Summary0011153: firefly blocked by DAN TOR blacklist
Descriptionbecause of entry/guard or exit node running on firefly.

Please check if that's really necessary, as deliverability can be negatively impacted by this.
Additional InformationI know from own experience running Tor infra privately, that (at least web) services on post.ch or rtp.pt cannot be reached at all, if you are on the DAN TOR blocklist.
TagsNo tags attached.

The DAN TOR blocklist is updated every 24hrs, which is the time it takes maximally to get off this list (if the list also gets updated regularly on the receiving sties relying on this service).

Another idea: can we bind Tor to only ONE of our two IPv4 addresses, and tell Postfix to ONLY use the other one?

https://netidex.com/articles/assigning-user-account-ip-for-outgoing-mail-sending-in-postfix-cwp-centos-ubuntu suggests how to get postfix to use a certain IP for *outgoing* mail. I am configuring Tor to only use the 219 IP, so if you set Postfix to the 218 IP we should be fine, right?
