autoresponder script?

[yoelu]

Hi!
I´m looking a script (full time server runned) that responds automaticly incomed and unreand gmail posts and turned it into readed for prevend to repear autorespod again next time that reload itself again (I suppouse that it might run in adition with a server´s time/schuddle aplication like cron).
It check in x minutes mail and respondes no read mails (think about time, it has to run independly the user´s petition when it has activated).
In adition, it could be interesting that the script sopportr filters (answer all except from X, or except subject X; or viceversa anseronly from X...)

I found and tried this scripts
phpclasses.org/browse/package/1997.html
and I think I changed all the necesary values, but it doesn´t run :S


Anyboody knows anithing about it?

Thanks
