Package: exim4
Version: 4.63-10
Severity: normal
There is an interesting patch in the current exim-upstream version (4.64)
which fixes delay-problems if a mailserver returned a 4xx for a mailbox.
For a complet description of the problem, see below.
In my situation this causes sometimes huge delays for a single mailbox which
is quite annoying. I wonder if it's possible to backport this to debians exim
version.
>From the exim ChangeLog:
Exim version 4.64
-----------------
PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
runs only) independently of the message's sender address. This meant
that, if the 4xx error was in fact related to the sender, a different
message to the same recipient with a different sender could confuse
things. In particualar, this can happen when sending to a greylisting
server, but other circumstances could also provoke similar problems.
I have changed the default so that the retry time for these errors is
now
based a combination of the sender and recipient addresses. This change
can be overridden by setting address_retry_include_sender=false in the
smtp transport.
