Exchange "Categorizer" ??? what is it ?? 1

[pctekk]

We were/are using GFI to filter email to 1 domain and send to our exchange server as a relay host, but having some issues. So we stopped the relay host
and now when i tried an email to the domain in question,
and checked it in the Message Tracking,

I see it go to the SMTP: Message Submitted to Categorizer

is the last entry, then we never get any response
and of course they dont recieve it.

What is this CAtegorizer and is there another way to TRBST
this issue ??

Checked DNS on our side, the related domain's side...thanks for any info.

The Categorizer is used for expanding groups that messages are destined for. It also checks for mailbox size limits and restrictions.

so if a messages i sent OUT and tracked it in exchange, lists the categorizer as the last point, is it just lost ??
or delayed ??
