PHP mail() Yahoo! Problems

tried all tht ….. headres wer all fine, since it was landing correctly in gmail's INBOX ….. read much about the headers and stuff …. still dunno why … Yahoo was just refusing mails frm my server ….. so for now, i have used gmail's SMTP to send mails …. :p …. but still i want to use PHP mail() function … ne other suggestions ???

i had the same problem and mine just ended up being that it was sending to the same e-mail every time not to the senders e-mail.
