Email to SMS Conversion

There's a program on freshmeat called email2sms ( that runs emails through a series of filters until they're short enough to be sent to a cell phone as a SMS message -- which typically have a maximum length of 150 characters. The script is mostly just a wrapper around the nifty Lingua::EN::Squeeze Perl module.

Squeeze takes English text and shortens it aggressively using all manner of abbreviations. It leaves the text remarkably readable for being about half its original length.

I ran the email2sms script for just a few weeks before running into a problem where an address sent to me by a friend was mangled past the point of usefulness. I figured that the best fix for that problem was to enlist the sender to evaluate the suitability of the compressed text.

To achieve that I added a feature to email2sms wherein a copy of the compressed message is sent back to the original sender along with a request that if important details were lost from the message during the compression process that they shorten the message themself and re-send it or send it to an alternate email address I provide on which no compression is done. The reply system has worked out quite well, and in the three years I've had it in place there have been a few circumstances were a human initiated re-send has saved an otherwise mangled message.

Attached is my version of the email2sms script, the configuration files I use with it, and a procmail recipe to invoke it. For fun here's the text of this post compressed by Lingua::EN::Squeeze.
