Thanks Ged,
I haven't set $Conf{SendmailArgs} in config.pl. What would I set it
to? Apologies, this is getting quite specialised for me.
I'm wondering if your environment variable point might be the cause of
the issue. Running the msmtp version of your suggested sendmail command
under su backuppc
cat test.email | msmtp -a backuppc [email protected]
results in this error message
cat: test.email: Permission denied
msmtp: account backuppc not found: no configuration file available
So it's maybe some problem with the backuppc user's ability to access
the config files which are currently sitting in these places
/etc/msmtprc (system settings)
/home/george/.msmtprc (user settings - works)
/home/backuppc/.msmtprc (user settings - fails)
What would the PATH changes need to be to allow backuppc user to see the
config file?
regards
George

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. :)

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.
