mail() function problem

Dear All, I have a little problem with mail() function, PHP Code: -------------------------------------- mail($email, "Membership ok", $themsg, "From: webmaster@xyz.xom\r\n"); mail("grp-subbscribe@yahoogroups.com", "", "", "From: $email\r\n"); -------------------------------------- Why does the second mail() function did not ever send the email to yahoogroups? I wonder, can the mail() function be put in a loop structure (that traverse an array of emails) and send all emails successfully?
