Tor and Spam :(
 

Hello All.
I use Tor with thunderbird but all of my emails sent to Spam, How can I fix this problem?

That really depends on how or what the recipients MTA filters for. Due to abuse by some TOR service users a lot of services stopped accepting and started blocking TOR node IP addresses. If you have a Gmail account, or any IMAPS account you can configure TB+TOR to use, try that?

Try to use bridges instead relays.
These are to much hard to indentify as tor relays because they aren't announced and listed in the main Tor directory.

here's the guide: https://www.torproject.org/docs/bridges

Tell me if it works...

My ISP blocks a lot of tor relays and with bridges my problems are gone... This are too usefull when you are under these conditions, that is the case of countries like China, and North Korea.

have you looked at " FreeMail" ?
it is part of the freenet project

You might want to have a look at Tormail, which uses Tor/.onion domains to access the "hidden" servers which then also use Tor routing to communicate with the public front end servers, which are true mail servers.
