I changed the shell in /etc/passwd, so not via the #!/bin/zsh or
whatever.

Yea. obviously, cause there is clearly a difference with mutt in this
respect.

Thanks, i will try that tonight when i am home, but i can guess the
result and i think the end-result is that i would want mutt to
behave the same as pine and elm in respect to being killed when the
parent process dies independent on ownership. It must be possible cause
elm and pine also can. Better kill it than having a wild crazy process
which u can only kill manually with 'kill'.
