Yes, but I'm pretty sure that would break TLS since msmtp sees localhost as CN
in its config and the cert CN says realsmtp.net. socat might be able to do that
TLS settings, but then there is not msmtp <-> realsmtp end2end TLS, only
socat <-> realsmtp, and msmtp doesn't know its results. And it requires managing
a separate daemon for each account provider user wants to send mail to. And
SOCKS4/4A doesn't work with IPv6.

Seems like msmtp having its own internal transparent SOCKS5 capability
would solve those issues. Right?
