The forms work fine on any 32bit PC/Laptop, it's only on the 64bit machines. </p> https://www.machform.com/forums/topic/ipv6-smtp-issue-gt#post-18210 Mon, 06 May 2013 21:23:35 +0000 ausbill32 18210@https://www.machform.com/forums/ <p>1. I've got machforms installed on a windows 2008 64bit server.<br /> 2. I've submitted the form on the browser of the 64bit PC test computer 1.<br /> 3. I've tried another PC with 64bit PC test computer 2, same error<br /> 4. I tried utilizing the 64 bit browser on the 2008 server too and I get the same error. </p> https://www.machform.com/forums/topic/ipv6-smtp-issue-gt#post-18199 Sun, 05 May 2013 12:33:27 +0000 yuniar 18199@https://www.machform.com/forums/ <p>Do you mean your machform is installed on Win7 64bit IPv6? or you simply submit the form from there? </p> https://www.machform.com/forums/topic/ipv6-smtp-issue-gt#post-18185 Sat, 04 May 2013 01:17:36 +0000 ausbill32 18185@https://www.machform.com/forums/ <p>1. I've stood up a brand new instance of v3.4 and I'm still getting the same SMTP error<br /> 2. Issue: I data entered a new form entry and I cannot get the form to send via SMTP on my Win7 PC IPv6 with 64bit (see swift_transport error below)<br /> 3. **(the same form(s) work fine on any XP computer with IPv4 32bit)**<br /> 4. When I go and view the entry, I can see that the entry for the Win7 PC is not showing a valid IP address, it's showing 2002:a5b8:2950:.<br /> 5. When viewing the entry, I can forward the entry via email on any XP computer but not any Win7 64bit IPv6 computer.</p> <p>Do you think this IP could be the issue? Any suggestions.</p> <p>Fatal error: Uncaught exception 'Swift_TransportException' with message 'Expected response code 250 but got code "501", with message "501 5.5.4 Invalid Address "' in F:\xampp\htdocs\machform_3.4_test\lib\swift-mailer\classes\Swift\Transport\AbstractSmtpTransport.php:421 Stack trace: #0 F:\xampp\htdocs\machform_3.4_test\lib\swift-mailer\classes\Swift\Transport\AbstractSmtpTransport.php(305): Swift_Transport_AbstractSmtpTransport-&gt;_assertResponseCode('501 5.5.4 Inval...', Array) #1 F:\xampp\htdocs\machform_3.4_test\lib\swift-mailer\classes\Swift\Transport\EsmtpTransport.php(210): Swift_Transport_AbstractSmtpTransport-&gt;executeCommand('HELO [2002:a5b8...', Array, Array) #2 F:\xampp\htdocs\machform_3.4_test\lib\swift-mailer\classes\Swift\Transport\AbstractSmtpTransport.php(322): Swift_Transport_EsmtpTransport-&gt;executeCommand('HELO [2002:a5b8...', Array) #3 F:\xampp\htdocs\machform_3.4_test\lib\swift-mailer\classes\Swift\Transport\EsmtpTransport.php(258): Swift_Transport_AbstractSmtpTransport-&gt;_doHeloCommand() #4 F:\xampp\htdo in F:\xampp\htdocs\machform_3.4_test\lib\swift-mailer\classes\Swift\Transport\AbstractSmtpTransport.php on line 421 </p>
