I might be stupid to ask this, but I have looked online and in
documentation, so I decided to ask here.
I have a qmail+vpopmail setup, that authenticates through a remote mysql
server. When I take the mysql server down and replace it with a
different box, thats has all the data, users, grants etc
This could be from a number of problems, but most likely, the MySQL version has
changed between boxes, or mysql is in a different place on the machine.
vpopmail takes the mysql include and lib files and compiles them into the vpopmail
binaries.
Changing versions may require recompiling vpopmail.
