After lots of debugging I found out, that my client was using a Microsoft IIS server. The servers mailhost obviously had a problem with with the phpmailer class Machform is using. The particular problem was, that phpmailer is using a \n line ending. Microsofts mailhosts rejects those email because it can only deal with \r\n line endings in email headers. So I edited /lib/class.phpmailer.php and changed line 259 of that file into:</p> <p><code>var $LE = &quot;\r\n&quot;;</code></p> <p>For some reason I had to additionally hard-code the senders adress in the function MailSend() adding a $this-&gt;sender ="sender@foo.bar" after $toArr = split(',', $to); at line 468, because otherwise $this-&gt;sender was empty and thus the mail() function not executed.</p> <p>Having made those two changes, everything went smooth. </p> https://www.machform.com/forums/topic/error-sending-email-language-string-failed-to-load-instantiate#post-11746 Sun, 03 Apr 2011 12:51:47 +0000 yuniar 11746@https://www.machform.com/forums/ <p>Ok, so by default when sending an email the script simply call the mail() function which is available within PHP. </p> <p>In your case, the mail() function is not working for some reason. It might be being disabled by your host or the mail agent on your site is down. I suggest to contact your hosting tech support to know the actual reason.</p> <p>To configure your machform to use SMTP, simply edit these lines:</p> <pre><code>define(&#39;USE_SMTP&#39;,false); //set this to &#39;true&#39; to use SMTP define(&#39;SMTP_HOST&#39;,&#39;localhost&#39;); define(&#39;SMTP_PORT&#39;,25); define(&#39;SMTP_AUTH&#39;,false); //if your SMTP require authentification, set this to &#39;true&#39; define(&#39;SMTP_USERNAME&#39;,&#39;YOUR_SMTP_USERNAME&#39;); define(&#39;SMTP_PASSWORD&#39;,&#39;YOUR_SMTP_PASSWORD&#39;); define(&#39;SMTP_SECURE&#39;,false);</code></pre> <p>change the values on the right column of the define() above with the SMTP server details provided by your host.</p> <p>Here's an example configuration using Gmail SMTP:</p> <pre><code>define(&#39;USE_SMTP&#39;,true); //set this to &#39;true&#39; to use SMTP define(&#39;SMTP_HOST&#39;,&#39;smtp.gmail.com&#39;); define(&#39;SMTP_PORT&#39;,587); define(&#39;SMTP_AUTH&#39;,true); //if your SMTP require authentification, set this to &#39;true&#39; define(&#39;SMTP_USERNAME&#39;,&#39;example@gmail.com&#39;); define(&#39;SMTP_PASSWORD&#39;,&#39;mypassword&#39;); define(&#39;SMTP_SECURE&#39;,true);</code></pre> https://www.machform.com/forums/topic/error-sending-email-language-string-failed-to-load-instantiate#post-11745 Sun, 03 Apr 2011 03:59:41 +0000 gydesign 11745@https://www.machform.com/forums/ <p>Can you be more specific on what is wrong with the PHP mail function?</p> <p>And how do I configure the machform to use SMTP server? </p> https://www.machform.com/forums/topic/error-sending-email-language-string-failed-to-load-instantiate#post-11743 Sat, 02 Apr 2011 19:32:49 +0000 yuniar 11743@https://www.machform.com/forums/ <p>That error message indicate that the PHP mail function on your server is not running properly.
