Mail filter RegEx help

[GreGorGy]

Regex isn't my strong point. My hostgator mail filter allows for regex blocking and of late I have gotten a few spams with the following in the body:

<img src="http://www.somerubbish.com/[email protected]">

I want a regex that will match the above where the only thing that changes is somerubbish.

 

[Mudbream]

This should do it.

<img src="http:\/\/www\..*?.com\/unsubscribe\.php\?email=my@dom\.com">

Thanks - at least now I know where I went wrong. Failed on \/ and had * not *?

I will try this fix.

Guys... come now...

First off:

Matches everything in the HTML tag (DENY ALL HTML TAGS)

<[^<]+?>

Matches everything in the HTML tag that explicitly uses "img src" (DENY ALL "img src" TAGS):

<(?i:img\ssrc)[^<]+?>

And what you asked for with added sexy:

<(?i:img\ssrc\W+)(?i:https?://)((?:[\w]+\.)+)([a-zA-Z]{2,4})/unsubscribe\.php\?email=([\w-\.]+)@((?:[\w]+\.)+)([a-zA-Z]{2,4})">

You can ask for the POSIX alternative if your filter cant do PCRE.

PS: Please for the love of whatever God you believe in... stop using "*"

I will read these again tomorrow and feedback but Mud's answer is working for the moment.

Greg, Mud's answer is correct. But from someone who has built and managed far too many mail systems... It is far to static.
