That question hinges on whether or not the bounce should be
considered a permanent or a temporary failure. The bounce itself says
"This is a permanent error."
Agreed. However I believe the permanent or temporary nature that the
bounce is speaking of is on the SMTP level, thus the sending server
should not try to send this given message again. I think it is a flaw
to extend this SMTP meaning up to actual future (different) message
delivery.
I disagree. I think it is likely to be an abandoned account, but in
any case, with default bounce processing settings, The user's
delivery won't be disabled until a bounce like this is received on 5
separate days.
Possibly. My experience with my customer shows that people are likely
to hit their quota over a weekend or a vacation. When they come back
the following week (or when ever) and POP all their messages out of
their box, the /temporary/ error is corrected. Granted my experience
may be limited to my customer scope and more than likely does not apply
to someone like GMail or HotMail or Yahoo. I guess it depends on the
customer base.
So probably when we disable the user's delivery after 5 days of
bounces, the disabled notice we send to the user might be accepted,
and with default settings, the user won't be unsubscribed until 3
weeks and two more notices later.
Agreed... as long as there is not < 23 kB worth of email received in the
next 3 weeks. However if the user does not clean out their mail box in
that time this leads credence to the likely hood that the account is
abandoned.
Granted, this could be a user on an extended vacation (over a month),
but in that case, ultimately unsubscribing the user is easy to
reverse and is small penalty for the user's forgetting to disable
list delivery.
True...
Grant. . . .
P.S. I find it interesting that the bounce is eluding to the amount of
space remaining in the account. This is (in my experience) extremely
unusual.
