I've potentially made some progress. It seems that sendmail had never
been installed so that has been done now. It's running as a service
fine but reporting various errors about unqualified host names. I don't
suppose this is really surprising because I haven't configured sendmail.
Running the test message command under su backuppc now completes without
flagging any errors. Unfortunately, though, the email doesn't get sent
and the mail is returned reporting authentication failures. e.g.
----- The following addresses had permanent fatal errors -----
<|[email protected]|>
(reason: 550 Authentication is required for relay)
----- Transcript of session follows -----
... while talking to mail5.hostinguk.net.:
AUTH dialogue
<<< 535 Authentication failed
MAIL From:<|[email protected]|> SIZE=527
<<< 550 Authentication is required for relay
554 5.0.0 Service unavailable
Again, this may be because I haven't configured sendmail. But I have
configured msmtp and it works correctly from my normal user account.
Running an msmtp command under su backuppc results in the error
msmtp: account backuppc not found: no configuration file available
even though there is under /home/backuppc/ (as per Mike Hughes
suggestion a couple of days ago).
It seems as if the backuppc user is missing and/or not able to read the
config files, but I can't see how to fix.

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. :)
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.
