By the way: We update the code on a regular basis, you don’t need to wait until we post these overviews. 🙂
 
 

Important changes for all moo cows

  • A mailcow fuzzy storage! Please contact me, if you want to share your spam with mailcow => info@servercow.de – fair-use, please.
  • Netfilter does now log the matched regex (finally).
  • Global sieve filters can be modified using the UI.
  • We score CSA crap relatively high now (X-CSA-* headers).
  • We do now use mariabackup for a fully-consistent backup of the SQL data directory. We will write the data to a tar archive in the future (see open issues).
  • Redis is now exposed to 127.0.0.1:7654 (FYI, has no further use in default setups).
  • We disabled TLS 1.0 and 1.1 for authenticated channels. We made a post about how to re-enable old protocols a few weeks ago.

 
 
A BIG THANK YOU to all supporters! Thank you so much for keeping mailcow alive. 🙂
Another BIG THANK YOU goes out to all contributors!
