Open GVogeler opened 5 years ago

Users report that the registration e-mail is put into spam or added a warning that it might be phishing and by this blocked.

Possible mitigation: check with https://www.mail-tester.com/ how to improve. Test result points to two blacklists for the server: BACKSCATTERER und SORBS (last 28 days) and suggest to check:

  1. [SPF] monasterium.net does not allow your server 217.72.192.75 to use root@monasterium.net
  2. Your message is not signed with DKIM

adjust SPF-Entries could be possible

I modified the postfix settings so the mail command uses the 1&1 server as relay server, so the spam-ratio should be better because the "official" server for the domain sends emails not the amazon server where mom-ca runs. I can't change the official server to be on the amazon server because the 1&1 email server hosts some mailboxes that are still in use. I hope this fixes some problems.
