Αντικείμενο: [exim] How to debug R=dnslookup T=remote_smtp defer (99): Cannot assign requested address
I'm seeing mail stuck in the queue with the following. Nearly always
from Yahoo - although yesterday I had three sent to gmail that
returned this until a fourth mail was sent then suddenly all four
mails went thru.

2007-11-28 10:04:03 d.mx.mail.yahoo.com [216.39.53.2] Cannot assign

This is being returned _at the same time_ that I can ping the IP
addresses. I'm not at all clear who is returning the message (me or
Yahoo) and if so - what the message is trying to tell me.

I was wondering if this has anything to do with the previous change
made (setting the outgoing IP for a domain to one of the 6 on the box).

The sending address is rscounselling.co.uk. This has MX

rscounselling.co.uk.    54731   IN      MX      5  
family.chrissearle.org.


Which in turn is

family.chrissearle.org. 801     IN      A       78.47.168.122


And the sending IP set in the remote_smtp transport is (from /etc/
exim4/interfaces)

rscounselling.co.uk: 78.147.168.122


78.147.168.122 is one of the IP aliases on this box.

It all looks about right to me?

I'm confused :(
