2.4 Error: login_trusted_networks: Invalid network '::1'

10 Apr 2025


      Good afternoon,
With this line added to the default dovecot.conf:
login_trusted_networks = ::1
I get this error:

Version 2.4.1
Works with 2.3.21.1 and many versions before.
It complains with any IPv6 address in login_trusted_networks.
