Some e-mail messages bounce with the code 554 5.7.1 <[email protected]>: Recipient address rejected: 300
I've recently successfully sent messages to these recipients and suspect this error is due to some issue at the domains' mail servers. A web search turns up a couple of examples of Recipient address rejected, but with text and not with '300.' Where can I find an explanation of this particular error message?
