I' ve perused and searched the forums, but can' t seem to get around this. We have an employee that no longer works here from late 2006 that still receives a fair amount of spam, and well frankly I' m tired of the NDR' s generated by it, so I' ve tried configuring the firewall (An FT-60, firmware 3.00-b0564 (MR5 Patch 1)) to just drop all incoming mail to that account.
This is what I' ve done so far, to no avail:
AntiSpam -> Black/White List -> E-mail Address -> defined-emailbwl (edit)
And added the following:
E-mail Address: /mowens@mai-hawaii\.com/i
Pattern Type: Regular Expression
Action: Mark as Spam
and hit " OK"
In the Firewall -> Protection Profile -> filter_wizard (edit) I have under Spam Filtering " SMTP" checked (everything under SMTP is checked save for URL check), and in the E-mail address BWL check I have " defined-emailbwl" , and Spam Action set to " Discard" .
Under Firewall -> Policy -> wan1->internal, I have a virtual IP forwarding all SMTP traffic to my e-mail server, and the protection profile is set to filter_wizard. I know it' s enabled and catching most of the spam, because I can see via my FortiAnalyzer all the spam that doesn' tget through to my personal account.
What is the correct format of the Regular Expression (or should it be Wildcard?) of a specific e-mail address I want the firewall to block?
I' ve tried email@example.com (Regular & Wildcard), /firstname.lastname@example.org/i (Regular) and the latest, /mowens@mai-hawaii\.com/i (Regular), was done via information I' ve taken from these forums.
And nothing has given any definitive results. Is there a CLI only setting for this now that perhaps I haven' t come across?
Mahalo for any and all help!

Isn' t the correct way to not create a ndr?
I mean in every " normal" server non existent users should be denied 5XX in the smtp dialog therefore never create a ndr. accepting emails and bounce it afterwards is a very bad behavior as it creates backscatter to probably innocent (cause faked) users..
why don' t You reject that email with Your internal mailserver?
If You have a Exchange 2003 You can enable it with some tricks.
