Embracing .99
We're stuck on RHEL 4.x, so we're currently working on a plan to live in
harmony with .99 for another year or so. With that said, the plan is
below. Let me know if you have any other recommendations.
[ ]Convert to high-performance mode vice high-security to reduce overall
resource usage.
[ ]Implement iptables throttling for new connections to prevent denials
of service.

Duplicate Messages, Different X-UIDs?
We're running into an issue where sendmail is only receiving one e-mail,
but after a client accesses the message via IMAP and moves it to another
IMAP folder, the message duplicates but each message has different X-UID
headers. Has anyone ever seen this type of anomaly before? Is it a bad
IMAP client, or a known bug?
Running 1.0.7
Thanks!

dovecot-auth: Too many open files
All,
[version: dovecot-0.99.11-4.EL4.src.rpm]
We recently experienced an issue that prevented all new IMAP logins from
occurring. Although it appears that it was due to running out of
available system file descriptors, I'm still not sure what the true root
cause was as I can't replicate the same error in our test environment.
The system file descriptor max was set at (per `cat

open files
This morning dovecot stopped allowing pop3 logins. In the logs I found
the messages below
Is there a config value for the max open files ?

locking strategies?
Any known issues with these locking strategies? (RHEL 4.x default)
Dovecot:
mbox_locks = fcntl
Procmail
Locking strategies: dotlocking, fcntl()
We're considering moving to all dotlocking after a recommendation from
RedHat, even though we're not using NFS at all.
Thanks!

Message UID Question
I have referred to the wiki and the RFC, but I still can't find the
exact answer I'm looking for. From what I know, Dovecot uses the IMAP
standard of 32 bit integers to uniquely identify messages.
After a message is deleted from the mbox, can this UID ever be reissued
to a new message or is that UID retired? What about after the 2 billion
limit is reached?
Thanks!

upgrade from beta9 to rc1 - lost access to messages and folders
Hello All,
Upgraded a test machine this morning from beta9 to rc1 and lost access to
messages and folders.
an strace on the imap process shows it accessing the home directory, but
not the mail directory. The two queries that I use are:
password_query = SELECT email,crypt as password FROM users WHERE email =
'%u'
user_query = SELECT homedir AS home, maildir AS mail, 1000 AS uid, 1000

Maildir Quota and Trash Folder
Is there an option to instruct the imap_quota plugin to count messages
in the Trash folder as used space?
Thanks,

maildir++ quota bug...
Running RC2 with maildrop and MDA:
dovecot writes a positive quota count, then the negative quota count
on messages delivered with maildrop.
For example,
message #1 arrives via maildrop:
4488236 1
message is deleted via dovecot:
4488236 1
-4488236 -1
This does not happen when the user accesses the message, only when it
is deleted.
The user never gets credit for deleting

pop-3 login delay
We are running Dovecot 1.0.beta9 w/ mysql authentication. Mail
storage is a Network Appliance F810 filer and we are using maildir.
The only issue that we have run into is that pop3 logins take much
longer than imap logins within dovecott and many times longer than a
similar connection with courier-imap. For example, dovecot IMAP and
courier-imap POP3 and IMAP logins take less than 1/2

How limits are set in a scales list
I have a lattice plot that has 4 pages with 4 columns and 8 rows per
page. I wish to have the rows use a separate x-axis since their
ranges are quite different, but I wish to have those same limits used
on each page.
By setting an element of the scales list to something like x = list(limits =

Maildir++ quota - how to handle a full mailbox

the user - which was received. However, when I attempt to move the

QCC and PlotMath question
For some reason, using the qcc package, I'm unable to use the plotmath
notation in the title. Can anyone see what I'm doing wrong?

a <- rnorm(100)
qcc(a,type="xbar.one",title=expression(bar(X)),ylab=expression(CFU/ft^3)

This seems to not let the expression be evaluated, so I tried:

Post-migration questions
I just migrated from courier-imap to dovecot and dovecot is a lot
faster. My only client is webmail on the same server as dovecot. Max
~10 users.
Should I still run imapproxy like I did with courier?
Does dovecot periodically empty the trash folder like courier does?
I reduced the number of processes courier was running to save RAM and
improve performance. Are there any performance tweaks I
