The only email reputation and deliverability service with a money-back guarantee! (‘SMTP’ stands for Simple Mail Transfer Protocol.) First, here is a list of SMTP codes and error codes, and what each message is supposed to say and mean: 211 – A system status message. (on their side) 452 – The command has been aborted because the server has insufficient system storage.
Anybody who sends email has seen them, in one form or another – those SMTP error codes, often returned in bounced email, such as “550 Requested action not taken: mailbox unavailable” or “550 5 2 1 mail from refused spam site.” These are often in response to SMTP commands that have ‘gone wrong’ between your email server that sent the email, and the receiving email server that is unable to deliver it (or refuses to deliver it) for some reason. Unfortunately, many receiving systems seem to mix and match these error messages, rather than adhering to the prescribed code messages.

421 Validating Sender doesn't sound like an error on Exchange ! Richard Here is a copy of one of the delay headers, actual email addresses removed.
The server is our spam filtering service, Spam Soap.
Emails from the same external sender and same internal recipient will be randomly bounced/delayed.
But the problem is only reported by a select few external senders/domains.
We are running Exchange Server 2003 and SMTP on our single domain controller, which is quite powerful and seems to handle the other 1000 emails a day without incident.
We have a Net Gear FVS318 router/firewall with NAT and port 25 forwarding enabled from our spam filtering service's IP range.
I've tried everything I can think of, so please skip the obvious unless its part of a methodology. Example of delay: Subject: Warning: could not send message for past 4 hours ========================== does this effect users or domains ? is it everyone from or does [email protected] but [email protected]?Tags: Adult Dating, affair dating, sex dating
