A mail I sent (Date: Tue, 31 Jan 2017 15:23:24) appears below the reply (Date: Tue, 31 Jan 2017 15:23:07) I got to it.
Geary should use the headers Message-ID and In-Reply-To (https://tools.ietf.org/html/rfc5322#section-3.6.4), if available, to order mails correctly. The Date header isn't reliable enough.
Hmm, this is a good idea, thanks for the suggestion.
This comment from Bug 713319 might be worth looking into:

GNOME is going to shut down bugzilla.gnome.org in favor of gitlab.gnome.org.
As part of that, we are mass-closing older open tickets in bugzilla.gnome.org
which have not seen updates for a longer time (resources are unfortunately
quite limited so not every ticket can get handled).
If you can still reproduce the situation described in this ticket in a recent
and supported software version, then please follow
and create a new ticket at
Thank you for your understanding and your help.
