Pegasus-compatible mailbox?

["Alexey Lobanov" <LISTMAN@cpr.cor.neva.ru>]

Hello.

My intention now is to make well-known freeware mailer Pegasus Mail 
working with Unix machine over Samba LAN service. It seems rather 
stupid to retrieve mail by POP3 every minute (with unencrypted 
passwords!) storing it back to same LAN server. Unfortunately, Pegasus 
can't parse Unix-style mailbox: it wants every new message being in a
separate file in some (easy-configurable) directory.

The clear solution is to change "mailbox" transport. Modified mailbox 
must store new messages not to appendable file /var/mail/user but to 
a directory (i.e., /home/user/mail/<random>.cnm).

A weak hope: does anybody know about ready solution?
