Soup....that'll kinda work. Problem is that I want to block everything with ISO in the subject line not just that particular one. Was thinking what I had would work....but.

If the subject always has =?ISO

Then the following should work. I copied your header and modified it in a few ways to double check. I'm just learning regex syntax in order to improve my sed and awk abilities so I made an example out of your header:

[code:1:747ce5a7a2]

workstation# more header

[/code:1:747ce5a7a2]

So
[code:1:747ce5a7a2]
^Subject: .*ISO[-,.{A-Za-z}{0-9}]+
[/code:1:747ce5a7a2]

looks like it should work for you. This won't match something like

Hey I mailed an ISO to you

or

ISO you requested

it will match anything before ISO and then most things but a space after ISO. If you wanted to grab spaces too that could be easily accomplished in a much simplier expression like so:

[code:1:747ce5a7a2]
^Subject: .*ISO.
[/code:1:747ce5a7a2]

Anyways, hope that helps. It was a fun exercise for me.

*EDIT*
That will match a line like

I mailed you an ISO.

but not I mailed you an ISO

I don;t know how a big a concern that is for you though.

I can use all the ones you wanna throw at me. Like I said I'm currently trying to get a solid handle on Regular Expressions, real life examples are what I'm looking for.

Ok...you asked for it.

How do I set Postfix so I can get a message telling me an email from you got rejected because of content?
