Dear all,
I accidently posted this message to dovecot-news and want to apologize
for any trouble I may have caused. Here it is again to the correct
mailing list:
Recently I'm getting a ton of porn/viagra/diet/casino spam mails which I
tried to filter with sieve:
if header :contains "Subject" [ "[SPAM]",
"Bett",
"Schlafzimmer",
"Spielen",
"Luder",
"abhenmen",
"poppen",
"Casino",
"Bonus",
"abnehmen",
"Gewinn",
"Potenz" ] {
addflag "\\seen";
fileinto "Spam";
stop;
}
Sadly, this didn't work - taking a closer look upon one of the spam
mails, it seems the spamming rats have encoded the subject:
Subject: =?US-ASCII?B?RW5kbGljaCBtZWhyIGVuZ2FnZW1lbnQgaW0gQmV0dGNoZW4=?=
(reads: "Endlich mehr engagement im Bettchen")
I'm thinking about filtering all such encoded subjects (as there's no
reason to encode them US-ASCII), but suppose it were UTF-8 or something:
how can I filter on the actual content, not the encoded subject? Surely
someone has solved that problem already?
Kind regards,
Johannes
