[rt-users] msmtp setup woes (continued)

[Stephen J Alexander]

Actually now that I reread your email it's evident that you can specify the
root cert in the msmtp config file. Looks like your mail server's cert does
not have a chain back to the equifax certificate you're using. So, get the
right certificate then specify the filename in the msmtp config. You can
verify it with openssl just as you attempted to do above.
