who owns subdirs of domains?

[Mate Wierdl]

So I run, as root in ~vpopmail/bin,

./vadddomain a.b.c

Who is supposed to own 

~vpopmail/domains/a.b.c

? Should I add the a.b.c (/etc/passwd) user first?

 (I have installed v 4.9.6 from rpm, and it makes the fixed
 nonexistent uid 521 to own all subdirs of ~vpopmail/domains/).

Thx
Mate
