Mail filter check in mail doby

Hi al!!

Can you help me please? I am trying to create a mail filter rule to DISCARD all incoming emails contains a link :

'anything'ub.php'anything'

All the spam emails contains this:
<a style=3D" font-size:12px; background-color:#ffffff;" href=3D"http://=
xxfaw.com/ub.php?tzs=3Dc9q9f3893630152a8bz1n6b40mkygpzp19rrthi5">K=C3=A9rem=
t=C3=B6r=C3=B6lj=C3=A9k a c=C3=ADmem</a>

And I want to catch the ub.php part because all of them contains that.

What I have tried:
Mail Content Filter -> Body filter
ub\.php
discard

Can you approve the Regexp. Pattern?

Thanks all, have a nice day!

 

I have tested, the good regex pattern is: /ub\.php/
