XF 2.2 Expected response code 250 but got code "503", with message "503 sender already given "

[MilkyMeda]

I haven't come across any source explaining this error. These are just ordinary notification emails. Does anyone have an idea?

• Swift_TransportException: Email to the.last.ksa007@gmail.com failed: Expected response code 250 but got code "503", with message "503 sender already given "
• src/vendor/swiftmailer/swiftmailer/lib/classes/Swift/Transport/AbstractSmtpTransport.php:457

I have been able to solve this particular sender already given error without getting into detail by stopping transport after every failed attempt. But I don't know the exact reason why it needs to be done like this. I couldn't spend time on it to figure it out. I don't recommend doing this but if you really want, you can try:

1. Go to: src/XF/Mail/Mailer.php
2. Find:
   \XF::logException($e, false, "Email to {$toEmails} failed:");
3. Replace:
   $transport->stop();
\XF::logException($e, false, "Email to {$toEmails} failed:");

Assuming you are getting 503 sender already given error right after some different error.

I also have this same problem..

You don't seem to have this exact error: Sender already given

I just tried to verify your email and failed with reason: MailboxDoesNotExist
You seem to have problems with your email server.

I'm going to resurrect this thread because I am having the same issue. I'm not inclined to make changes to the Mailer.php code, but I'm hoping someone might have some idea where to look in m y configuration/ setup for what might be causing this? Here are the details:

• Swift_TransportException: Email to (redacted)@btinternet.com failed: Expected response code 250 but got code "503", with message "503 sender already given "
• src/vendor/swiftmailer/swiftmailer/lib/classes/Swift/Transport/AbstractSmtpTransport.php:457

Here is the stack trace:

And here is the Request State:

This only happens sporadically so I'm not sure if it's a problem or...? If anyone has an idea what is causing this I'l appreciate hearing your thoughts.
