Thank you for your answer! But this does not answer my question: I
know that it is possible to manage multiple identities that way, and I
was trying to find something more flexible.
You could put the post-the-script stuff in the script output.
macro index A ':`shell-script-emitting-mutt-commands`<enter>'
Then your shell script can run your menu selection of identity (use
/dev/tty for the output here, since stdout will be going back to mutt)
and then have it write whatever you like to mutt, for example an
instruction to source an identity setup file.
Thank you very much for the pointer, I'll try to do that, and indeed I
think that doing something like the above will do the trick!
