sending mail pron

Hi guys,

i tried to use mail function to send email back to my POP3 mailbox but i can't receive the email ... when i tried to send it to other email account from different server or yahoo mail it just works fine.. in other words, it works fine if i send to other email host server but not myself..

why is that so ??? is that mean we can not use mail function to send email back to the POP3 account from the same server ??? or did i miss something ???

assuming that my website is myweb.com, then my pop3 incoming and outgoing server is mail.myweb.com.. basically from the same server..

p.s: hope u guys get what i am trying to say,..

please advise.
