deferred mode in exim

[John Griffiths <john@capmon.com>]

Hi all,

I'm trying to get a woody box to send email in defered mode (we have a
number of subscribers who pay to recieve our material but on any given
mailout there will be a couple who's DNS server are down delaying the process)

the outgoing mailserver is behind a firewall so it won't be a target for
spam relayers.

as I understand it a line like:

deferred:
  driver = deferred
  transport = remote_smtp

ahead of

lookuphost:
  driver = lookuphost
  transport = remote_smtp

in /etc/exim/exim.conf

might do the trick,

but can anyone advise otherwise?

Thanks

John
