mailinator-like service for QA

We're testing email based registration validation on a project. We started by using mailinator but a few times this has failed apparently because screen-scraping an ever-evolving AJAX UI is not particularly stable.

I decided to hack something up using my trusty old linux toolset.

Make a user account, maildump.

Get sendmail running.

Turn on FEATURE(`virtusertable`) in sendmail.mc

Add @maildump.example.com maildump

Set up an apach2 virtual host to ~maildump/web/

.procmailrc:

:0
/home/maildump/process.sh

process.sh:

#!/bin/bash

FN=$(mktemp)

cat > $FN

TARGET=$(cat $FN | formail -z -x "To: " | sed 's/[^0-9a-zA-Z\@\.\-]/X/g' )

chmod a+r $FN

mv $FN /home/maildump/web/$TARGET.html
exit 0

Now I wonder what security holes this has.
