Dear All I have two mailq's, the primary is running sendmail v8 the secondary is running qmail 1.03. I have just finished configuring a replacement for the new primary which will also be running qmail 1.03. Where I need advice is how best to make the swap and how best to flush the queue on the old box into the new. I had thought of the following; 1:) drop the queue lifetime down on the primary sendmail box to nearing 72hrs (shorter than the RFC advised 120 hrs) to keep the queue as small as possible. 2:) remove the primary mailq, domain mail would then take the next best mx pref and head for the secondary mailq and queue their. 3:) reconfig the old primary (sendmail) with a temporary hostname and IP on the server network. 4:) install the new primary mailq (qmail) which of course would start accepting mail the moment the smtpd daemon is up. NOW the bit thats bothering me. 5:) would the secondary after 60 mins (or send qmail-send an svc -a alarm) then deliver its queue back to the new mailq as it has a lower mx? 6:) would the old reconfigured sendmail also deliver its queue to the new mailq as DNS would give that as the lowest mx pref. All assume the final destination is a MTA on a dial up. Many thanks in advance. Mike [EMAIL PROTECTED]
