The problem is probably with you moving the queue directory (which is
a definite no-no, because the filenames in there must correspond to their
inode numbers). Check out queue-fix on qmail-org, it should help at least
one of your problems.

Subject: Moving qmail
servers
I recently tried (unsuccessfully) to replace one of my
qmail servers (Red
Hat Linux 6.2)
by:
1) creating new qmail
server (lets call it mail2)
2) tar'ing up the following
dirs:
/var/qmail/control
/var/qmail/queue
/var/qmail/users
/home/vpopmail/domains
(cause I use vpopmail)
/home/vpopmail/users (cause I use
vpopmail)
3) stopping the qmail processes on mail1 (the qmail
server to be
replaced) and mail2
4) un-tar'ing the files on the
mail2
5) shutdown server mail1
6) rename and re-IP mail2 to
mail1 by editting the
following:
/etc/sysconfig/network-scripts/ifcfg-eth0
/etc/hosts
/etc/sysconfig/network
/etc/HOSTNAME
7)
bring up new qmail server (now known as mail1)
The hopes were by
following this pattern I would:
* experience very little down time
*
if a problem occured, all I had to do was simply shutdown new
qmail
server and bring up old one
* no DNS changes to make
The only
problem was it didn't work. Everything seemed to come up OK.
Email
could be queued up
but would not get delivered UNTIL I bounced
the box. In this case all the
mail that was queued
up got sent but
any new mail still experienced the problem (it would queue
up but would
not be
delivered until I rebooted the box).
After a few
frustrating attempts at fixing, I simply shut the new box down
and
brought
up the old one.
The only thing I could guess was the
when qmail is compiled, I remember the
instructions were specific about
making sure (hostname -f) responded with
the
FQDN. Since at the time
the box was compiled, the FQDN of the
new qmail server was
mail2.domainname.com, this caused some problem
when I shifted the FQDN
to mail1.domainname.com.
Questions:
Is their a better way to
perform this task?
Did I miss some key task when I renamed and
re-IP'd the new qmail server?
