upgrade mail paths (Debian 1:2.4.1)

Dear Dovecot Users

I guess there may be a storm of questions from users of Dovecot on Debian who are upgrading to the latest Debian stable, which uses Dovecot 1:2.4.1 [1] with the concomitant configuration changes.

The issue I have encountered a problem translating my previous configuration for "mail_location" to "mail_path".

The mail_location string returned from my database was

mbox:/home/<user>/Mail/:INBOX=/var/mail/<user>:INDEX=/home/<domain>/Mailindexes/<user>

Reading the mail location docs [2] I'm unclear if the colon separated configuration still works or if the configuration items should be separated into separate fields, presumably:

mail_path
mail_inbox_path
mail_index_path

Thanks for any insight.

Regards, Rory
