similar to: Problems with the pop3 part of dovecot

Hello, I recently migrated to Dovecot from Courier-IMAP and i'm very happy with the IMAP Performance and Dovecot in general. The server is running qmail-ldap and i'm still using the qmail pop3 daemon for the POP3 users. Because i want to get rid of qmail completely (switching to exim) i just tried to replace the qmail pop3 daemon with dovecot too. Immediately after the migration the

Hi, I'm working with dovecot 1.0.beta2 for pop3 only and have set index=memory, so no indizes are created on the disk. pop3_uidl_format is set to %f. The maildirs are located on an nfs-share. So generally, this setup is very similar to what qmail-popup and qmail-pop3d does. However, everytime I'm switching from qmail-pop3d to dovecot, the system load increases from less than 2 to more

hello johannes, i just discovered your wonderful plugin for dovecot. it was pretty much exactly what i was looking for, only that i didn't know that yet :) "Instead of moving mail into special folders, the user has two actions available: moving it out of the SPAM folder and moving it into the SPAM folder. The dovecot plugin watches these actions [...] and tells dspam that it made an

Hello, In the past we've had 4 loadbalanced servers configured with courier pop3 and dovecot handling respectively POP3 and IMAP connections. These 4 servers have a shared NFS storage on a Netapp FAS3220 controller with SAS disks. This setup is handling 50 POP3 sessions per second without any problems. Now we're installing 6 new loadbalanced servers to do the same job on the same

Hi all I'm considering moving over my POP3 service from qmail-pop3d to Dovecot for the following reasons: - Support for Maildir++ which I have yet to implement - Already using Dovecot for IMAP, so makes sense i.t.o Maildir++ - Support for SQL based user authentication My primary concerns are performance and security. Before I go down that route of migrating away from qmail-pop3d, I'd

Hi all, Please correct me if I'm going about this the wrong way. We currently have a 3 system Mail server set up - two machines are the load balanced frontends running Dovecot and Postfix, and the third machine is our NFS. Over the past 4 months or so, I've tweaked and optimized our mail servers, and we receive roughly 3 million emails a day combined through this setup. Sometimes,

If so, I could auto-archive them. Yes, they are marked read. See "Flag changes" on

Hi When activating antispam plugin in imap protocol, when sending an email, Evolution/Thunderbirdkeeps infinitely "Sending authentication information", and Dovecor logs shows "dovecot: May 28 10:14:35 Error: child 6910 (imap) killed with signal 11"; lots of empty folders in /tmp are created with names like "antispam-mail-ZvyWeZ". I am using Dovecot1.1 rc15 compiled

Hi, Currently we support Courier POP and IMAP for all our users (users can use IMAP as well as POP at the same time). We are thinking about moving to Dovecot; but first moving away from Courier IMAP to Dovecot IMAP (and maybe later also move to Dovecot POP). This would create a mixed environment; after some research I have the following questions. To not break POP3 Courier and still be

Hi, guys. I've read the information in the Wiki about making dovecot's UID's match Courier's UID's in the POP3 server, so that a UIDL command on either server will return the same UID's for the same group of messages. However, what I've read doesn't match what I'm seeing in Courier. Courier appears to keep the UID numbers for messages that it uses for the POP3

Hi Timo/all Help me please, i am in the process of migrating courier to dovecot 1.1.14. I want to do migration as users loging so i am using this script * http://www.dovecot.org/tools/courier-dovecot-migrate.pl *, When i do use post-logging script to migrate* POP3*, its downloading messages again (*Duplicating messages)* , as some of our users prefer to leave messages on server. If i run the

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

Hi list, Here it is: I have compiled with no problem courier-imap-4.0.4 on this arch (x86_64). Now I want to update my install with 4.0.6. I want to do this because the server is not yet in a production state, so if a major flaw affects courier-imap in the future, I could react more quickly. And indeed I'm encountering problems with the make process (Since I initialy build courier-imap

Hello, In mail client users have settings leave message on server. I dont want user download those messages again. i tried with courier-dovecot-migrate.plscript after running this if i am doing send recive all messages downloaded again please help me in this. Thanks Shailesh Singh

Having FC3 systems and utilizing Dovecot, I have come to rely on some of the information I get from the daily logwatch run. Logwatch, by default, doesn't properly recognize dovecot's information in the messages file, but it is easy to tweak. The patch below will give you some statistics regarding POP3 and IMAP usage. I believe I grabbed all of the differences in the unified diff

Hi everyone Been spending the whole day on the wiki and in the list archives on using dovecot for POP3 mail. I'd like to present my findings and ask for some feedback. Our current software setup: * Courier-IMAP running POP3/IMAP * Postfix MTA * MySQL backend for user and login info As for the system layout, it looks like this: * NFS server which is the same server that houses single

Manao ahoana, Hello, Bonjour, We currently run courier POP . We would like to switch to Dovecot. I encounter problems when migrating the UIDL because we have big Maildirs and POP re-downlading the data is not possible for most of the users. I tried the http://www.dovecot.org/tools/courier-dovecot-migrate.pl script but I still have the re-downloading event. What are your stories and advices

Hi, I found a problem in the courier conversion script (courier-dovecot-migrate.pl). In some cases, it does not correctly preserve the order of POP3 UIDLs. Consider the following case, when courierpop3dsizelist contains: /2 9000 1327481629 AAA1:2,S 10000 21:1327481629 AAA2:2,S 10000 22:1327481629 AAA3:2,S 10000 23:1327481629 AAA4:2,S 10000 24:1327481629 AAA5:2,S 10000 25:1327481629 BBB11:2,S

Hi All, I have compared Dovecot performance to Courier and it appears that as a POP3 server Dovecot is slower in 2 times but as an IMAP server it is faster in 1.5 times. The same node (16CPUs), testing time is 30 min, please see results and dovecot configs attached. Benchmark software is MStone used by Sendmail Inc so is is quite reliable. I do not see anything else to tweak in Dovecot to
