[Evolution] Evolution pinging IMAP gmail

[Ambrogio De Lorenzo <ambrogio de lorenzo alice it>]

Hi all,
I used very hard evolution 2.32.3 with fedora 14, because I didn't
upgrade to the new fedora and evo releases.
In this environment I had some bugs with which I learned to live.

Now I installed a fresh fedora 20 with evolution 3.10.3 and I thought
that some bugs where gone.

I have the same behaviour with gmail imap.
Evo still ping to the server and sometimes it hangs for minutes.
I can't understand why, but that stop a lot of other activities (even
the retrieve of messages from a local imap server).

I read that this question is common on internet but I don't understand
if there is a solution.
Someone can explain to me that?

Bye
 Ambrogio
