My current Postifx configuration is setup to receive only and I store all received mails in /var/mail/vhosts/example.com/account/ in Maildir format.
Currently I use mutt to read these mails.
Is there any way I could configure Roundcube webmail to browse these mails without installing Dovecot or other IMAP/POP3 handlers? No need to send e-mails, just read only.
