Courier migration to dovecot

[j.emerlik]

Hi,
I'm almost ready to migrate Courier to Dovecot 2.2.31 but I have one
question about home and mail directory.

It's good idea to have same directory form home and mail ?

Which scenerio will be better and why ?

For example:

A)
Home: /home/doamin/user1
Mail: /home/doamin/user1

B)
Home: /home/doamin/user1/home
Mail: /home/doamin/user1

C)
Home: /home/doamin/user1/
Mail: /home/doamin/user1/mail

Thanks & regards,
Jack
