To properly diagnose the problem, we need a short but complete example script to be able to reproduce this bug ourselves. A proper reproducing script starts with <?php and ends with ?>, is max. 10-20 lines long and does not require any external resources such as databases, etc. If the script requires a database to demonstrate the issue, please make sure it creates all necessary tables, stored procedures etc. Please avoid embedding huge scripts into the report. I run php-fpm using the same version and CapabilityBoundingSet and mail works fine - so we need more details. Since the error is logged by postfix I don't think this is caused by php-fpm, who provides /usr/bin/sendmail on this machine? ------------------------------------------------------------------------ [2019-12-05 14:23:23] ilya at ilya dot pp dot ua Description: ------------ After update to 7.4.0 php-fpm don't send mail via mail()/ In postfix mail log: fatal: inet_addr_local[getifaddrs]: getifaddrs: Address family not supported by protocol nginx log empty. php-fpm.service CapabilityBoundingSet=CAP_CHOWN CAP_SETGID CAP_SETUID What else needs to be added here so php can send mail again? Test script: --------------- protected static function mail($to,$subject,$body) { $from = escape(CONFIG['mail']['name']).' <'.CONFIG['mail']['mail'].'>'; $headers = [ 'MIME-Version' => '1.0', 'Content-Type' => 'text/html; charset=UTF-8', 'Content-Transfer-Encoding' => 'binary', 'From' => $from, 'Reply-To' => $from, ]; return mail($to, $subject, $body, $headers, '-f'.CONFIG['mail']['mail']); } Expected result: ---------------- Send mail Actual result: -------------- fatal: inet_addr_local[getifaddrs]: getifaddrs: Address family not supported by protocol ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=78916&edit=1
