[fetchmail] FectchMail and qmail/vpopmail and format.

Hi all,

 my name is Giuliano and I write from Italy.

 I writing because I have the simple questions:

 1. I use fetchmail 5.9.13 with qmail1.0.3/vpopmail5.2.1/qmailadmin1.0.2
and sqwebmail 3.3.6.

 I don't understand the relation "fecthmail <-> vpopmail", and so if I
use the /root/fetchmailrc file
 with 710 permission is right or with vpopmail is necessary another file
?

2. If I use the Maildir format, fetchmail is right or is necessary set
qmail with the Mailbox format ?

 Thanking in advance and sorry for my english.

Pellegrini Giuliano.
