I am experimenting to use Dovecot as an IMAP proxy to GMAIL server. I would like configure my localhost as an Dovecot IMAP proxy and trying to access my GMAIL using the Thunderbird email client. Please share the steps to configure and access my mails from GMAIL server

but what is the benfit?

you can configure encryption and whatnot different but that does not change the connection between your proxy and the final destination - the weakest part stays as problem independent what you do in the middle of the connection
