I'm using the msmtp and msmtp-mta packages (Debian) to have a smtp relay for various services (forwarding to gmail).
This works well for various services, but with Authelia it fails with some errors (although the mail still comes through sometimes). I have found a relevant issue on the Authelia github that mentions the same SMTP RESET (RSET) command. According to the devs it is a problem with the mail agent, although it is part of the smtp specs.
At first glance, It seems to be exactly what I'm having: authelia/authelia#8457
