Swiftmailer SMTP transport rejecting the local IP address

Question

I am trying to send an email using Swift_SmtpTransport, but I am getting the following error:

501 5.5.2 <[:: 1]>: Helo command rejected: invalid IP address

The SMTP server is a remote server, and it works from my production server, but not from my development machine, which runs OS X.

He also didn’t bother to throw an exception; instead, I needed to use the plugin to register to find out why it wasn’t working.

What can I do to use a real IP address?

Answer 1

I made some quotes in the code and found it.

When setting up the SMTP transport, you need to call setLocalDomain (). Using PHP on OS X, this default value is ":: 1", which is rejected by the remote server. I just added a line in my development configuration to set the following:

$transport = Swift_SmtpTransport::newInstance('mail.pantsburger.com', 587); if (SITE_ENV == SITE_ENV_DEV) { $transport->setLocalDomain('[127.0.0.1]'); } 

I think this is also a mistake with Swiftmailer - in fact, it should be an exception for something like this, and not just listing each recipient as a "failure".
