From the authour's web-site:
Nullmailer is a mail transport agent designed to only relay all its
messages through a fixed set of "upstream" hosts. It is also designed
to be secure.
We use nullmailer on a number of servers, where minimalist functionality is all that is required. All mail (typically only cron-job outputs, like logwatch and tripwire are then sent to our research-admin mailing-list, on ponyexpress.iat.sfu.ca. From ponyexpress, the admin-list will fire off copies to all subscribed research-administrators.
Install Nullmailer
hostname ~ # emerge nullmailer -va
This may pull in sys-process/supervise-scripts (or, you can emerge it manually), which will then require:
hostname ~ # rc-update add svscan default hostname ~ # ln -fs /var/spool/nullmailer/service /service/nullmailer (note: older servers use the /var/nullmailer directory, rather than /var/spool/nullmailer...)
Note: you may have to create the /service directory first, by hand...
and
hostname ~ # /etc/init.d/svscan start
Configuration
Edit the following files to configure the machine to send mail to our mailing server (Bismarck).
/etc/nullmailer/adminaddr
admin@ponyexpress.iat.sfu.ca
/etc/nullmailer/defaultdomain
iat.sfu.ca
/etc/nullmailer/me
$hostname.iat.sfu.ca
/etc/nullmailer/remotes
ponyexpress.iat.sfu.ca smtp
/etc/mailname
$hostname.iat.sfu.ca
Status
hostname ~ # mailq
Testing
(note: you may have to emerge mailx to get the mail command)
Send a message to root, then wait a brief moment for it to be picked up and sent onwards.
hostname ~ # mail -s "this is a nullmailer test" root Type your message, complete it with a ctrl-D + Enter
If everything is going properly, the adminaddr should receive a shiny new message in a short period of time!
Clearing the Queue
hostname ~ # rm /var/spool/nullmailer/queue/*
