* 檢查 PHP 模組是否安裝 OpenSSL {{kbd | key =<nowiki> php -r "phpinfo();" | grep -i "OpenSSL support"</nowiki> }} 或 {{kbd | key =<nowiki> php -i | grep -i OpenSSL</nowiki> }} for {{Linux}}
預期結果：
<pre>
OpenSSL support => enabled
</pre>

* SELinux設定 [http://www.lahory.com/phpmailer-smtp-error-failed-to-connect-to-server-permission-denied-13/ PHPMailer SMTP -> ERROR: Failed to connect to server: Permission denied (13) | Lahory]

預期結果：
<pre>
# getsebool httpd_can_sendmail
httpd_can_sendmail --> on
# getsebool httpd_can_network_connect
httpd_can_network_connect --> on
</pre>

非預期結果：
<pre>
# getsebool httpd_can_sendmail
httpd_can_sendmail --> off
# getsebool httpd_can_network_connect
httpd_can_network_connect --> off
