I am using Exim4 (not sendmail) and I've gone through all of the man pages. I was hoping that it might be something where hobbit was the one passing/forcing the from address. The only discussion close to something like this was about setting /etc/email-addresses which I mentioned in my post and I have tried.

I just wanted to be sure that this was an Exim4 issue and not a hobbit configuration issue before I pushed it over completely into that arena.

You need to configure sendmail so that it will use an account that Exchange recognizes. See the sendmail man pages.

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?

I'm using AIX and the standard email included with it. I have never had an issue like this, and I didn't have to do any special configuration to email when I installed Hobbit.

I can't tell you how to fix it, but it is definitely up to exim4 and
not Hobbit/Xymon to control this. I'm using Postfix, which is
configured to pull addresses from a user's entry in LDAP and if that
address changes, the from address on our alerts changes.

Because it screws up the order in which people normally read text.

To unsubscribe from the hobbit list, send an e-mail to hobbit-unsubscribe at hswn.dk

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 :-)

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

Hostname command returns "hhcgvl-moni03" as I would expect.

I am running Debian 2.4.27 - this is a machine that started out from the hobbit virtual appliance that was widely available for download.

Ah. Then there's no telling what may be pre-customized from defaults. A default Exim install should be returning hobbit at hhcgvl-moni03, which might not be accepted by your Exchange server, either, but wouldn't be as mysterious. I'd guess that either primary_hostname is set to a null string ("") or there's a rewrite rule that doesn't know its domain. You're probably getting better help than that over on the Exim lists.

By default, user at hostname will be used by Exim. Is hostname set on the system? IE, does the hostname command return anything? Alternatively, I think you can set primary_hostname in /etc/mail/exim.conf. As another pointed out, if you tell us what OS we'll be better able to help.

The exim list introduced me to a "qualify_domain" setting and I was able to force it that way. Thanks so much for your help.

It's great that you finally got it working - but in retrospect, setting the from address is really the job of the mail application (MUA) which the MTA should simply pass along if it's sane.

For future reference, mailx and postfix work "out of the box" for this sort of thing - no special hacks, MTA tweaks or secret settings required.

It should be as simple as aptitude install postfix. That should even
remove exim for you. I'm not saying you should use one or the other,
but installation complications shouldn't be something you worry about.

Don't try to tell me a thing is important to you if the whole of your
"support" entails forcing other to spend time and money on it.
