A day or two ago, my Tor exit host, Psychz Networks, has sent me complaints about my IPs being used to send "spam" despite me having blocked Port 25 (and 465/587) in the exit policy.
Psychz threatened to block Port 25 even when my exit policy explicitly blocks 25/465/587.
Yes, unfortunately you get this SPAM abuse, although it is clear that the mail was submitted via a webmailer :-(
Sometimes I think "is my FreeBSD exploited and being used to send spam", but then I also see Linux relays on other ISPs also on the blocklists.
It's actually very unlikely that a longer running exit can send mails. ;-) I can't even send myself log mails from my exit IP's because all IP's are blacklisted. On abusix.com and similar.
Yes, I am aware Tor exit relays will land on blacklists. But getting complaints from spam is new, especially when my relays are blocking SMTP.
I am worried I would have to find a new host if they continue complaining. Darn, Psychz has been one of the more reliable exit hosts (on-and-off) for many years, although they are more vigilant on abuse than say BuyVM.
If possible, try to get an ARIN SWIP record: https://blog.torproject.org/tips-running-exit-node/ 5. Get ARIN registration
99% of the abuse is f*cking auto-generated stuff from tools like fail2ban. If you reply, you will not get an answer or 'message is undeliverable' back.
BuyVM is similarly priced (although my Psychz is an special offer) and solid but has too many exits. OVH and TerraHost only allow exits on much more expensive dedicated servers. Prgmr and HostMaze allow exits but has so-so peering.
https://rdp.sh/ is not overcrowded yet.
I just hope Psychz doesn't continue to complain.
We all hope with you. As I've mentioned here before, IPv6 only relays are important. An AS with IPv6/48 is affordable. Then it's much easier to set up your own bulletproof ISP.
