Mailwasher & base64 subject headers
Does anyone know how to filter out spam in Mailwasher with subjects that are enocoded in base64, i. e. those that start with =?ISO-8859-1. . . . . . etc? It's doing my head in. I've reckon I've got the hang of creating filters for it pretty well, but I'm stumped with these 1s.

I've reckon I've got the hang of creating filters for it pretty well, but I'm stumped with these 1s. I tried to create a filter that just looks for the 1st part of the header [the =?ISO-8859 bit], but it won't recognise it - if I try sending myself a test email with just that in the subject it recognises it, but if I send myself 1 with the whole of the subject pasted from the source of 1 of these emails it won't recognise it. Anyone know how to block all spam with a subject that's base64 encoded? I don't know of any legitimate sources of email that use it.
