These extra parameters to the TSendMail function are used by imap_mail().
To use this function you need to load the imap extension but you get a few
more options that are not available in the standard mail function. See
http://php.net/imap_mail for more information.

ok thanks. but still, how is it that

mail('example@php.com','subject','body',"From: me@example.com\r\n");

should produce an error message stating "custom "From:" header missing"?

and is there any reason the custom header can't be parsed, and if a
"From:" header is found, to use that instead of sendmail_from value?

thanks again.
