[vchkpw] .dir-control - Please tell me this about it
Does the hashing that is used by .dir-control depend at all on the actual domain name? For example, if it came up with a hashed directory structure in which to put foobar.com, would it matter if I went in to /var/qmail/users/assign, and changed the name of the domain to somethingelse.com, and then of course changed the directory name from foobar.com to somethingelse.com. Would this be a problem? My problem is I am trying to migrate a bunch of domains (600+) from my own hash style, into vpopmails native .dir-control hash style. So my plan goes something like this: I create a dummy domain test.com I create all the accounts under test.com just like the domain I am trying to move over I then move all the Maildirs into test.com and then change the name from test.com to the domain I was moving I am thinking this should work, but not sure if .dir-control cares what the name is of the domain, or if the hash has nothing to do with the structure of the domain name.

If you use MySQL it will matter as the dir hash info is stored under the domain name. If you do not use MySQL, I would think that you would be ok. The new .dir-control will be correct for the number of users/hashing. The .dir-control file does not have any domain information inside. vpopmail cares not one wit about the name of the domain it is hashing.

Doesn't dir-control begin to hash domains too once you hit a certain number? That is all the same mechinism right, .dir-control, that does both the domain hashing and then username hashing?

Re: [vchkpw] .dir-control - Please tell me this about it
I under stand that, but I guess what I am asking is, the hashing algorithm that vpopmail uses, to decide how to name its directories, is it linked to the name of the username/name of the domain, to the extent that if I change the domain name (or username) but keep the hashing the same, is that going to make bad things happen?

Correct, but the .dir-control file still doesn't keep track of which domain is hashed where, only how many hash dir are created, how deep they are, and what dir is currently in use. It doesn't seem to matter hashing users or domains. It seems to me it works exactly the same what and stores exactly the same information. Think of the .dir-control file more as a tally of what hash dirs have been created, and which one is currently is use. It doesn't seem to do much more.

Again, think of it as a tally of the hashed dirs that exist below the .dir-control file. It only seems to care about the dirs underneath it. I do not belive the hashing code is aware of anything other than it's own path. Create a test domain with your old system and give it a try. I have been trying to get my arms around the dir-control issue for a while, though I don't code C, I don't think the hashing cares what your domain name is.
