Evolution/Evolution-data-server ignores the port specified in the CardDav address book settings. The default port is always used. This bug has been fixed a long time ago. Details: https://bugzilla.gnome.org/show_bug.cgi?id=633332 In the bug report above there are two patches, one for evolution and one for evolution-data-server. The patch for evolution seems to be applied in the current stable version (2.32.3-r1), but the patch for evolution-data-server is _not_ applied. I tested the patch from the upstream bug report for evolution-ds and this solved the problem. Please add the patch to the ebuild of evolution-ds. Reproducible: Always Steps to Reproduce: Add a CardDav addressbook with non-standard port.
This is fixed in 3.8.4
