[Dovecot] Courier->Dovecot Migration Issue
by Tony Rutherford 18 Feb '10

18 Feb '10

For testing purposes, on a small set of users, we've run the courier-dovecot-migrate.pl script. We are converting from Courier 0.43 to Dovecot 1.2.9. For the most part, things seem to be ok. However, an iPhone IMAP client user is reporting a problem where some of her messages don't show up. Even stranger is the fact that these same messages do appear when using Outlook 2k7 for instance. The common denominator for when the messages are missing seems to be whether or not the message appeared in both the Courier IMAP and Courier POP3 uid files. The missing messages appear in the CourierIMAP file, but NOT the Courier POP file. Here is a snippet from the resulting Dovecot-uidlist file: 3 V1141844265 N12392 9338 P00cf2eb6_fadc_4992_ad3a_57cc83a16eab W5146 :00cf2eb6_fadc_4992_ad3a_57cc83a16eab:2,S 9788 P0b18a2d6_97dd_4712_a09c_23c7a3d59467 W4055 :0b18a2d6_97dd_4712_a09c_23c7a3d59467:2,S 9942 P0b3cfd0b_1fc7_47b3_805f_b369a3bb6c65 W4359 :0b3cfd0b_1fc7_47b3_805f_b369a3bb6c65:2,S 10100 Pe178f1ed_d648_47e8_807a_3e2d655d7f84 W12028 :e178f1ed_d648_47e8_807a_3e2d655d7f84:2,S 10101 Pe3f28a53_a4d4_4f3d_babe_5df72bc35b47 W13974 :e3f28a53_a4d4_4f3d_babe_5df72bc35b47:2,S 10102 Pf3c3024b_2850_43ef_a397_d5cae5c8f537 W7177 :f3c3024b_2850_43ef_a397_d5cae5c8f537:2,S 10104 P6e808a68_0a7b_4528_aa67_4cc16361c56b W10817 :6e808a68_0a7b_4528_aa67_4cc16361c56b:2,S 10105 P65c8218d_7b2a_43b7_82a4_2743025bd954 W3579 :65c8218d_7b2a_43b7_82a4_2743025bd954:2,S 10106 P963cc43e_0355_481e_99d5_5468708bc28f W6410 :963cc43e_0355_481e_99d5_5468708bc28f:2,S 10107 P1405aefc_b98b_4a35_a7dd_a69199f724d0 W4703 :1405aefc_b98b_4a35_a7dd_a69199f724d0:2,S 10108 P67908fad_ec0a_4786_b0f1_c7cfaa23d09a W127288 :67908fad_ec0a_4786_b0f1_c7cfaa23d09a:2,S 10109 :9176f3b2_1927_4657_baa8_bfe4c39e89d4:2,S 10110 :79047185_aef7_48ec_aff2_6b71bd566acd:2,S 10111 :efe275a0_a7a8_4f47_b638_45a18bc0b108:2,S The last three entries exist in the Courier IMAP file, but NOT the Courier POP file. The resulting dovecot-uidlist format is different, but to be honest, I haven't been able to find the exact specification for the format of the dovecot-uidlist file (if it exists). What is really strange to me is: If there was a problem with the migration script and resulting dovecot-uidlist file, why would these messages show up fine in some client (ex. Outlook) and not others (ex. iPhone). Regards, Tony

[Dovecot] Virtual mailboxes show up twice
by Matthijs Kooijman 18 Feb '10

18 Feb '10

Hi all, I've been struggling a bit getting Hastymail webmail to work with my virtual mailboxes. After a while, I discovered that my virtual mailboxes are listed twice: Once with \NoSelect and once without. See the following (partial) LIST reponse: * LIST (\Noselect \HasChildren) "/" "virtual" * LIST (\Noselect \HasNoChildren) "/" "virtual/foo" ... * LIST (\HasNoChildren) "/" "virtual/foo" This makes somewhat sense, since my "virtual" namespace is a subdir of my default namespace: mail_location = Maildir:~/Mail:LAYOUT=fs # Default namespace, uses mail_location above namespace private { prefix = separator = / inbox = yes } # Virtual mailboxes namespace private { prefix = virtual/ separator = / # Store virtual mailbox in a "virtual" subdirectory. We use the fs layout, # so nesting of mailboxes is done using normal filesystem nesting. location = virtual:~/Mail/virtual:LAYOUT=fs } Now, should dovecot handle this configuration transparently by hiding the virtual directory from the default namespace, or is this configuration just not supported and should the virtual directory be outside of ~/Mail? The current wiki documentation on the virtual plugin currently does suggest this configuration, its examples point to ~/Maildir/virtual. Gr. Matthijs

[Dovecot] configuring overquota message
by Leonardo Rodrigues 18 Feb '10

18 Feb '10

From dovecot 1.2.10 sources i have: src/plugins/quota/quota.c #define DEFAULT_QUOTA_EXCEEDED_MSG \ "Quota exceeded (mailbox for user is full)" struct quota_settings *quota_settings_init(void) { [ .... ] quota_set->quota_exceeded_msg = getenv("QUOTA_EXCEEDED_MESSAGE"); if (quota_set->quota_exceeded_msg == NULL) quota_set->quota_exceeded_msg = DEFAULT_QUOTA_EXCEEDED_MSG; [ .... ] but i havent found, in all the sources, where the QUOTA_EXCEEDED_MESSAGE is feeded by something from dovecot.conf or anywhere else. question is: isnt it possible to configure the quota exceeded message from dovecot.conf ?? Do i really need to rebuild dovecot changing the message on quota.c for acchieving that ? -- Atenciosamente / Sincerily, Leonardo Rodrigues Solutti Tecnologia http://www.solutti.com.br Minha armadilha de SPAM, NÃO mandem email gertrudes(a)solutti.com.br My SPAMTRAP, do not email it

[Dovecot] Problem in sharing mailboxes across users
by Rampage 18 Feb '10

18 Feb '10

Hello everyone, I'm trying to configure dovecot to allow users to share their imap folders. I've followed the wiki and i'm near to accomplish my tasks, when i set ACL properly on folders using imap commands the other user can see the folder as shared, but i can't subscribe to it or even access its content using any email client (like thunderbird) couse it looks like the path to the shared folder is not complete. i mean when i go to "manage subscriptions" i can see the shared folder from the other users as "shared/user@domain/sharedfoldername" but since only "sharedfoldername" is present i cant subscribe to it. am i missing somethimg? like do i need to setup a particular directory tree on the filesystem? thnx in advice for your help. Best regards. Francesco.

[Dovecot] Problem with allow_nets passdb parameter and Postfix
by Неворотин Вадим 18 Feb '10

18 Feb '10

I use Dovecot for SASL authentication from Postfix. In Postfix main.cf I have: smtpd_sasl_type = dovecot It works good, but now I need to allow users to connect by IMAP only from given IP adresses. I've added extra field allow_nets to passdb in Dovecot, and IMAP authentication works fine. But now I can't connect to my SMTP server because when smtpd ask dovecot about user authentification, dovecot always denied it. Even if I try to connect to SMTP from correct IP, listed in allow_nets for user. In dovecot log I have messages about incorrect ip like this: dovecot: 2010-02-15 13:28:51 Info: auth(default): passwd-file(malamut): lookup: user=malamut file=/etc/dovecot/temp.users dovecot: 2010-02-15 13:28:51 Info: auth(default): passdb(malamut): allow_nets check failed: Remote IP not known dovecot: 2010-02-15 13:28:53 Info: auth(default): client out: FAIL 7 user=malamut Problem is clear: smtpd don't send client IP to dovecot authentication socket. But I need to limit the ability of connection to users only from specific IP. Both for SMTP and IMAP. How can I do that? I use dovecot 1.0.15 and Postfix 2.5.5 on Debian Lenny.
