'  This has
worked well for me as well as taking a load off of my local Bridgehead

   You may want to try removing some of your older 'blocks' and see if they
are even needed any more.  The fewer the filters, the less the backlog.

Subject: [exchangelist] Exchange 5.5 -- Specify by host

I have been using the Specify by host option of the Internet Mail Service to
block e-mail from specific mail servers. Lately, though, I have been
experiencing problems receiving e-mail through the IMC. When the problem
arises, I have to restart the Internet mail service. Sometimes, though, I
have to restart the IMC several times before e-mail begins to flow. Does
having too many entries in the Specify by host list slow down or stop the
operation of the IMC?
