I got the first relay spam via gmail STMP just 2 hours after I got
postfix + gmail working:)
The spam email claimed to be from xxx@example.com( which is the account
I registered to use with postfix),
and TO: not_exist@example.com How they can do that because accessing to
gmail's SMTP requires authenticantion
in which the password is in my server( /etc/postfix/sasl_passwd; chown
root:root; chmod 600; ).

IIRC, Usen blocks SMB and NMBD.

B Flets offer static IP hosting without port 25 filtering, but you have to 申請.
The performance will be better if you use WebCaster.
