I stumbled across a mail script so long ago, I can't remember where. The person who wrote it included a bunch of headers, I might guess every type of header you can possibly use with PHP (but I don't know much about it).
I'd like to know what headers are necessary and which are recommended, whether or not they're they're in this script I have.
I'd also like to know if the ini_set line is necessary.
& if you have any other advice concerning PHP mail, kindly fill me in. Thanks.
