[Dovecot] Dovecot upgrades break Blackberry instant email (BIS)
by interfaSys sàrl 17 Sep '10

17 Sep '10

Hello, Just like when upgrading to 1.2, upgrading to 2.0.1 confuses RIM's BIS servers and users don't have instant email anymore on their Blackberrys. Under normal conditions, the BIS servers keep one open connection per email account with Dovecot. They're using IMAP IDLE to monitor changes and push them to devices very quickly. After an upgrade, all changes. The BIS servers can't maintain an idling connection anymore, they just poll the Dovecot server when they feel like it (every 2-15 minutes). There is one way to fix this on the devices: The users have to re-create the email account. I don't find this very convenient and was wondering if there was something that could be done on the Dovecot side? Last time it happened, I tried clearing the indexes and resetting file permissions, but nothing helped. Cheers, Olivier

[Dovecot] SSL stops working after server upgrade
by "Ing. Daniel Rozsnyó" 17 Sep '10

17 Sep '10

Hello, after an upgrade of the dovecot server, I can not use SSL connections. Can you help me solving the issue? When googling for the error, there is an opinion that the client is broken (in my case Thunderbird, 3.1.3), but I rather see the issue in the server, because I was upgrading my gentoo box by hand, and the secure imap stopped to work after that. Is there a more verbose SSL logging than the default verbose ssl = yes? It's output is attached below. Also, maybe only a configuration detail is missing, since with this version of dovecot, the configuration files were broken into several smaller files, but for my first look they contained the options I had used before. Thanks.

[Dovecot] [DC2.x ]pop3-login seg faults when compiled with gcc 4.5.2 and gold
by interfaSys sàrl 16 Sep '10

16 Sep '10

Hello, On FreeBSD, Dovecot 2.0.1 compiles fine with gcc45 and the other services have no problem, but even without any optimizations (CFLAGS) at all, pop3-login seg faults when a user tries to connect to Dovecot using POP3. As this is not the only application that has a problem with the latest version of gcc (mod_php), there may be nothing that can be done on the Dovecot side, but I thought I would mention it, in case it was due to some bug in the pop3-login code. Cheers, Olivier

[Dovecot] imap processing spinning on the CPU
by Daniel J. Luke 16 Sep '10

16 Sep '10

Version: 2.0.2 OS: Mac OS X 10.5.8 IMAP Client: Apple Mail.app on 10.5.8 Since upgrading to 2.0.2 I've noticed one user ends up with 4-5 imap processes all using as much CPU as they can get. I know of one other person who is seeing this on a FreeBSD server (that person moved back to dovecot 1.2 which 'solved' the problem there). I didn't notice anything in the list archive about this, but maybe I missed it.

[Dovecot] dovecot as exchange server?
by Jacek Osiecki 16 Sep '10

16 Sep '10

Hi, This might be a stupid question, since my knowledge about Exchange is really poor... Since I've got iPhone, I have noticed that IMAP mailbox support is quite crippled in this device - in comparison to Exchange mailboxes... As I assume that it would be easier to convince Bill Gates to install linux than to convince Steve Jobs to change anything in his "perfect phone", I started searching for something that could serve emails similarly to Exchange. Since gmail provides Exchange access, and they definitely don't run a single huge MS Exchange server, I assume that it is somehow possible to implement Exchange protocols - or am I wrong? So, finally - if it is possible to use Exchange protocol, would there be any plans for implementing it in dovecot? Best regards, -- Jacek Osiecki joshua(a)ceti.pl GG:3828944

[Dovecot] dsync mirror duplicates problem
by Waldemar W. 16 Sep '10

16 Sep '10

Im trying to sync 2 mailserver with dsync mirror functionality. Problem occurs when mails arrive in the same folder on both sides then dsync sometimes runs into problems and duplicates that entrys on both side(2mails then with same content). After running again the same happens again(now 4 mails with same content on every side). And then duplicates this mails on both sides on every run :( Anyone with same problem or is something that could cause this? I tried dsync with and without -f option but no change. Im running dovecot 2.0.1 together with dovecot sieve (latest hg version). thanks, Waldemar

[Dovecot] Dovecot2 and mdbox problem
by Michael Grosseck 16 Sep '10

16 Sep '10

Hello, I've just installed Dovecot from the http://xi.rename-it.nl/debian/ repository. But I have a problem with the mdbox Format. When the home folder is empty Dovecot should create the folder structure if the first mail arrived or the user logs in the first time. But I get following error: Sep 16 12:30:41 smtp dovecot: lmtp(31244): Connect from local Sep 16 12:30:41 smtp dovecot: lmtp(31244, info(a)example.de) Error: file_dotlock_open() failed with file /var/mail/es030107p1/mdbox/mailboxes/INBOX/dbox-Mails/dovecot.index.log: No such file or directory Sep 16 12:30:41 smtp dovecot: lmtp(31244, info(a)example.de) Error: Opening INBOX failed: Mailbox doesn't exist: INBOX Sep 16 12:30:41 smtp dovecot: lmtp(31244, info(a)example.de) 0ZQgDbkNkkwMegAA00WXAw: msgid=<20100916123041.4781A4F4138(a)smtp.example.de>: save failed to INBOX: Mailbox doesn't exist: INBOX Sep 16 12:30:41 smtp dovecot: lmtp(31244, info(a)example.de) Error: BUG: Saving failed to unknown storage Sep 16 12:30:41 smtp dovecot: lmtp(31244): Disconnect from local: Client quit Also if I try to create a mailbox by hand I get a similar error. doveadm(info(a)example.de): Error: file_dotlock_open() failed with file /var/mail/es030107p1/mdbox/mailboxes/INBOX/dbox-Mails/dovecot.index.log: No such file or directory doveadm(info(a)example.de): Error: Can't create mailbox INBOX: Internal error occurred.
