I didn't say it was great, but interesting.
Better than totally blocking anything@hotmail. (I know several people
doing this).
And who said hotmail users do have any rights? ;-)
This is the first time I saw this in our logs (server running for ~6
months).
You could also look into the Received-Headers, but that would mean to
accept the mail first. Hmm. And headers can be faked.
Apart from this, only mails that were relayed somehow (e.g. forwarding)
would be blocked. None of our customers is doing this at the moment.
Ciao, Chtephan!
