I have extensive mail filtering rules in place to move incoming mail into fifty or so folders depending on the incoming mail address, subject, and the message content.

In the last couple of weeks I've been plagued by spam trying to interest me in property investment.
Not a major problem, the spam filter drops in into the spam folder - but it's been annoying to go through and delete that junk.

I want to set a filter that looks for a common thead and just deletes the message silently. One difficulty is that the spam claims to come from multiple domains . But, the unsubscribe option has a recognisable pattern in it for all of them '/mw/index.php/campaigns'.
But, adding that as a filter does nothing.
Should the pattern be formatted differently?

Next problem, in messing around with that and setting up a POP rule set I seem to have lost all my filtering rules. Rules applied when folder is opened now shows no rules in the list and the navigation bar shows |||||||||||||| when that window is in focus.
I really don't want to have to set all that up again, and have a backup of the Pegasus directory taken yesterday.
Which file or files should I restore to get my filters back?

Thanks Malcolm
