Now, to continue looking for somewhere near Melbourne that can let me try out a frickin’ Steelcase Leap chair.

Actually I needed a solution for this yet again soon after the initial posting. That server was only running the default Sendmail. From memory, I added the domains I wanted to trap to a sendmail config file, then played with the aliases so that it appended all that email to a specified file. It worked rather well in that I could just tail the file and watch the raw emails accumulate.

I’ll have to dig that solution out and post its details sometime sooner than later. Thanks again.

I wanted to send mail from a machine that would not be able to have any physical connection to the internet – transporting mail should be done via removable media. And I wanted to be able to check the mails when debugging the software that sent them.

I found some documentation for qmail that described how to put all outgoing mail into a local Maildir (somewhere in http://www.jochen-solbrig.de/freebsd/dialuplan/dialuplan.html, IIRC) and send mail from there.

After browsing the docs I found that could do the same with postfix by defining a transport in /etc/postfix/master.cf:

ppp unix – n n – – pipe flags= user=ppp argv=/usr/bin/procmail -d ppp

and make it the default in main.cf:

default_transport=ppp

Obviously, a user named “ppp” had to be added to make that work. Now all outgoing mail gets dropped into ppp’s Maildir.

This user account looks like a normal user account to the IMAP server installed on the machine and the mails can be accessed (and deleted) from any IMAP-capable mail client.
