[Dovecot] mbox/maildir mixed setup with system/virtual mixed users
by Victor TARHON-ONU 09 May '11

09 May '11

Hello Everyone, I'm using dovecot 1.0.7 (not sure how relevant it is though) configured to handle both sytem users and virtual users. The system users are handled by default (PAM), while the virtual users are handled pretty much like this: passdb passwd-file { args = /var/spool/vmail/%d/auth/%n } ...And mailbox and folder location settings: userdb static { args = uid=mail gid=mail home=/var/spool/vmail/%d/mail/%n mail=mbox:/var/spool/vmail/%d/imap/%n:INBOX=mbox:/var/spool/vmail/%d/mail/%n } Everything works perfectly with the inbox and mail foder in mbox format. Now, what I'm trying to accomplish is to reconfigure dovecot to create and handle the secondary mail folders (/home/user/mail for system users and /var/spool/vmail/domainname/imap/user/imap for virtual users) in maildir format. I tried to define some name spaces to make this happen, but whatever I to do make one work (either the virtual users or the system users) would make the other non-functional. By example, I have these name space definitions and the virtual users work fine with maildir: namespace private { separator = / prefix = "#mbox/" location = mbox:/var/spool/vmail/%d/imap/%n:INBOX=/var/spool/vmail/%d/mail/%n inbox = yes hidden = yes } namespace private { separator = / prefix = location = maildir:/var/spool/vmail/%d/imap/%n hidden = yes } Maybe I didn't fully understand the namespace concept, but I was unable to make them apply only to one location of the imap folders locations or another. Can anyone give me a hand with this, if this setup is even possible? --

[Dovecot] Spelling error in #define ?
by Peter Mogensen 09 May '11

Hi, I stumbled over this define in lazy-expunge-plugin.h: #ifndef LAZY_EXPUNGE_PLUGIN_H #define TLAZY_EXPUNGE_PLUGIN_H Isn't there a "T" too much? http://hg.dovecot.org/dovecot-2.0/file/036260ae0261/src/plugins/lazy-expung… /Peter

[Dovecot] Restricting IMAP
by Matt 09 May '11

09 May '11

I want to restrict IMAP use too 127.0.0.1 and to only certain usernames. Such as fred(a)my777domain.com would be allowed to use IMAP. How would I do that with Dovecot or can I? Basically I want webmail to work with IMAP regardless of username but I only want certain usernames allowed to use IMAP remotely.

[Dovecot] example-config mail_log plugin options

Hello, dovecot-2.0.12/doc/example-config/conf.d/10-logging.conf contains # mail_log plugin provides more event logging for mail processes. plugin { # Events to log. Also available: flag_change append #mail_log_events = delete undelete expunge copy mailbox_delete mailbox_rename # Group events within a transaction to one line. #mail_log_group_events = no # Available fields: uid, box, msgid, from, subject, size, vsize, flags # size and vsize are available only for expunge and copy events. #mail_log_fields = uid box msgid size } "mail_log_group_events" seems to be gone (when and why?). And it's now "save" instead of "append", with "mailbox_create" also available.

[Dovecot] NONEXISTENT handling
by Michael M Slusarz 09 May '11

As of 2.0.12, looks like NONEXISTENT response code isn't working properly again. Previously brought up issues relating to this here: http://markmail.org/message/jxbgdfv26pws66og With a nonexistent mailbox "FOO", I see this: 1 DELETE "FOO" 1 NO Mailbox doesn't exist: FOO // Should be: 1 NO [NONEXISTENT] Mailbox doesn't exist: FOO 2 RENAME "FOO" "BAR" 2 NO Mailbox doesn't exist: FOO // Should be: 2 NO [NONEXISTENT] Mailbox doesn't exist: FOO michael

One update however with #md implementation is that I just tried one more thing in my alpine configuration and [/] has vanished after that so probably I don't have to configure for password-less alpine on the email server. Here is the specific configuration from my /etc/pine.conf or .pinerc 1. maildir-location=../../Mail/${LOGNAME} #folder-collections=Mail {localhost/novalidate-cert/ssl/user=${LOGNAME}}[] <---- Commented. 2. folder-collections=Mail #md/../../Mail/${LOGNAME}/.[] With this configuration, all folders appear fine. Folders : INBOX sent-mail saved-messages ABC PINE_FOLDER Queue Sent Trash sent-mail-apr-2011 In addition, I am going to change sent messages and saved messages setting as below so that when users are migrated from ~/mail to /Mail/user/ (maildir) format then their newly sent emails and saved messages also continue to go into /Mail/user/.sent-mail and /Mail/user/.saved-messages folder respectively. default-fcc=sent-mail default-saved-msg-folder=saved-messages Thank you everyone for their inputs. Appreciate it. UG
