Bug #73485 [Com]: mail() adds a lone CR or LF

Edit report at https://bugs.php.net/bug.php?id=73485&edit=1 ID: 73485 Comment by: mattcoz at yahoo dot com Reported by: sherwoodsports at gmail dot com Summary: mail() adds a lone CR or LF Status: Open Type: Bug Package: Mail related Operating System: All PHP Version: 7.0.X Block user comment: N Private report: N New Comment: I think this is the same as my issue. There seems to be an extra character before the additional headers. For example: mail("to@email.com", "Subject", "Message", "From: from@email.com"); To: <to@email.com> X-PHP-Originating-Script: 0:test.php From: from@email.com From: <from@email.com> An additional From header is added and this causes it to be blocked when sent to gmail addresses. On the other hand, if I put a dummy header before it: mail("to@email.com", "Subject", "Message", "X-PHP-Fix: x\r\nFrom: from@email.com"); To: <to@email.com> X-PHP-Originating-Script: 0:test.php X-PHP-Fix: x From: <from@email.com> This is sent successfully to gmail addresses. My guess is that this is the lone CR or LF that is causing his emails to fail. I have one server running 7.0.10 that is affected and one running 5.3.13 that is not affected, which matches his experience.

Changing affected PHP version to 7.0.X. ------------------------------------------------------------------------ [2016-11-10 02:22:15] sherwoodsports at gmail dot com Description: ------------ Mail sent with the mail() function in PHP 7.0.9 or 7.0.11 results in a 550 error from mail servers that does not manifest in mails sent with the mail() function in PHP 5.3.24. The situation results in the receiving mail server to throw the following error during the DATA transmission of the mail message: 550+5.6.0+Lone+CR+or+LF+in+headers+(see+RFC2822+section+2.2) SMTP servers vary as it is a configuration issue to block incoming mail that exhibits this issue. The fix is likely to compare output of mail() for 5.3.24 vs. mail for 7.0.9 or 7.0.11 and resolve the "extra" CR or LF character addition. Expected result: ---------------- Sending from 5.3.24 (to server which identifies issue): 2016-11-10 00:11:35 173.203.187.1 OutboundConnectionResponse SMTPSVC1 xxxx - 25 - - 220+mx1.emailsrvr.com+ESMTP+-+VA+Code+Section+18.2-152.3:1+forbids+sending+spam+through+this+system 0 0 99 0 16 SMTP - - - - 2016-11-10 00:11:35 173.203.187.1 OutboundConnectionCommand SMTPSVC1 xxxx - 25 EHLO - xxxx 0 0 4 0 16 SMTP - - - - 2016-11-10 00:11:35 173.203.187.1 OutboundConnectionResponse SMTPSVC1 xxxx - 25 - - 250-smtp5.gate.iad3a.rsapps.net+says+EHLO+to+xxx.xxx.xxx.xxx:60802 0 0 65 0 47 SMTP - - - - 2016-11-10 00:11:35 173.203.187.1 OutboundConnectionCommand SMTPSVC1 xxxx - 25 MAIL - FROM:<name@domain.com>+SIZE=740 0 0 4 0 47 SMTP - - - - 2016-11-10 00:11:35 173.203.187.1 OutboundConnectionResponse SMTPSVC1 xxxx - 25 - - 250+2.1.0+Ok 0 0 12 0 172 SMTP - - - - 2016-11-10 00:11:35 173.203.187.1 OutboundConnectionCommand SMTPSVC1 xxxx - 25 RCPT - TO:<sendtoname@sendtodomain.com> 0 0 4 0 172 SMTP - - - - 2016-11-10 00:11:35 173.203.187.1 OutboundConnectionResponse SMTPSVC1 xxxx - 25 - - 250+2.1.5+Ok 0 0 12 0 219 SMTP - - - - 2016-11-10 00:11:35 173.203.187.1 OutboundConnectionCommand SMTPSVC1 xxxx - 25 DATA - - 0 0 4 0 219 SMTP - - - - 2016-11-10 00:11:35 173.203.187.1 OutboundConnectionResponse SMTPSVC1 xxxx - 25 - - 354+3.0.0+continue.++finished+with+"\r\n.\r\n" 0 0 46 0 250 SMTP - - - - 2016-11-10 00:11:35 173.203.187.1 OutboundConnectionResponse SMTPSVC1 xxxx - 25 - - 250+2.0.0+Ok:+queued+as+D4/38-19322-24BB3285 0 0 44 0 468 SMTP - - - - 2016-11-10 00:11:35 173.203.187.1 OutboundConnectionCommand SMTPSVC1 xxxx - 25 QUIT - - 0 0 4 0 468 SMTP - - - - 2016-11-10 00:11:35 173.203.187.1 OutboundConnectionResponse SMTPSVC1 xxxx - 25 - - 221+2.3.0+smtp5.gate.iad3a.rsapps.net+closing+connection 0 0 56 0 484 SMTP - - - - Actual result: -------------- Sending from 7.0.11 (to server which identifies issue): 2016-11-10 00:00:00 173.203.187.1 OutboundConnectionResponse SMTPSVC1 xxxx - 25 - - 220+mx1.emailsrvr.com+ESMTP+-+VA+Code+Section+18.2-152.3:1+forbids+sending+spam+through+this+system 0 0 99 0 16 SMTP - - - - 2016-11-10 00:00:00 173.203.187.1 OutboundConnectionCommand SMTPSVC1 xxxx - 25 EHLO - xxxx 0 0 4 0 16 SMTP - - - - 2016-11-10 00:00:00 173.203.187.1 OutboundConnectionResponse SMTPSVC1 xxxx - 25 - - 250-smtp52.gate.iad3a.rsapps.net+says+EHLO+to+xxx.xxx.xxx.xxx:60785 0 0 66 0 47 SMTP - - - - 2016-11-10 00:00:00 173.203.187.1 OutboundConnectionCommand SMTPSVC1 xxxx - 25 MAIL - FROM:<name@domain.com>+SIZE=743 0 0 4 0 47 SMTP - - - - 2016-11-10 00:00:00 173.203.187.1 OutboundConnectionResponse SMTPSVC1 xxxx - 25 - - 250+2.1.0+Ok 0 0 12 0 78 SMTP - - - - 2016-11-10 00:00:00 173.203.187.1 OutboundConnectionCommand SMTPSVC1 xxxx - 25 RCPT - TO:<sendtoname@sendtodomain.com> 0 0 4 0 78 SMTP - - - - 2016-11-10 00:00:00 173.203.187.1 OutboundConnectionResponse SMTPSVC1 xxxx - 25 - - 250+2.1.5+Ok 0 0 12 0 140 SMTP - - - - 2016-11-10 00:00:00 173.203.187.1 OutboundConnectionCommand SMTPSVC1 xxxx - 25 DATA - - 0 0 4 0 140 SMTP - - - - 2016-11-10 00:00:00 173.203.187.1 OutboundConnectionResponse SMTPSVC1 xxxx - 25 - - 354+3.0.0+continue.++finished+with+"\r\n.\r\n" 0 0 46 0 156 SMTP - - - - 2016-11-10 00:00:00 173.203.187.1 OutboundConnectionResponse SMTPSVC1 xxxx - 25 - - 550+5.6.0+Lone+CR+or+LF+in+headers+(see+RFC2822+section+2.2) 0 0 60 0 172 SMTP - - - - 2016-11-10 00:00:00 173.203.187.1 OutboundConnectionCommand SMTPSVC1 xxxx - 25 QUIT - - 0 0 4 0 187 SMTP - - - - 2016-11-10 00:00:00 173.203.187.1 OutboundConnectionResponse SMTPSVC1 xxxx - 25 - - 221+2.3.0+smtp52.gate.iad3a.rsapps.net+closing+connection 0 0 57 0 203 SMTP - - - - ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=73485&edit=1
