Our mail server is running CentOS 5.3. I configured postfix with maildrop as the MDA. I had to deal with a strange issue : a user
sent an email to an alias, which resolves into several internal addresses. One of these addresses had its mbox filled up (reached
the mailbox_size_limit); so maildrop reported a 0x19 error code to postfix, who kept the mail in its queue, and repeatedly resent
the email : thus every member of the alias list received many copies of this email, except of course the one with the filled mbox.

Is there a way to configure postfix so that it does not resend the email to the recipients who do not report any error ?
