Package: postfix-gld
Version: 1.4-3
Severity: wishlist

It has been found that responding with a 450 status code causes some
problems with sites like MSN/Hotmail, Prodigy and various other
senders that appear to be having "weird" retry patterns (sometimes
resulting in bounces) when using code 450 or others. 

Because error code 450 is most commonly used for mailbox lock failure,
many sites seem to treat it as a very short duration failure, and will
retry several times within seconds, and then bounce the mail. They
seem to handle a code 451 more "normally"

It would be nice if postfix-gld had an option to change the code, or
just used 451 instead of 450.

Thanks!
Micah
