From the Dovecot 1.0.1 sample dovecot.conf file: # If you want UIDL compatibility with other POP3 servers, use: # UW's ipop3d : %08Xv%08Xu ... # Note that Outlook 2003 seems to have problems with %v.%u format which was # Dovecot's default, so if you're building a new server it would be a good # idea to change this. %08Xu%08Xv should be pretty fail-safe. #

I recently set up an OpenBSD - Dovecot mail server for a client. Naturally (according to Murphy's Law) they want to use Outlook 2003, pop3s, and leave messages on the server. And just as naturally, the UIDLs don't seem to be working, and when they download mail, they get EVERY email stored on the server, not just the new ones. Other than switching them over to IMAP, I found the

I just installed dovecot 1.0alpha4 on a very busy RHEL4 server with about 1300 users. So far so good, except for the dreaded duplicate emails in outlook for users who use POP3 and have "leave message on server" selected. After searching the archives I found that this is usually related to the UIDL format. The example in the .conf file is this: / # If you want UIDL compatibility

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

Hello, I'm in the process of migrating accounts between two dovecot servers. An old server running ancient 1.0.15 and a new server running 1.2.15. Account migration is going to be gradual and so i would like to use imapsync to move messages and subscriptions from one server to the other. The only problem so far is with POP users. After doing an account migration with imapsync, and

Hello! I am trying to migrate from Teapop to Dovecot. I'm using Dovecot 1.1.14. I need to make use of the X-UIDL header so clients don't download messages they've already received. I have the X-UIDL head in the message. I have pop3_reuse_xuidl(pop3): yes My problem is the X-UIDL in the message is being ignored and Dovecot is still generating it's own. The INBOX is an mbx

Dear List, To migrate a dovecot server from dovecot-1.x to dovecot-2.x, then I wonder if the UIDL format "pop3_uidl_format" setting is required in the configuration file for clients not to re-download the same mails from the migrated mail server. Currently, no UIDL format is set in /etc/dovecot file of the one using dovecot-1.x server which means it is commented out as default like

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 '^]'.

I have a big problem with our cluster, if i read my mail with POP3 client (and check the option, keep a copy on server), every time I read my mail, my client retrive ALL messages an the mailbox !!! I test this with: - Apple Mail 1.0 + 2.0 - M$ Outlook 2000 + 2003 - Thunderbird We use: - Dovecot RC1 - Postfix on Debian Sarge (stable) Can you know this bug ? Or have a workaround ? This function

hi all I have a problem with the conversion of files containing UIDL Courier to dovecot uidl , dovecot version is 1.2.15 , format in dovecot is pop3_uidl_format = %08Xu%08Xv i try any other from available list without success courierpop3dsizelist format /2 920 1290084761 1296206202.H818256P31717.domain.tld,S=57135:2,S 57679 87:1290084761 1296239411.H289216P22896.domain.tld,S=1660:2,S 1694

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 I have Redhat ES4.0 with dovecot-0.99.11-2.EL4.1 installed. Reading a post Outlook Duplicates issue is still killing me, there seems to be asolution to this, I was wondering when this will be available on redhat es40? # Note that Outlook 2003 seems to have problems with %v.%u format which is # Dovecot's default, so if you're building a new server it would be a good # idea to

Hi, When upgrading to Alpha4pre I also changed UIDL format from %08Xv%08Xu to %08Xu%08Xv to be in line with future dovecot default. This caused the following error to happen on about 1% of mailboxes: file ostream-file.c: line 370 (stream_send_io): assertion failed: (fstream->io != NULL) Deleting dovecot-uidlist and indexes fixes this so its more of an FYI really. I always delete indexes on

Hi, I'm migrating accounts from one server with dovecot mbox and pam nss-ldap authentication to a new server with dovecot maildir and mysql auth (no posix accounts). My problem is the pop3 uidl format on the two servers are different, even though I'm using pop3_uidl_format = %08Xu%08Xv in both configs, I'm always re-downloading left messages on my test runs. Is there a way I could

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

Hi We have been running a dovecot server for some time.. users connect with pop. Now this server is going to be substituted with a new one.. before we used mbox, but now we will move to maildir! I have done some testing transfering the mail with the mb2md script, the conversion works correctly, but users gets duplicates since they selected "keep mail on server" I have googled for the

Best Dovecot devs, We moved from UW-imap&pop3 to Dovecot this morning (~500 accounts) and reduced our traffic from the home directory server to the imap server bigtime: | 22 Nov| 0.1 0.8| 0.0 0.0| 0.4 0.5| 1550.6 42.9| 1557.3 67.9| | 23 Nov| 0.3 1.0| 0.0 0.1| 0.4 0.6| 1331.8 37.3| 1337.2 46.3| | 24 Nov| 0.0 0.4| 0.0 0.0|

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, when the attached mail was stored in a maildir, fetching mail via POP3 lead to multiple delivery of mails in that maildir to the client (Outlook). I replaced the domain with dots. This is the dovecot configuration: --snip-- protocols = imap imaps pop3 pop3s listen = * disable_plaintext_auth = no ssl_cert_file = /etc/ssl/dovecot/server.pem ssl_key_file = /etc/ssl/dovecot/server.key

http://dovecot.org/test/ - Fixed APPEND hanging in some situations. Didn't happen with mail_save_crlf=yes. - Added pop3_uidl_format setting. No need to patch sources anymore if you don't want the default. Does anyone want pop3_uidl_xuidl_header yes/no setting, with fallbacking to pop3_uidl_format if X-UIDL header isn't found? Shouldn't be difficult to do.. - Added
