You didn't want to publish an impressum on a website associated
with your mail server's domain then? ;)

(For those that don't know, it seems that T-Online.de block incoming
email from most IPs by default and anyone wanting to send them mail
has to explicitly contact them to ask permissions, and they make you
jump through hoops before they'll grant that - see recent posts on
the mailop list for more. It is quite astonishing.)
