" At the moment I'm just feeding lbdb manually from within Mutt (i.e. I'm manually picking messages to pass through to lbdb's in_mail module)."

Could say more about how you do that? Sounds interesting.

I'm also using offlineimap & mutt, with msmtp. I've just discovered lbdb, and currently I have implemented the compromise of running outgoing e-mails through lbdb-fetchaddr, by having "set sendmail" to a bash script that contains:


#!/bin/bash
tee >(lbdb-fetchaddr -a)|/usr/bin/msmtp -a default $@
