 what MTA do you have installed?
 btw, sendmail *is* the standard for mail systems. :)

 if you mean that you don't have an MTA installed at all; look into  
 one of
 the send-only MTAs out there, like nullmailer(+debian patches), or  
 similar
 ones (can't think of the names right now; they all suck compared to
 nullmailer once the debian patches have been added to it). do a  
 freshmeat
 search, you'll find many.

 I use qmail on fedora.  I would like to be able to use a username/ 
 password
 to send mail and I cannot find where you would enter the password in
 backuppc, or if it is possible.  Any ideas?

I use qmail on CentOS and I have no problems using the default setup.  
Qmail has a sendmail interface, so it should just work.

Where do you enter the password for the email account in backuppc?

You don't. BackupPC just calls the sendmail binary directly. The  
default config.pl has:

$Conf{SendmailPath} = '/usr/sbin/sendmail';

You might have to alter this if your sendmail binary is in another  
location.

AFAICT, you're misunderstanding how mail works on Unix. 

Backuppc calls some executable program (the Mail Transport Agent, or MTA)
and hands it a big chunk of text (your message). No authentication is
necessary for this step, since it's on the local box.

The MTA then tries to deliver that message to the next machine in the SMTP
chain. This may be the destination machine (where the intended recipient's
mailbox is hosted). If that is the case, there's still no authentication
needed, since that's not part of communication between SMTP servers on the
Internet (this is why you can't easily stop spammers from bombarding you).

On the other hand, if all the machines on your network go through another
mail server (a 'smarthost'); that machine *may* have SMTP Auth turned on. In
that case, you'd need to configure your MTA (qmail in this case) to send the
username/password combination to authenticate to that server so it can send
mail.

Usually tho, the smarthost is just set up to accept mail from the client's
IP address (since it's not likely to change, and if the machine is
compromised then the username  password are available to the attacker
anyway so it really doesn't do any good). 

Does this make things a bit more clear?

Considering that qmail hasn't been updated since 1997 last I knew; it may
not be possible to set up SMTP Auth on it. (Unless someone wrote a patch).
SMTP Auth is really intended for roaming users who are trying to relay mail
through your mailserver remotely. Not for machines on your local network.

Without SMTP Auth; no password is needed to send mail. (Remember that this
was all designed back in the day when you could personally *know* all the
admins on the Internet; so they didn't think you needed authentication).

Carl - Thanks for the detailed explaination, so no SMTP Athentication -
okay  - I'll see what I can work out.
Cheers!
