Hi there, if you don't want to have your IP address blacklisted but still want to help the Tor network, then you could just run a bridge, so you still get to help the network and utilize otherwise unused resources, without having to expose your IP address, and without ending up on any blacklists/RBLs which could potentially affect email delivery. This may be of some use to you https://trac.torproject.org/projects/tor/wiki/doc/PluggableTransports/obfs4p... -alex On 22/11/18 9:08 PM, dlugasny@protonmail.com wrote:

Hi,

no its not possible. This is powerful VPS with single IP. I simply do not want to have blacklisted IP because tor relay is running on it.

In the past many times IP was blaclisted and afterwards I had several problems with email delivery.

I do not understand why rbls blocking tor non exit relay ip's... It stupid...

Is it possible to get a second IP address for that server from your ISP?

Hi,

I haven an e-mail server which has a lot of not consumed resources (CPU/Traffic etc.). Base on my practice I know that my E-mail server will loose reputation if Tor relay will run on the same IP.

Is there any other way to utilize resources of that machine without any reputation impact on the IP.

Thanks in advance for any feedback.

Cheers Dlugasny

Yes, very stupid I would say. I am not a fan of blacklists as a general concept, because of various reasons, they provide a false sense of security and the false positive rate can be gamed even by a child. I can't imagine what help it is for one to blacklist the IP of a middle relay. I can't imagine why would that blacklist have users that actually use it. This really has to stop, but unfortunately there is nothing we can do about it. Unfortunately for you, as long as the recipients where you are trying to send emails use such blacklist this can cause you problems with your outgoing messages and too little you can do at your side without stopping the Tor relay. You can for example run a VPN with a public dedicated / static IP address that you can use only for email traffic.
