Not sure of the usage of wildcards.  I have a list of blacklisted domains that I want to add wildcards to.  For example, if I want to block all e-mails from acme.com including things like ns1.acme.com, which would I use this: *acme.com?  Or do I need the @ like *@*acme.com?

Thanks

Rauco,
 
OK ... you will hate me but I would actually use the following RegEx:
((?i).+?@(.+?\.){0,2}acme.com)
 
This means Don't test for case, then one or more chars, then 0 or more chars+dot 0-2 times and then acme.com ... OR
The following:
mailto:jack@acme.com" CLASS="ASPForums" TITLE="WARNING: URL created by poster. - jack@acme.com
mailto:Jack@ns1.avme.com" CLASS="ASPForums" TITLE="WARNING: URL created by poster. - Jack@ns1.avme.com
mailto:JACK@bounce.ns1.acme.com" CLASS="ASPForums" TITLE="WARNING: URL created by poster. - JACK@bounce.ns1.acme.com
 
Regards,

Nope.  I don't hate you at all - I just have to find a good reference for RegEx!  lol

Thanks.  I'll be tacking that on the front of all the blacklisted domains I have until I expand my RegEx knowledge.

Rauco,

Remember that that was not a "simple" entry but a Regular Expression and as such must hav the ( ) around the expression exactly as I show or it will break.

Dan -

With the little I know about RegEx it seemed that the ( ) were needed but thanks for the heads up.

It works great so far and I've installed Regex Coach to get me farther.  Thanks again!

Dan,
Do you put this in your keyword filter file, black list email address file, or black list domain file?

Thanks.

This would be the BlockedFrom email blacklist.

Wouldn't it also work in the blocked domains?

It will but only if (I believe) the actual IP resolves to those names.
