I believe it is fixed, but not on your version [which is not the current
version]. 3.6.x certainly had some connection management issues, at
least with HTML messages, and especially behind a proxy server.  I have
not need these issues on 3.8.x.

I do not recall ever seeing connection issues regarding LDAP.

Agree.

It didn't cause any problems, and was fine by me.  There are just some
people here you are grumpy about attachments [although they use an
excellent mail client that handles them gracefully ;) ].

If you see constant connection issues and loading of messages for HTML
messages is disabled... I suspect there might be something else wrong in
addition.  It was annoying in 3.6.x, but certainly not debilitating.
Any chance there is an overloaded NAT involved that is prematurely
terminating your connections? [Die NAT Die!  All hail IPv6, our
deliverer!]

Have your tried running with CAMEL_DEBUG enabled and see if that
enlightens you about anything
<https://live.gnome.org/Evolution/Debugging>?

But, seriously, 3.8.x is a *MUCH* better Evolution.  3.6.x Evolution and
GNOME were pretty good. 3.8.x is excellent and very solid.  I know
nothing about Fedora [at this point you would have to drag me away from
openSUSE in chains - it just @*&$&* ^&* WORKS!] but certainly they
provide some reasonable way to update to the latest  * * *STABLE* * *
version of GNOME.  

Did I mention that 3.8.x is the current * * *STABLE* * * version of
GNOME. If I didn't, I should have.
