Mail
Resending Unix Mbox Files
Unfortunately someone screwed up the installation of one of our servers so that mail to local addresses was being delivered into /var/spool/mail/ instead of being sent onwards to our SMTP server.
Getting the sendmail.mc correct was the easy bit, there is a simple “null client” sendmail.mc file I wrote years ago which does that nicely.
The hard bit was taking all the Unix mbox files in /var/spool/mail and /var/mail and re-delivering them all to their intended recipients. The bit most people get wrong is the separator between messages. The separator is not a line starting with “From “. The separator is a blank line followed by a line starting with “From “. So I wrote my own script to do it which you are very welcome to download and use.
