Dear Dovecot community,
I try to migrate a GMail mailbox to Dovecot using doveadm backup -R imapc:. Since it seems that GMail disabled the login without XOAUTH2, I
cannot figure out how to authenticate dovecot to GMail. Could you point
me in the right direction? Thank you in advance!
Best regards, Jan
Here the commands and config I am using:
# dovecot --version 2.3.19.1 (9b53102964)

# cat gmail.conf !include /etc/dovecot/dovecot.conf
