Subject: Re: [BackupPC-users] Alert mails from BPC on CentOS 6 works, but not
from CentOS 5
It should hand things to sendmail for delivery. C5 should have a real
sendmail program configured to accept only from localhost by default.
Do you see anything in /var/log/maillog to indicate what happens to
them? If they go to another host, you may have to configure the
sending machine to use a domain name that can be found in DNS or it
may be rejected. C6 should have postfix by default, but that provides
a compatible-enough sendmail program.
========================
You were spot on Les. Thanks.
I looked at the /var/log/maillog and found a problem with the domain name, see
excerpt below. I'm not quite sure where it picked up localhost.localdomain from
and where to change it to the proper name. Does it look in /etc/hosts or
/etc/BackupPC/config.pl? And FWIW, I can't find an /etc/sendmail.cf for some
reason. Has this been removed and set somewhere else maybe?
Further, I discovered a problem with the installdir-variable on this particular
machine. It was set to /usr. Checking the working email BPC-server I discovered
that it should be /usr/share/BackupPC and changed it accordingly and then
restarted the BPC daemon. In fact, this errant variable might be why restores
have failed as it can't find the right scripts to run.

Anyway, as Google is my very good friend, I found this helpful little bit of
info; <<
http://www.adamsdesk.com/be/archives/2005/09/09/sendmail-dsn-service-unavailable/>>.
The specific info I used from this page was
1. Removed any reference to localhost.domain and/or localhost in my /etc/hosts
file.
2. Added "ALL: 127.0.0.1" in /etc/hosts.allow.
3. And for good measure (not necessarily required) added "sendmail: localhost"
in /etc/hosts.allow.
I then tested the mail function using the email from the BPC documentation;
# su -s /bin/bash - backuppc
# /usr/bin/BackupPC_sendEmail -u Sorin.srbu AT orgfarm.uu DOT se
And voilá, I got a mail from the BPC Genie in my mailbox. So, solved. 8-D
Thanks for the hint Les, it set me on right on track very fast. You and this
list rocks!
