- Does your problem resemble any of those in the links Mark sent? I tried [https://community.mailcow.email/d/637-problems-with-emails-keep-getting-reje...] and added a forwarding host to the configuration. Emails from an anonymous list were delivered, but the DKIM signature with the list domain was missing.
I've since found the solution: In the rspamd (mailcow) configuration, I added the following to the multimap.conf file:
whitelist_sender_domain { type = "from"; map = "/etc/rspamd/local.d/whitelist_from.map"; action = "accept"; }
And the whitelist_from.map file now contains lists.domain2.online
This means that emails from an anonymous list are now also delivered and signed :-)
Thanks everyone for your help!
