similar to: Question about the pop3 feature "leave messages on server for a certain period of time"

One of our users wants to use POP3 with leave-mail-on-server (LMOS). That's great and works well for most people. But for some reason, they MUA (outlook) downloads messages more than once. As the MUA asks for messages, I'm sure it's Outlook's fault, but I was wondering if there is anything that can be done about this on the servern side, or if anyone knows how to fix Outlook.

hi All, I have a srange problem. Before dovecot there was a courier imap and it worked just fine. The client(s) are the same then before, so I think, this is an server side problem. I have a user with Outlook and he uses pop3 and leaves messages on server. Sometimes the messages get downloaded again, when he starts the outlook. Not all, but 7-9 hours back. uidl format is like it's

Hi Timo, i allready asked about this , and did some fixes , but it isnt working yet ,as far i have a setup like namespace default { # type = private separator = / prefix = "" list = yes # hidden = no subscriptions = yes } namespace virtual { # type = private prefix = "virtual/" separator = / location =

I'm trying to understand what dovecot's behavior will be in a given scenario to see if it will work as a (hopefully better) replacement for the home-grown pop3 server we currently use. User A is on a slow dialup connection, and uses, oh, let's say Outlook, since that's where most of our problems seem to spring from. User A uses outlook to download his mail over pop3. Half

Hi there, I've just been experimenting with the latest courier-dovecot-migrate.pl script and I notice that it favours keeping pop3 UIDL ordering rather than IMAP UID preservation. There is this comment (line 312): # POP3 clients may want to get POP3 UIDLs in the same order always. # Preserve the order even if it causes IMAP UIDs to change. Does anyone have details as to which

Hi, We're upgrading a cluster of servers from v1.0.15 to v1.1.x or v1.2.x. It appears that the UIDL generation mechanism has changed, and thus we'll be getting POP3 dups with users that leave mail on server (which is a nasty practice, I know). From checking the sources, and performing a number of controlled tests in various scenarios, here is the outcome: upgrade from 1.0.15 to

Hi, today I've finished migration from uw-imap daemons to shiny and fast dovecot. With thanks of dovecot my mail server load average drops by factor of ten even with ancient unix mailboxes. ;-) So, the only thing I've discovered is what POP3 uidls are different than ones used in the uw-imap. Luckily, the difference are only in the format string used in uidl response. So, I've

Hi, we're trying to migrate from UW imap 2001a-10, which doesn't seem to use the UIDL format documented in the wiki. It seems to use a 16 character long MD5 hash of something. I've tried configuring Dovecot to do the same but the value comes out differently. The main thing that I can see is getting in the way is that the UIDL format is not documented sufficiently. There is no

I saw a few commits for 2.0.13 that added MAIL_FETCH_POP3_ORDER, but I haven't been able to find any information on how to use it. I'm migrating from a Merak mail server into dovecot and all the email can be copied directly into a Maildir/cur directory. The filenames are just the timestamps. When I check with dovecot pop3, they seem to be randomly ordered. I'm hoping this

Hi ! POP3-RFC (1939) speaks about UIDL command: The unique-id of a message is an arbitrary server-determined string, consisting of one to 70 characters in the range 0x21 to 0x7E, which uniquely identifies a message within a maildrop and which persists across sessions. When I issue an UIDL command (dovecot 0.99.10.9) I get replies like 1 1093990148.1 2 1093990148.2 3 1093990148.3 ... . You see

Greetings, is anybody aware of an extension to POP3 that supports UIDL ranges? It would be very useful for keep-messages-on-server setups (yes, I know, IMAP4 domain) to be able to do UIDL 21-42 to obtain just these 22 UIDs (this would always have to be a multi-line reply, just like UIDL without argument). If such a thing does not exist yet, perhaps a keyword such as "[X]UIDLRANGES" in

Hi, Considering the scenario, where you have some old account with a different POP3 UIDL format and you migrate them to dovecot. So these old UIDLs would be saved to dovecot-uidlist. At some later time you want to introduce a virtual POP3 INBOX like described on: http://wiki.dovecot.org/Plugins/Virtual So you decide to make the new UIDL format "%f" - to make them unique across

Is there some way that message uids can be preserved when converting uw-pop3 mbox mail to dovecot maildir format? We've tried perfect_maildir, mb2md and the convert-tool that comes with dovecot but so far have been unable to preserve the message uids, which for example go from 44333a8500000003 before the conversion to 4434621500000003 afterwards. The quantity of mailboxes involved means

HI All, We have the latest Dovecot 1.1.6 running and I need to migrate some POP3 users over from Courier to Dovecot and would need to convert the courierpop3dsizelist to maintain the UIDs. I just need to confirm that the script (http://www.dovecot.org/tools/courier-dovecot-migrate.pl) only works for Dovecot v1.0 and not for v1.1? As the dovecout-uidlist file that is created (by the script) is not

Dear all i'm planning a transparent migration from a courier server that provides both IMAP and POP3 access to users to a remote dovecot server with both IMAP and POP3 access. I have to migrate about 2500 users for 250 GB of space. I'm using dovecot 2.2.5.4 on debian6 squeeze. To make a transparent migration i have to maintain old IMAP UIDs and POP3 UIDs, so i've read

Timo, There is a problem with the dsync POP3 migration plugin when syncing a large INBOX. What happens is dsync establishes a connection to the POP3 server at the beginning of the sync, but then it sits there idle until it's used to sync the UIDLs. On a very large inbox with many thousands of messages it will be idle for longer than a POP3 server's idle timeout setting. When the UIDL

I have installed rc22 and tried it with my mbox-based mail - fine. Then I converted that mbox to Maildir to see if new feature (saving state without QUIT) works - first run - I get time out. Second run - I get rest of the Maildir scanned and get into mailbox. Fine. but.... # telnet enders2 110 Trying 127.0.0.1... Connected to localhost.localdomain (127.0.0.1). Escape character is '^]'.

Hello, I am in the process of migrating a hosting setup from UW-IMAP to Dovecot. The protocols available to mail clients are IMAP and POP3 both before and after migration. I also wanted to change the mail storage format from MBOX to Maildir. However, at this point I hit a major snag with Dovecot and POP3 UIDL (unique identification listing for POP3 mailboxes). Several of the customers connecting

Hello everyone, in february I posted the mail below[1]. I can now reproduce the problem. When filling up a mailbox with postfix' smtp-source with dozens of identical mails, then it is never possible for me to fetch one single mail out of the mailbox. The process of fetching mail via POP3 always fails. It makes no difference which mail client I use. I have tested KMail, Outlook and
