Dovecot - spam training through Outlook

[Claudius]

I have given up on using any spam training with Outlook because Outlook
seems rebuild the mails when you touch them.

What it broke here:

* Received Headers reshuffled and useless
* x-mailer set to outlook

There are multiple bug reports about this and MS seems to have fixed it
once in Outlook 2010 but broke it again sometime later.

I would be careful not to spam-report yourself with those mails since
they sometimes are rewritten to originate from your hosts by outlook.
Only the body seems to be preserved and even that might be re-encoded
with base64.

Regards,

Claudius
