Hi, I did some performance testing with dovecot and qpopper, if anyone is interested.. Hardware: Dual Xeon 2.8 with HT enabled (dmesg sees 4 cpu-s), 1 GB RAM, SCSI RAID 1 with 2x Maxtor Atlas 10K V disks. Software: CentOS 4.3, Qpopper 4.08 in standalone mode vs Dovecot 1.0-0_19.rc6, ext3 filesystem Mailbox format Mbox, tested Pop3 with PAM authentication My setup had 15 test users with 15

I am testing migration from Qpopper 4.0.5 and have come across a problem. Dovecot dies while processing UIDL command when accessing malformed Qpopper's mbox which has duplicated "From " separator. Qpopper occasionally makes such header while rewriting mbox. In the attached file, unnecessary "From " at line 3. ---------------- * Dovecot 1.0.0 on Debian 4.0(x86) * ext3

We have an older mail server using qpopper and the mbox format which we need to update to dovecot and maildir format. I have read through the docs on migrating from mbox to maildir, as well as a few nuggets on how to migrate from qpopper to dovecot, and I was wondering if I could get some suggestions on best practices for this specific migration. Would the built in dovecot conversion plugin be a

Hi All, Our test users re-download the mail they've left on the server when they switch from Qpopper to Dovecot. Qpopper includes the X-UIDL header - X-UIDL: X8V"!E)<"!58?"!"9C"! - on read messages. Any suggestions are appreciated. I've included my dovecot configuration. Thank you, Tristan --- Tristan Tristan Goguen CEO, ILAP? T: 416-250-5600 ext. 205 F:

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

Hello, As this is my first post to the list, first and foremost I'd like to thank Timo for writing great software; we've successfully moved to Dovecot for over 10,000 users from UW-IMAP and get great performance. On our overloaded staff POP3/IMAP server, we are looking at replacing qpopper+uw-imapd with dovecot, as an interim before moving them to the main Unix mailstore. The system is

Hello, I have read in lots of places about how I should use pop3_reuse_xuidl = yes to prevent pop3 users having to re-download mail (and duplicate their e-mail) after a migration. This fails with the message: pop3_uidl_format setting is missing from config file Which setting for pop3_uidl_format should I set to prevent the e-mail being downloaded again?

I'm hoping to migrate to dovecot from qpopper, with the eventual goal of enabling IMAP. However, my qpopper installation is fairly specialized, so I thought I'd ask here to see if anyone could get me headed down the best path. Here's the situation. I'm running FreeBSD and have a virtual domains setup with an extremely hacked LDA to do delivery to mailboxes within hashed

Hello, I'm preparing to convert from qpopper + UW-IMAP to dovecot. So far testing has gone very well. One problem we haven't figured out is that long-running POP sessions keep the mailbox locked, so that the MDA times out while trying to deliver. We're using "maildrop" as our MDA if that matters. We don't see this issue for dovecot IMAP sessions. During long-running

Heya, We are in the process of migrating from qpopper to dovecot as POP3 server (and IMAP as well) and we hit the UIDL issue with dovecot. Qpopper uses its own algorithm to create UIDL values and if you set it up to write them down in the mbox file as X-UIDL, then dovecot can use them (pop_uidl_reuse = yes). But if you don't use that feature from qpopper, than X-UIDLs are missing and there

Hello, does anybody know how to make XUIDLs compatible to qpopper? I'm migrating from qpopper and one of my test-migration-accounts leaves the mail on the server. As soon as I switch to dovecot it downloads the mails again and again.. bye! Dominik

I currently have a Centos server with Sendmail and Qpopper supporting about 50 mail users. I am planning to replace Qpopper with Dovecot to allow some users to have IMAP access to their mail (others will still use POP3.) Is there anything special to be aware of in setting up this migration? Thanks for your comments. Gerald

Hello All, I am new to Dovecot and the Dovecot mailing list. I am trying to migrate an existing Exim + qpopper - mbox (pop3 only) installation over to Exim + Dovecot using mdir (pop3 and imap) And am running into problems with preserving the XUIDL headers. I am running Dovecot 2.0.14 I have used the mb2md.pl script : http://dovecot.org/tools/mb2md.pl from this page

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

I migrated from UW IMAP/Qpopper to Dovecot using: # indexes on /var/indexes is faster: local, not NFS mouted default_mail_env = mbox:~/mail:INBOX=/var/mail/%u:INDEX=/var/indexes/%u # Qpopper pop3_reuse_xuidl = yes The new mail is sent to in /var/mail/%u in mbox format How can I migrate some users to maildir and have them receive their emails either in POP3 or IMAP. (lots of big files to

I''ve got qualcomm''s qpopper2.2, and am not sure if its vulnerable. The advisory mentions pop and imap servers, but only says: version of IMAP (Section B). If your POP server is based on the University of Washington IMAP server code, you should also upgrade to the latest version of IMAP. Until you can take one of these actions, I installed the new imapd about 3

Hi List, what do you think is the best way to migrate (to a new maschine) round about 30000 mboxes (Qpopper) with an amount of 43Gigs data, to maildir format (Dovecot). I think there are two ways: 1. - stop services (smtp and pop3) on the old maschine - copy the mboxes to the new maschine - run a conversion script (for excample: "Perfect_maildir" http://perfectmaildir.home-dn.net/)
