A bit naughty this, I got message from Nick Bolton at Firetrust (makers of the excellent Mailwasher product) to upgrade to latest version 4.01 . However after downloading, Mailwasher only works once and heres the rub your old registration key doesnt work! you have to fire of an email and get a new key. Even though his email says "all your existing settings will be retained".

Oh well I guess if you work against spammers all the time you must acquire some of their habits or "It takes one to catch one"

Thurs 20 May Update

Hi, it's Nick Bolton from Firetrust.
