I have Request Tracker 4.4 succesfully set up to use msmtp to send emails using account "support@domain.com" (used this manual: https://rt-wiki.bestpractical.com/wiki/Msmtp).
But, I need to send mail from "support-comment@domain.com", too. I'm thinking of enhcancing the msmtp_wrapper: catching sdtin to a variable, then parsing it to get "From:", then pipe it to msmtp, specifying "-a" (account).
Is there any sane workaround? Or is my solution the best possible?
