new mail() function

I recently downloaded the ArGoSoft mail server that someone on this list once suggested when trying to use the mail command on a window's system running php. I have since installed it and it works fine, except for the fact that my isp blocks connections to port 25 that will relay email to other servers. Tech support says I can do it using any other port tho. Is there a way to re-write the mail() function to do this? Or does the port specs rest solely with the mail server (which cannot be configured on which port to send to)? Help appreciated, suggestions welcome, better server software links honored, and yes i did read the manual on mail(). thank you __________________________________________________ Get personalized email addresses from Yahoo!
