[LCA2019 Chat] DKIM problems

[Russell Coker]

https://doc.coker.com.au/internet/dkim-and-mailing-lists/

This list is sending out messages with broken DKIM signatures.  Could the list 
admins please follow the instructions in the above page (set "from_is_list" in 
the per-list configuration, set "REMOVE_DKIM_HEADERS = Yes" in /etc/mailman/
mm_cfg.py, and restart mailman) so that mail can go through without getting 
rejected or being put into a spam filter?

Also do we have some sort of template used for configuration of servers for the 
conference?  If so could it be changed to support DKIM mail so we don't need 
to have this discussion every year?

Below are some of my log entries about list mail bouncing.
