mu4e and Emacs for email, as well as GPG for credentials and
mu4e-send-delay for delayed sending.
Sometimes the GPG prompt for the encryption password is overwritten by another message in the mini-buffer, and GPG gets the wrong password. The mini-buffer shows
Blocking call to accept-process-output with quit inhibited! and a pop-up dialog says
Buffer *temp* modified, kill anyway?. A copy of the message is saved in the home directory with filepath
This pop-up appears as many times as the number of emails to send and comes again after the value of
mu4e-send-delay-timer (60 seconds in my case).
The only solution I found (from How to force Emacs or pinentry to forget wrong GPG password?) was to kill the GPG agent with
gpgconf --kill gpg-agent and restart Emacs. Either of them alone is not enough, I need to do both. Then I get prompted for a GPG password.
I am using
GNU Emacs 26.3,
gpg 2.2.17, and
macOS Mojave 10.14.6.
How can I set up Emacs, mu4e, and GPG to be more user-friendly, maybe with a pop-up to request the password, and setting GPG to forget wrong passwords?
