We have this configuration:
IMAP server
-----------
IMAP server: UW-IMAP 2007f.404
Default mail folder format: mbx
The server supports the following IMAP capabilities:
IMAP4REV1 I18NLEVEL=1 LITERAL+ IDLE UIDPLUS NAMESPACE CHILDREN
MAILBOX-REFERRALS BINARY UNSELECT ESEARCH WITHIN SCAN SORT
THREAD=REFERENCES THREAD=ORDEREDSUBJECT MULTIAPPEND SASL-IR
LOGIN-REFERRALS AUTH=PLAIN AUTH=LOGIN
Webmail client
--------------
OS: Ubuntu 10.04.3 LTS
Webserver: Apache 2.2.14
PHP: 5.3.2
Horde (horde): 4.0.10
Mail (imp): 5.0.14
Imapproxy: 1.2.6
In order to improve performance, we convert some mailboxes from mbx or
mbox to uw-imap "mix" format.
In the webmail client, if we mark some messages for deletion in
mailbox with mix format, when we purge the mailbox ALL messages are
deleted. This doesn't happen with mbx format.
No problem with other email clients: Thunderbird, Outlook,... Probably
they don't use UID EXPUNGE.
We have done some tests from a telnet session too:

The problem is the IMAP command "UID EXPUNGE 1:*" with mix mailboxes.
If I set an explicit UID it works fine.
Thanks in advance.
