[hobbit] How do I change the "mail from" for email alerts?

[Harold J. Ballinger]

My mail command does not support the –r option. I cannot see a way to force the from address, so I guess it is running it as the hobbit user. I have configured the hobbit user in /etc/email-addresses as “hobbit: monitor at mydomain.com<mailto:monitor at mydomain.com>” but Exim4 doesn’t seem to be using this. It definitely looks like it is something I will have to take up with the Exim4 group since now I can see the command that hobbit is using and that it isn’t the one forcing “hobbit@” as the wrong address.

Results from “mail -r”:

hhcgvl-moni03:~# mail -r
mail: invalid option -- r
usage: mail [-eIinv] [-a header] [-b bcc-addr] [-c cc-addr] [-s subject]
            to-addr [...] [-- sendmail-options [...]]
       mail [-eIiNnv] -f [name]
       mail [-eIiNnv] [-u user]
hhcgvl-moni03:~#

Thanks for the help guys, I’ll take this over to the Exim4 mailing list now :-)

My /var/spool/exim4/msglog is filling up with messages similar to the following:

2009-06-04 12:26:17 Received from hobbit@ U=hobbit P=local S=929

Process failed (1) when writing error message to hobbit@ (frozen)

I have reconfigured Exim4 to allow remote mail, but I can’t find a way to make the email alerts from hobbit/xymon use a different “MAIL FROM” than “hobbit@”, which our Exchange server knows is not a valid address.

I have tried making sure that the hostname is defined in the bbserver config and that the domain is configured in resolv.conf. I also tried creating an entry for “hobbit: hobbit at mydomain.com<mailto:hobbit at mydomain.com>” in /etc/email-addresses

I’m not a *nix guru by any means, and I’m sure this is something simple that I’m missing?


Did you adjust the relevant section of ~/server/etc/hobbitserver.cfg to suit your needs?

# For the hobbitd_alert module
MAILC="mail -r xymon at mydomain.com<mailto:xymon at mydomain.com>"      # Command to send an e-mail with no subject
MAIL="$MAILC -r xymon at domain.com<mailto:xymon at domain.com> -s"    # Command to send an e-mail with a subject
