It looks like you aren't fabricating the right invocation of a command
for msmtp.  Did you set $Conf{SendmailArgs}?  Being an old Sendmail
diehard I've never used msmtp, so I ask not because I know anything
about it, but because msmtp is given as an example in the docs. :)

http://.../BackupPC_Admin?action=view&type=docs#_conf_sendmailargs_

If you look at the very last sub in the BackupPC_sendEmail Perl script
you'll see that all it's doing is running a command which you can run
yourself at the terminal.  Something along the lines of

$ cat messagefile | sendmail -t user -f backuppc

should do the trick.  Bear in mind that environment variables might not
be the same for user you and user backuppc.  PATH for example might be
finding a different binary to run if you run a command when logged in
as you and exactly the same command when logged in as user backuppc.
