I use Procmail, SpamAssassin and Anomy for sanitizing mail.
From time to time a mail gets corrupted when going through the mail system: the attachments of the mail do not remain attachments but get into the mail body (and show up base64-encoded in the mail clients).
The corrupted mails are always forwarded mails (i.e. someone attaches an other mail to his own, the first having also attachments.), and always are marked by Spam Assassin as spam.
Is it SpamAssassin or Anomy that corrupts these mails?
Did anyone find a similar problem?
