Thanks Mike,
Good point! However, I've tried that this morning and replicated
~/.msmtprc to /home/backuppc/.msmtprc but unfortunately I'm getting the
same error message. Permissions are backuppc:msmtp and chmod 600. Not
sure what to try next, or instead but suggestions would be welcomed.

Hi George. I think you're missing a tiny important thing. You mention
when you send a test email as george that msmtp reads your local
~/.msmtprc. Wouldn't you need to also create one of those dot files
for the backuppc user that is calling the BackupPC_sendEmail routine?

*Subject:* [BackupPC-users] Test email errors
Hello,
I've recently rebuilt and reconfigured my instance of Backuppc
following a move to new hardware. All is well except I cannot get the
email to work, which is very frustrating as I did get it working
before, albeit 10 years ago...
I have Backuppc 4.4.0 running on Ubuntu 24.04.4 LTS. From previous
experience, I've installed msmtp as the MTA as I've found the
configuration easier than Sendmail. msmtp works fine when I'm sending
it from my normal account. It picks up details from the system config
file /etc/msmtprc and my user config file in ~/.msmtprc.
However, when I do
|su backuppc /usr/share/backuppc/bin/BackupPC_sendEmail -u
[email protected] <mailto:[email protected]>|
as per the documentation, and substituting my email address, I get the
error
Sending test email using /usr/sbin/sendmail -t -f backuppc
sendmail: account default not found: no configuration file available
And no email is sent or received. N.B. backuppc is set as ServerHost
and BackupPCUser in the BackupPC config. I suppose that is why it is
in line 1 of the error message, but I'm not sure why it's saying
"account default not found" because it does.
I have accounts in the /home/george/.msmtprc file for my Ubuntu user
account "george", "backuppc" and "default" to cover the bases but no
joy. They all have the same host, from and user details.
I think the permissions are correct:
root:msmtp for /etc/msmtprc
george:msmtp for /home/george/.msmtprc
and chmod 600 for both.
On BackupPC my SendmailPath is the default /usr/sbin/sendmail
and that is symlinked to /bin/msmtp so that's OK.
I don't think Apparmor is a problem: this file exists -
/etc/apparmor.d/local/usr.bin.msmtp and it's not listed in the status.
Is there anything I'm missing? Anything that BackupPC is looking for
in the msmtp or backuppc config files that I haven't already included?
Thanks for any help - I feel I'm missing something obvious...
George
