Hello everyone!
I was wondering, why my Roundcube instance wouldn't show the quota bar, turns out that there is a problem with detecting IMAP capabilities in the RC code. And looks like I'm not the only one: http://trac.roundcube.net/ticket/1485750
In short, our mail cluster setup doesn't return the full set of IMAP capabilities before the user has been logged in.
Our setup (RC 0.3.1-20091031):
Webmail front-end | mail cluster RC -> imapproxy -> perdition -> courier imap
Here is what an IMAP connection looks like from the webmail box:
root@webmail:/# nc 127.0.0.1 143
- OK IMAP4 Ready dzilna 00021323
C: CAPABILITY
- CAPABILITY IMAP4 IMAP4REV1 XIMAPPROXY
C: OK Completed C: LOGIN rudolfs@sigmanet.lv xxx C: OK User logged in C: CAPABILITY
- CAPABILITY IMAP4rev1 UIDPLUS CHILDREN NAMESPACE THREAD=ORDEREDSUBJECT
THREAD=REFERENCES SORT QUOTA IDLE ACL ACL2=UNION C: OK CAPABILITY completed
But when logging in with roundcube I get the following (using xdebug):
public 'capability' => array 0 => string 'IMAP4' (length=5) 1 => string 'IMAP4REV1' (length=9) 2 => string 'XIMAPPROXY' (length=10)
After a little poking around in the Iloha IMAP library, I came up with this hack:
root@webmail:/var/www/rc# git diff program/lib/imap.inc diff --git a/program/lib/imap.inc b/program/lib/imap.inc index 9d896ff..6df5855 100644 --- a/program/lib/imap.inc +++ b/program/lib/imap.inc @@ -452,6 +452,7 @@ function iil_C_Login(&$conn, $user, $password) { if ($result == 0) { $conn->error .= ''; $conn->errorNum = 0;
}iil_C_ClearCapability($conn); return $conn->fp;
It clears the capability array after a successful login. After logging in with this change I get:
public 'capability' => array 0 => string 'IMAP4REV1' (length=9) 1 => string 'UIDPLUS' (length=7) 2 => string 'CHILDREN' (length=8) 3 => string 'NAMESPACE' (length=9) 4 => string 'THREAD=ORDEREDSUBJECT' (length=21) 5 => string 'THREAD=REFERENCES' (length=17) 6 => string 'SORT' (length=4) 7 => string 'QUOTA' (length=5) 8 => string 'IDLE' (length=4) 9 => string 'ACL' (length=3) 10 => string 'ACL2=UNION' (length=10)
And the quota bar is working. Also this bug could be responsible for the IMAP SORT feature not working on my setup...
Your thoughts?
