SMTP session failed: 500 Syntax error, command "XXXXXXXX" unrecognized
Hi,
I was using mutt to send e-mail notifications via bash scripts for like two years now. Recently the emails stopped coming in. I did check the scripts on my server trying to debug them. Probably it's worth to mention that I didn't change the scripts for a long time now..
During the debugging I did find that mutt cannot send emails anymore and it's returning the following error message:
SMTP session failed: 500 Syntax error, command "XXXXXXXX" unrecognized Could not send the message.
I think it may be related to some recent upgrade of mutt itself.. I'm using: Mutt 1.13.2 (2019-12-18) on Kali Linux.
Can I ask if this is some known issue? Any help would be greatly appreciated.
