For several months now, I haven't been able to receive mail with mutt. When regrettably, I go into X Windows (MATE), I use webmail and see that google has blocked an attempt to log in and proudly says that the user (me) had my password. I'm guessing since it always happens when I make little changes in .muttrc to see if I can get mail with mutt, that it's because of mutt.
There used to be sample files inside the tar.gz of mutt tha contained sample dot muttrc files, I don't see them anymore. It's not mutt's problem, it's mine somehow. Best holiday wishes to all of you, David Ring
