imapc settings have moved away from plugin {} section and mail_location.
Now instead use:mail_location = imapc: imapc_host = imap.example.com #imapc_port = 143 # default #imapc_user = %u # default imapc_password = secret imapc_ssl = no # or imaps or starttls imapc_ssl_ca_dir = /etc/ssl/certs Note the imapc_password change also. If passdb/userdb returned userdb_pass/pass previously, return now instead userdb_imapc_password/imapc_password.
