Dear Maintainer,

Using radicale dovecot auth on Trixie fails during handshake with Dovecot 2.4 with the following error:

Radicale configuration:

  [auth]
  type = dovecot
  dovecot_connection_type = AF_UNIX
  dovecot_socket = /run/dovecot/auth-radicale

Related Dovecot config:

  service auth {
    unix_listener auth-radicale {
      mode = 0660
      user = radicale
      group = radicale
    }
  }

The handshake has changed in Dovecot 2.4 with Dovecot Auth protocol v1.3
https://doc.dovecot.org/2.4.1/developers/design/auth_protocol.html

This is a known issue in upstream: https://github.com/Kozea/Radicale/issues/1878

The upstream fix checks and handles Auth protocol version v1.3.
Therefore it seems to be backward compatible.
Upstream commit: https://github.com/Kozea/Radicale/commit/b46916fca9a835b13015e798758bdb13201dd07b

The fix was released with Radicale 3.5.7: https://github.com/Kozea/Radicale/releases/tag/v3.5.7

I successfully backported the patch to Radicale 3.5.3-1 and it works for me.

Could you please ship the bugfix with a point-release so that it becomes compatible with Dovecot?

Thanks you for maintaining and providing Radicale packages.

Yours, Steffen

Hi,

it seems my DMARC reject policy caused mails from debian bug tracker
being rejected. There is a known issue with dmarc reject policies and
the debian bug tracker.

This mail is a ping to raise awareness for the topic for anyone
affected. The status of the bug is still the same.
Sorry for your inconvenience.
