RE: [PHP] Sendmail and php4

Have a look at the error - server_domain.comr does not resolve - that means that the mail server is set to refuse mail from senders with domain names that don't resolve to an ip address <nobody@server_domain.comr>... Sender domain must resolve This isn't a php problem, its your mail server configuration. Its set that way to stop invalid senders. Try sending with a correct return address. eg $email="nobody@yahoo.es"; mail ("any@any_domain.com", "A$sesion_id", "$mensaje", "From: $email\nReply-To: $email\nX-Mailer: PHP/" . phpversion()); Cheers, Lawrence. -----Original Message----- From: Maximiliano Bubenick [mailto:bubephp@yahoo.es] Sent: November 17, 2000 07:13 AM To: php-general@lists.php.net Subject: [PHP] Sendmail and php4 Hi: I'm trying to send an email whit this function: mail ("any@any_domain.com", "A$sesion_id", "$mensaje", "From: $email\nReply-To: $email\nX-Mailer: PHP/" . phpversion()); and the maillog write this Nov 16 19:58:57 av sendmail[6132]: TAA06130: to=any@any_domain.com, ctladdr=nobody (99/99), delay=00:00:01, xdelay=00:00:01, mailer=esmtp, relay=mailer2.prima.com.ar.
