[Evolution] Folder Scanning Behaviour

[Peter Beurle <peter beurle id au>]

I am cleaning up my inbox and moving mail to the archive folder,
received. The IMAP server support QRESYNC. 

When I move a mail from my inbox to the Received folder it triggers a
'scanning of Received folder'. It then takes some time on a WAN
connection to fetch all the UID's. This happens each time I move mail
from the inbox to the received folder.

Snippet from logs,

A00018 OK [READ-WRITE] SELECT completed'
[imapx:A] I/O: 'A00019 UID COPY 136901 Received'
[imapx:A] I/O: '* FLAGS (\Answered \Deleted \Draft \Flagged \Seen
$Forwarded $MDNSent Forwarded $Junk $NotJunk Junk JunkRecorded Non
Junk NotJunk $has_cal)
A00019 OK [COPYUID 19043 136901 137058] UID COPY completed'
[imapx:A] I/O: 'A00020 STATUS Received (MESSAGES UNSEEN UIDVALIDITY
UIDNEXT HIGHESTMODSEQ)'
[imapx:A] I/O: '* STATUS "Received" (MESSAGES 8079 UIDNEXT 137059

[imapx:A] I/O: 'A00021 SELECT Received'
[imapx:A] I/O: '* OK [CLOSED] mailbox closed

[imapx:A] I/O: 'A00022 OK UID FETCH completed'
[imapx:A] I/O: 'A00023 UID FETCH 1:137059 (UID FLAGS)'
[imapx:A] I/O: '* 1 FETCH (UID 1421 FLAGS (\Answered \Seen))'
[imapx:A] I/O: '* 2 FETCH (UID 1422 FLAGS (\Seen))'
[imapx:A] I/O: '* 3 FETCH (UID 1423 FLAGS (\Seen))'
[imapx:A] I/O: '* 4 FETCH (UID 1432 FLAGS (\Seen))'

For the next thousands of mails...

Should QRESYNC be avoiding this continual polling of the received
folder?
