I wrote a simple PHP script using PHP's MimeDecode module. This script
takes receives a message on stdin (via Postfix 'pipe') with one or more
attachments, writes each attachment out to a temp file, then calls
Hylafax with the appropriate arguments and a list of the tempfiles - and
then deletes the temp files.
This functions - but it strikes me as inelegant. I'm also concerned
about possible breakage points, including:
1. One or more large attachments may result in significant resource
consumption. Being able to attach a 50-page manual and click "send" may
become an attractive option to some users.
2. If, for whatever reason, there's a break in processing in the
script, there would be a quantity of temp files that wouldn't be deleted.
I suppose if I was using a consistent naming scheme for the temp files,
or placed them in a subdirectory, I could use an hourly cron job to make
sure they were cleaned up. That approach has always bothered me - but I
don't know of a better one.
Anyone have any suggestions on alternate implementations I might pursue?
