[Dovecot] Switch from courier to dovecot

[Richard G Riley]

I have an courier IMAP server running. To get sib dirs working I had to
rename them all to begin with a period ".".

e.g

Maildir
Maildir/{cur,new,tmp}
Maildir/.account1/{cur,new,tmp}
Maildir/.account2/{cur,new,tmp}
Maildir/.account3/{cur,new,tmp}

etc

If I uninstall Courier and install dovecot, will these "period" dirs be
seen by default?

I am fairly new to this and sometimes it seems that Maildir format
requirements vary a lot depending on client or server.

Thank you for your help.
