That's quite difficult error to induce. It's a conflict in
address usage between the socket being used and some other
process.

Is there anything unusual about the system you are running?
Multiple MTAs active, perhaps? Or malware doing their
own mailsending...

We might need to see debug for this, but I'd guess
it's on the "connect" syscall being done by the transport.

It gets queued because the attempt to send it failed.
That part is expected given the earlier error.
