Package: msmtp Version: 1.6.3-1 Severity: wishlist My company's mail server is normally accessed through a round-robin DNS alias; but, for gssapi (krb5) authentication to work, I had to put one of the actual hostnames in .msmtprc (and set dns_canonicalize_hostname to false in krb5.conf because reverse-DNS is broken).
The server greeting ("220" line) includes the canonical hostname:
220 HOSTNAME.example Microsoft ESMTP MAIL Service ready at Mon, 11 Jan 2016
11:21:25 -0500
Please consider using this value, instead of the configured hostname,
for gssapi authentication. I'd do this by default, with an option to
disable it. It should be safe--RFC 5321 states:
"all the greeting-type replies have the official name (the fully-
qualified primary domain name) of the server host as the first word
following the reply code."
(Passing that hostname to passwordeval somehow might be useful too.)
