I would have thought binding to specific ip/alias/interface in
case of multiple being present was already in msmtp.
Thanks for bringing up this feature.

Aren't there functions in the resolver libs for that? (Here I see one
for switching to TCP connections but so far not for setting src ip.
If not, this should be ticketed upstream as feature request in linux/bsd.)

You could also bind a named/unbound instance and point the
resolver there.
