Mailing list/mail server
 

I'm pretty much a linux newb. I have a server running mandrake 9.2, and i want to set up a mailing list to send out news to people once a month, i dont need to be able to recieve mail or anything, just send out an email to a list once a month. Can someone tell me exactly what programs I need and pointme to guides on how to use them. If possible i would really like a perl script or something, that will take email adresses via my form submit and either output them to a file i can copy to the mailing list adresses, or send it directly to the program. thx in advance
