Hello Jud,
Letterrip can't be in the business of trying to interpret the english text
of the error code. We would never succeed at it.
In reference to the discussion on server response: "554 this mail box is full" and your response.
I agree that you can't rely on the english text because it constantly changes. But you should be able to rely on the error codes, since they are supposed to be governed by RFCs.
This from rfc1893 regarding enhanced mail system status codes. http://www.faqs.org/rfcs/rfc1893.html
Here's what a 544 should mean...
5.X.X Permanent Failure
A permanent failure is one which is not likely to be resolved by
resending the message in the current form. Some change to the
message or the destination must be made for successful delivery.
X.5.X Mail Delivery Protocol Status
The mail delivery protocol status codes report failures
involving the message delivery protocol. These failures
include the full range of problems resulting from
implementation errors or an unreliable connection. Mail
delivery protocol issues may be controlled by many parties
including the originating system, destination system, or
intermediate system administrators.X.5.4 Invalid command arguments
A valid mail transaction protocol command was issued with
invalid arguments, either because the arguments were out of
range or represented unrecognized features. This is useful
only as a permanent error.Using 544 is just plain wrong, because it doesn't relate to the mail box or it's status. Unfortunately, some of the big ISPs: netzero and earthlink appear to be using an RFC from some other planet.
It would be semi-logical to return a 5xx series status code, since the word permanent is only intended that resending right away probably won't help.
They should return a 522 or preferably a 422, since that relates to the mail box condition.
X.2.2 Mailbox full
The mailbox is full because the user has exceeded a
per-mailbox administrative quota or physical capacity. The
general semantics implies that the recipient can delete
messages to make more space available. This code should be
used as a persistent transient failure.Hope this sheds more light on the situation for others who are trying to make sense of the topic of bounce management.
Thanks, Marty

In the past, it was very rare for an SMTP server to report "mailbox full"
during the SMTP transaction. It would typically occur after the fact with a
Delivery Status Notification. Regardless, the 5xx series of SMTP errors are
permanent errors. Mailbox full is supposed to be a transient error and
should be reported with a 4XX SMTP error code.
