[Dovecot] New log entries with 2.0.19?
I just upgraded my Ubuntu server from 11.10 to 12.04.1 and that upgraded
Dovecot to 2.0.19. For some reason I'm getting a lot more (5 times)
disconnect in IDLE and inactivity time outs. I'm using only IMAP with
two users. Both users access the server from multiple devices, phone,
tablet and desktop computer. I had previously set the
max_userip_connections to 20 and rarely got the following limits
exceeded message. That's probably being triggered when we are both home
and using all of our devices on the same network. I've now changed it
to 40 and we'll see how that does.
The other is the IDLE and inactivity timeouts. I don't really
understand how IDLE works and I couldn't find an inactivity timeout
setting to play with. There are at this second 32 imap or imap-login
processes running with only two phones and one desktop running. That's
a few more than before the upgrade but not a lot.
- Dovecot Begin
Dovecot limits exceeded:
max_userip_connections: penny from 216.240.58.138 to
216.240.58.140: 56 Time(s)
Dovecot disconnects:
Disconnected in IDLE: 485 Time(s)
Inactivity: 343 Time(s)
no auth attempts: 14 Time(s)
no reason: 21 Time(s)
Everything seems to be working OK so maybe I should just not worry about it?
Thanks,
knute...

[Dovecot] dovecotadm error
When I use the following command:
doveadm expunge -A mailbox Junk savedbefore 28d
I get:
doveadm(root): Error: User listing returned failure
In the mail log file it says:
dovecot: auth-worker(18549): Error: sql: Iterate query failed: Table
'system.users' doesn't exist (using built-in default iterate_query:
SELECT username, domain FROM users)
However this is setup:
dovecot-sql.conf:
iterate_query = SELECT username AS user FROM accounts
though I have had to comment the following from dovecot.conf:
#iteratedb {
# args = /usr/local/etc/dovecot/dovecot-sql.conf
# driver = sql
#}
because it errors on dovecot start up.
I have already spent a bit of time on the Dovecot website and Google
trying to find an answer. I want to get the expires plugin working.
Any leads please?

Of course in IMAP a mail deletion is often a copy+mark as deleted with the expunge happening sometimes later.

Interactions via Dovecot IMAP/POP3 that lower the mailbox usage, for example the user popping, or deleting mail from the mailbox would trigger Dovecot to unlink the file.

POP/IMAP logs the user in and Dovecot proxies it.

Dovecot has no SMTP proxy (currently). And anyway Postfix doesn't use SMTP to
do authentication, Postfix authenticates using Dovecot's internal protocol,
which replies that Postfix should do the proxying, which it of course doesn't
do.

Make Postfix authenticate against the backend Dovecot server. You'll need to
setup service auth { inet_listener } to some port for it.

The filenames in IMAP's BODYSTRUCTURE reply probably get truncated somewhere around 8192 bytes (then again, maybe not, depends on the encoding I think). And in any case not all IMAP clients use BODYSTRUCTURE.

But in Dovecot POP3 client or the POP3 server? Apparently either Dovecot sends an empty line after RETR or the server thinks Dovecot sends it. Can you get the actual TCP traffic logs? and/or set pop3c_rawlog_dir and see if it's there.

[Dovecot] Length of attachment filenames
Hi there, I have a beginners question to Dovecot: does it have a restriction on the supported length and character encodings of filenames of attachments? Can filenames be arbitrary large?

[Dovecot] Possible mbox corruption if mail is saved with wrong Content-Length header (2.1.6)
One of our users likes to delete attachments from his mails. He is using
roundcube and we installed a plugin for that.
He reports that from time to time one of his mails gets corrupted (cut
off in the middle).
I could verify there is something wrong in the logs:
imap(x1234567): Error: Cached message size larger than expected (6796 > 2844)
imap(x1234567): Error: Corrupted index cache file
/net/mbx3/disc2/home/85/x1234567/Index/.imap/Sent/dovecot.index.cache: Broken
physical size for mail UID 5001
imap(x1234567): Error: read(/net/mbx3/disc2/home/85/x1234567/Mail/Sent) failed:
Input/output error (FETCH for mailbox Sent UID 5001)
imap(x1234567): Info: Disconnected: Internal error occurred. Refer to server
log for more information. [2012-08-23 00:00:49] in=1124145 out=1324791
I had a look at the plugin and it works by duplicating the message and
leaving out the attachment(s). The headers are also duplicated,
including Content-Length. I've fixed that in the plugin, (don't know yet
if it helps), but I think it shouldn't cause such breakage in dovecot.

Re: [Dovecot] Imap Ghost folder
Hi!
Still noone?
strange...this must be some easy thing to solve if you're familiar with
dovecot, i thought.
Anyways, thanks for any help

And i didn't filter into autocreated folders yet. For now, i created
only one sieve rule, that filters into an folder i created manually.
Thank you very much for your help

Sorry, but you forgot to post your complete doveconf -n output
and how to exactly reproduce this.
http://s12.postimage.org/z0n82k2u5/bjddgefg.jpg (Thunderbird)
I'm getting the same result when SIEVE sorts Messages into autocreated
subfolders inside of folders which do not exist. So it's probably
not a ghost folder, it is just an intermediate folder
which does not exist itself, but contains existing subfolders.
This forces your mail client to display the folder in the tree:
INBOX exists (black)
INBOX/foo does not exist (grey)
INBOX/foo/bar exists (black)
HTH and Regards
