POP3 UIDLs with virtual INBOX and migration from maildir->mdbox
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: So you decide to make the new UIDL format "%f" - to make them

migrating from maildir to mdbox, preserving pop3 UIDL
Hi, I'm trying to migrate from maildir to mdbox while preserving the pop3 UIDL (and the imap UID). The problem is, for maildir we use (for compatiblity with qpopper): pop3_uidl_format = %f Problem is, as soon as I convert that to mdbox, then whenever a client issues the UIDL command via a POP connection, the connection is closed and this error is displayed in the log: Error: UIDL: File

maildir vs dbox?
I'm facing some issues on mdbox based backups. Backups are failing with dbox corruption messages. SiS is the greatest advantage though. However backups integrity is very important. If SiS/Deduplication is not a requirement stick to Maildir. Regards DP -----Original Message----- From: dovecot [mailto:dovecot-bounces at] On Behalf Of Gedalya Sent: 20 April 2018 08:19 To:

qpopper UIDLs and migrating to dovecot/maildir
hi all, I am hoping to convert a 350K user qpopper installation using mbox to dovecot and maildir (pop3 only). many of the users "leave mail on server", and qpopper's UIDL format isn't (yet) supported by dovecot. since the UIDLs have been written by qpoppper to the existing mbox files (and will be preserved when the mboxes are converted to maildir) it would be possible to do

dovecot 1.0.15 upgrading to dovecot 1.1.x or 1.2.x, and POP3 UIDL issue
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

2 maintaining order of pop3 uidl's
Hi there, I've just been experimenting with the latest 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

Problems with POP3 UIDL when migrating from MBOX to Maildir
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

dsync and pop3 migration plugin fails for large inbox due to idle timeout
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
