XF 1.5 SMTP Connection Refused?


New member
Hi, I'm using Office 365 as my SMTP server because godaddys default email handler is too slow. All the SMTP information is correct but I keep getting a connection refused error.... And I called the host they said it shouldn't be happening here are the error logs if someone could help me that'd be awesome!

Zend_Mail_Protocol_Exception: Email to blueberrygw2@gmail.com failed: Connection refused - library/Zend/Mail/Protocol/Abstract.php:277

I would definitely double check the SMTP settings you entered -- the port specifically.

There is a possibility that your host is explicitly blocking outgoing connections on that port; this practice has certainly been common on residential connections, for example. If there are alternate ports you can use, try them.
Agreed with @Mike. Most of the hosting provider explicitly block the outgoing SMTP ports. Try port 2525 if that works. Else try connecting with your hosting provider to unblock port 25, 587, 2525 for outgoing SMTP connections.
