Mail Monitor: help neede to filter subjects

Hi all.

I was wondering if there was a way to filter emails that have subjects like:

Code:

=?iso-8859-1?B?UGxlYXNlIGxvb2sgYXQgdGhpcw==?=

When trying to add the condition to the spam rule, Mail Monitor reads the subject as:
"Please look at this"

Maybe they are the same exact things, written in a different character set (or something), so in this case I could simply filter "Please look at this".
But I'd need to know for sure.

Mail Monitor decode all strings before filtering. This is "Latin-1" encoding. it must appear and text in Mail Monitor.

So the filtering condition based on the decoded text should work then, right?

Thanks for the reply, Yuri.
