That why I said not just if vpopmail is using a sql backend.  Compiling 
valias is a configuration option in vpopmail.  What Bill Shupp 
recommended in an earlier mail was to automatically detect whether 
vpopmail was compiled with valias support, so that a configuration 
directive is not needed.

(and I suggested that there maybe be a configuration option to override 
that setting in the case that someone compiled vpopmail with valias 
support but did not want to use valias with qmailadmin).

I'm not following.  A mass conversion == all domains, or a mass 
conversion == all .qmail files in a domain to valias?

I don't know if it would matter.  If they didn't know about vcalias, 
then new aliases would be created with valias.  Edited aliases would be 
recreated anew with valias... so the conversion process could happen 
over time if they were unaware of vcalias.
