#38091 [Bgs]: when sending mail smtp helo does not use fqdn

ID: 38091 Updated by: ronabop@php.net Reported By: danb1974 at gmail dot com Status: Bogus Bug Type: Mail related Operating System: windows xp pro PHP Version: 5.1.4 New Comment: Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php The windows XP "feature" for domain name resolution apparently gives out a bogus answer. This is an XP bug, not a PHP bug. Additionally, "trashcan2.intranet" is not a FQDN. See: <http://en.wikipedia.org/wiki/FQDN>.

Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php The host name use is the same one as your machine will report if you run ipconfig /all (Host Name value). ------------------------------------------------------------------------ [2006-07-13 09:28:43] danb1974 at gmail dot com Description: ------------ Computer reports "Full computer name: trashcan2.intranet" in my computer properties, computer name tab. Sending mail using mail() functions generates a "helo trashcan2" instead of "helo trashcan2.intranet", which is rejected by a unforgiving smtp server (helo requires fqdn). Reproduce code: --------------- mail('danb1974@gmail.com', 'test', 'message') Actual result: -------------- Warning: mail(): SMTP server response: 504 <trashcan2>: Helo command rejected: need fully-qualified hostname in C:\Temp\php\test.php on line 6 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=38091&edit=1
