Do they allow connection to mandrill using port 587? </p> https://www.machform.com/forums/topic/smtp-error-mandrill#post-22987 Tue, 24 Mar 2015 22:21:12 +0000 timmaton 22987@https://www.machform.com/forums/ <p>Hi there</p> <p>We're experiencing some problems with email delivery from the form entries and so I'm trying to use a 3rd party SMTP server (mandrill) to send them instead, however I'm still having problems and now the forms aren't sending at all!</p> <p>I have the following settings setup on the main_settings.php page:</p> <p>SMTP Server: smtp.mandrillapp.com<br /> Use Authentication: Yes<br /> Use TLS/SSL: No (also tried 'Yes')<br /> SMTP User Name: [my_username]<br /> SMTP: [my_password]<br /> SMTP Port: 587</p> <p>However, when I submit a form I get the following error on screen:</p> <p>Fatal error: Uncaught exception 'Swift_TransportException' with message 'Connection could not be established with host smtp.mandrillapp.com [Connection refused #111]' in /home/content/94/8775794/html/machform/lib/swift-mailer/classes/Swift/Transport/StreamBuffer.php:259 Stack trace: #0 /home/content/94/8775794/html/machform/lib/swift-mailer/classes/Swift/Transport/StreamBuffer.php(64): Swift_Transport_StreamBuffer-&gt;_establishSocketConnection() #1 /home/content/94/8775794/html/machform/lib/swift-mailer/classes/Swift/Transport/AbstractSmtpTransport.php(115): Swift_Transport_StreamBuffer-&gt;initialize(Array) #2 /home/content/94/8775794/html/machform/lib/swift-mailer/classes/Swift/Mailer.php(80): Swift_Transport_AbstractSmtpTransport-&gt;start() #3 /home/content/94/8775794/html/machform/includes/helper-functions.php(792): Swift_Mailer-&gt;send(Object(Swift_Message)) #4 /home/content/94/8775794/html/machform/includes/post-functions.php(2624): mf_send_notification(Object(PDO), 17928, 732, 'amex@ircorporat...', Array) #5 /home/content/9 in /home/content/94/8775794/html/machform/lib/swift-mailer/classes/Swift/Transport/StreamBuffer.php on line 259</p> <p>Any help would be greatly appreciated as, we're currently getting complaints from users that they can't submit forms!</p> <p>Many thanks</p> <p>Tim </p>
