Dovecot IMAP default config

Hello, i transfer all my domains to a new server with Centos 7.x and Virtualmin Pro too, and i have a problem, i modify the default config of Dovecot and now my imap clients don’t work (Roundcube for example)

Please, can anybody post the default config of a Webmin -> Servers -> Dovecot IMAP/POP -> Mail Files ??

I modify index and control files location

Thank you

I’m sorry its more danger than i thinking :frowning:

Dovecot its not working and not have POP3 access, i migrate my server this weekend and its not working now, please can anybody share your config of a webmin recently installed ¿???
