The idea of initiating chargeback is great. I did this couple times 
when vendor was everything but honest. If that's what you're going to 
I'd definitely like to hear what was OVH excuse for not following their 
policy as they have to explain and prove to the bank why the charge is 
Hopefully you'll get your money back.

I haven't thought about it that way. I run mailserver myself and 
fighting with
spam is daunting task. To avoid situation of automagically reporting 
spamming IP
to SBLs providers I'd like to implement solution that'll do both 
reporting and
whitelisting (have neither). Is someone familiar or have already in 
(or need - I'll try to write one myself) a script/config module to 
or postfix milter that will do two following tasks. One would be 
periodical download of
a public list of tor exit relays. Second would involve "spammy email" 
If an email passes through all filters and is deemed spam/malware/ebola, 
it should
be dropped, yet if it is received from exit relay (ip on the list 
downloaded on step 1)
it wouldn't do anything in terms of reporting anywhere. Otherwise 
forward for spam

I'm also thinking about second possible solution, but I'm not sure if 
it's possible.
On the host that's an exit relay, one would also have installed some 
of postfix (or other MTA) and not encrypted tor exit traffic directed to 
port 25,587
reroute to localhost's MTA for virus/spam scanning and then either 
forwarding or
dropping. Rerouting is doable in moments using iptables. I'm not sure 
what effect
that would have on the tor network and security though.
