Title: 451 please retry later message but it doesn't seem to be retrying
Post by: jah on Wednesday 22 April 2009, 11:03:34 am
We use Endian as our firewall and Exchange behind it as the email server. There is a specific domain using greylisting and whenever we send them email it comes back undeliverable with a "451 please retry later" message. The users never get our email, so it seems the server is not retrying like it should.

Any ideas?

Thanks in advance,

Jamie
