Updating: args = username_format=%Ln
under userdb did not fix my issue.
My server still rejects incoming emails with uppercase username e.g. USERNAME@tld.
In /etc/dovecot/conf.d/auth-passwd-file.conf.ext, before I updated with your suggestion i.e. %Ln, I had:
passdb { driver = passwd-file args = scheme=CRYPT username_format=%u /etc/dovecot/users }
userdb { driver = passwd-file args = username_format=%u /etc/dovecot/users
I updated to
passdb { driver = passwd-file args = scheme=CRYPT username_format=%u /etc/dovecot/users }
I think you need to update both places, so that your username and password checks are done with lowercase usernames.
userdb { driver = passwd-file args = username_format=%Ln /etc/dovecot/users
FYI after I updated and tested sending an email with uppercase username again, I ran
# systemctl reload dovecot postfix
also
# dovecot reload
What else can I try?
I tried args = username_format=%Lu too, in vain.
PS thanks for pointing that I should look at username_format rather than auth_ username_format
