The package description for msmtp-mta
documents that it is a wrapper which will pull in msmtp
as a dependency anyway.
This package provides the regular MTA program.
This is somewhat obscure, but apparently means sendmail
and newaliases
.
The package's file listing reveals exactly what it contains. As of right now (version 1.6.6-1) it contains the following files:
/usr/bin/newaliases
/usr/lib/sendmail
/usr/sbin/sendmail
/usr/share/doc/msmtp-mta/changelog.Debian.gz
/usr/share/doc/msmtp-mta/changelog.gz
/usr/share/doc/msmtp-mta/copyright
/usr/share/lintian/overrides/msmtp-mta
/usr/share/man/man1/newaliases.1.gz
/usr/share/man/man8/sendmail.8.gz
(In case you are unfamiliar with Debian packages, the stuff in /usr/share/doc/mssmtp-mta
is just standard metadata for the package, and the /usr/share/lintian/overrides
are specifics for the lintian
package integrity checker, probably to say that it's okay for it to ship the same binaries as some other packages which also implement the legacy Sendmail command-line API.)
So in other words, if you require sendmail
on your system, install the MTA package; otherwise the base package should suffice.
