[tor-talk] [Need quick help] 30+ mbps node taken down by host

[Name Withheld]

Hello,

My VPS fast tor exit got taken down by the host today for sending spam 
emails. Apparently the upstream provider complained to them about it. I 
thought SMTP was supposed to be disabled by default in the tor config, 
but apparently my node was sending stuff through (even though I didn't 
do anything to change the default setting for that).

The host is going to give me a chance to see if I can block it, but if I 
can't get the spam to stop, they're going to make me kill the node. I 
prefer not to do this kind of thing, but since it's their house, it's 
their rules.

Can someone please tell me precisely (what file, what entry) how to 
configure:

1) Tor to block smtp

2) Local machine to block smtp egress

3) Any other possible way to detect/filter outgoing mail Thank you very 
much
