Evolution produces massive network traffic with IMAP accounts

[mmalmeida]

Since upgrading to Ubuntu 16.04, Evolution generates excessive traffic with a only few (5-7) imap accounts.

E.g. RX bytes:98361856545 (98.3 GB) for a computer with 5h uptime.

Most traffic seems to be generated when you open any folder.
E.g.:
1. Click on the "Sent" folder
2. Wait for it to finish loading
3. Click on "Inbox"
4. Wait for it to finish loading

about 1GB of traffic generated.

Upon speaking with @mcrha on #evolution, it seems that the following might be related with this abnormal behaviour:

Any news on the incorportation of the upstream fix?
This is a blocker issue (application usage becomes so slow I had to switch to Thunderbird).
