I actually have two questions. The first one is if anybody has
experience with converting a qmail system from vmailmgr to vpopmail.
We have devised ways of doing it, but if anybody has already done it
and has to do's/don'ts/pointers they came across I would appreciate it
if you would share them.
Not me, sorry.
Second question. We have a lot of domains that resided on our server
and due to directory limitations, can not have all the domains reside
in ~path/vpopmail/domains. Is there any good solutions that people
know of? The only one that we have come up with is to modify the code
to add the domain directories into sublevels (ie
~path/vpopmail/domains/a-e/, ~path/vpopmail/domains/f-n, etc). After
considering this, I realized that this probably would require a lot of
changes in the code which is possible but we're hoping for a shorter
time frame to get it up and going.
I do have some experience on mail conversions, first from a sendmail box
to two vpopmail boxes, then from the two vpopmail boxes to a cluster
behind a MailScanner box. I have some strong opinions on this. Take them
for exactly that, opinions ;^)
Conversions are messy, avoid them, they will give you more heartache
than success. Having inherited the last conversion I would opt for
building a complete new box, configured, setup, tested, before I did
anything else. Then I would script the adding of all accounts onto the
new box. This could be done from a list made of rcpthosts, and
morercpthosts files along with your vpasswd files. vadddomain and
vadduser respond very well to this. Then I would change DNS and roll
your users to the new box in one fell swoop. You could then nfs mount
your old Maildirs onto the new box and script the moving of the users
mail from the old into the new Maildirs.
This will ensure that everything is bright and shiny, nothing is
orphaned, no files are left behind or unconverted. You will be assured
your dir_control, vpasswd, vlimits files are correct. If I had to do it
all again, that is exactly how I would go about it.
