[Dovecot] Dovecot as LDA with Postfix

I have been attempting to replace Procmail with Dovecot as the LDA for my Postfix mail server, but without success. Below is a truncated output from the /var/log/maillog.

I keep getting this temporary failure message. As soon as I revert to Procmail everything works fine. I am simply trying to deliver to mbox format on a FreeBSD 6.1 STABLE system. Nothing exotic. I am using SASL2. Authentication is via saslauthd -a sasldb. Perhaps I do not have that configured correctly in Dovecot. Dovecot does work fine as a POP server though, so it is running at least partially correctly. I would appreciate any assistance. -- Gerard Seibert gerard(a)seibercom.net Democracy is a device that insures we shall be governed no better than we deserve. George Bernard Shaw

[Dovecot] RC7: its issues or mine?
by David Lee 31 Aug '06

31 Aug '06

Background: I'm new to dovecot (although with many years Washington IMAP behind me). We're considering migrating from Washington IMAP to dovecot on the main service here, and have just started trying dovecot, using RC7. Washington, IMAP has the usual(-ish) "/var/spool/mail" shared area for the INBOX (trad. UNIX "From " format); a user's folders default to being in their home directory (same format). We are looking towards a "minimal effort" migration to dovecot, so wish to keep this layout. (In an ideal world, we would re-think, including "maildir" etc. But that's not an option at the moment.) I have encountered three issues (so far); I'm not sure whether their mine or something in dovecot (if the latter, whether bugs or features; whether RC7-specific issues; etc.). 1. The overall description of "default_mail_env" seems inadequate (in the conf file, "doc/variables.txt" and "doc/mail-storages.txt"). I'm trying: default_mail_env = mbox:~:INBOX=/var/spool/mail/%-2.02i/%u:INDEX=/tmp/indexes/%d/%n and that seems OK-ish. (The extra "%-2.02i" is because we subdivide the otherwise huge "/var/spool/mail/" directory using the user's uid-mod-100.) But the mere act of an IMAP "login" commands creates a directory (empty) with the liternal name of ~ (tilde). (An IMAP 'list "Mail" "*"' command successfully finds the usr folders in the 'Mail' subdirectory of the user's home directory.) It's almost as if the 'default_mail_env' is telling it to create (literal) '~' before realising that this is shorthand (as in C-shell) for home directory. 2. We have some Pine usage in our UNIX cluster. Historically this has taken advantage of the Pine "rsh mailmachine /etc/rimapd" ability to avoid the need for the password: pre-authentication etc. (Yes, we realise that 'rsh' has security issues.) But when I try making symlink "/etc/rimapd" point to "/usr/dovecot/sbin/dovecot" this fails: Error: Can't use SSL key file /etc/ssl/private/dovecot.pem: Permission denied We have: /etc/ssl/certs/dovecot.pem (mode 444) /etc/ssl/private/dovecot.pem (mode 400) for the sake of secure-IMAP (port 993). But why does this come into the equation at all for this (none-SSL) "rsh ... /etc/rimapd" usage? 3. I was developing and testing this here at work using an account that I mostly use from home using Outlook Express. I was very careful (I think!) only to use the read-only "examine INBOX" command (not "select INBOX"). When I went home and tried it as usual (connecting to our production Washington IMAP service reading that INBOX). But OE showed all the email (including previously read) as "unread" (closed envelope icon). It seems that dovecot has done something to the message headers (even under "examine") that has worried OE. Any thoughts? Finally any hints for NFS-based working? We have a farm of a few Fedora machines running the IMAP processes and the sendmail locally-delivery. Our current "/etc/fstab" NFS spec. for the INBOX area (on a NetApp) is: rw,noac,actimeo=0,vers=3,tcp,timeo=600,rsize=32768,wsize=32768,hard,intr,fg,nosuid Any changes? Issues? Thinks to consider? Etc. Many thanks. -- : David Lee I.T.

[Dovecot] IMAPS + Outlook
by Mark Adams 31 Aug '06

31 Aug '06

Hi, We have been using Dovecot 1.0 to serve Maildir format over IMAPs to a client with an office of around 30 people, and a remote office of 10, all using Outlook 2003. While users in the base office (location of server) are not having issues with the server users in the remote office are often having problems with Outlook freezing, or not being able to connect. The dovecot log shows them logging in, but users report not being able to open any mail. We are having similar problems with 2 users that are often on 3G cards, in that the headers download but when they try to open the file it gives the 'must be online to download the message' error, even though they are still connected to their 3G. The net connection for the server is 2mb sdsl, which I have tested myself (using thunderbird on linux!) and achieved good throughput and reliable mailbox navigation. Is there any Outlook work arounds we could be using? (currently using idle timeout work around) Any help is very much appreciated. Thanks, Mark

[Dovecot] dovecot with Calendar or Contacts?
by ajmcello 31 Aug '06

31 Aug '06

I have the SyncKolab plugin installed with Thunderbird. I can't get it to work properly. Maybe I have to have a Kolab Server? I can get my Address Book contacts to sync with an IMAP folder when I check Sync IMAP, but I can't get it to work the other way around. From their website, it seems possible: [begin paste] SyncKolab SyncKolab was written to add kolab functionality to thunderbird. It reads a selected Imap folder and synchronizes it with the local address book and calendar. It has been tested under Thunderbird 1 for Windows and Linux. What is Kolab? What it does is, that it loads all your contacts (from a selected address book) as well as events and todos (from the selected calendar), and synchronizes them with a selected imap folder. Where every contact is stored as an vcard and every event,todo as iCalendar. For more information http://kolab.org/ The idea behind this is, that you can now have your contacts+calendar entries stored on the imap server. so you can actually have the same addresses on more than one computer. The kolab project has a groupware server that uses imap to exchange calendar entries and vcards. But you can also setup simple sharing in your office if you have f.e. cyrus by symlinking shared folders. [end paste] Yeah, I've explored the Outlook connectors some. Do any exist that are free/open source?

[Dovecot] dovecot with Calendar or Contacts?
by ajmcello 31 Aug '06

I don't know. Is IMAP capable of serving "Special" folders? If so, then I would say yes. Are there plans for dovecot to support this feature? And if not, does anybody know of a way to sync up Contacts & Calendar information from one client to another (using the same id) with Thunderbird, Outlook, or another MTA? Curious to know. Thanks.

When I attempted to import my Contacts list into dovecot, my mail client told me that the IMAP server did not support "Special" folders. Is there a way to to do the contacts, or sync up Contacts & Calendar from a database or something else? I'm using both Thunderbird and Outlook. Thanks.

[Dovecot] [long message] problem with imap authentication process
by computational_complex-forthespam＠yahoo.it 30 Aug '06

30 Aug '06

Hi guys, this is my first message in list. i've installed dovecot 1 RC 7 from sources and set it up with postfix as a pop3 mail server: all worked perfectly. Now i would like to set up a local web mail interface; most web mails (eg horde,squirrelMail) use imap to get mail; so i've to set up dovecot imap server. I've set up imap settings in config file and added imap to protocols (i don't use ssl encription): > protocols = pop3 imap But when i run dovecot, i get "USER environment missing", what does it mean? : > root@mailer:~# for i in /var/log/mail.*; do echo > $i ; done > root@mailer:~# echo $USER > root > root@mailer:~# > root@mailer:~# /usr/sbin/dovecot > root@mailer:~# cat /var/log/mail.info > Aug 30 15:58:42 mailer dovecot: Dovecot v1.0.rc7 starting up > Aug 30 15:58:43 mailer dovecot: imap-login: USER environment missing > Aug 30 15:58:43 mailer dovecot: Login process died too early - shutting down > Aug 30 15:58:43 mailer dovecot: child 3929 (login) returned error 89 As you seen, $USER environment variable was set; authentication process user id (in config file) was set to root. Mail users are virtual users and their account informations are stored to a passwd-like file. I searched in the source code the error string and found this dovecot-1.0.rc7/src/imap/main.c: > user = getenv("USER"); > if (user == NULL) { > if (IS_STANDALONE()) > user = getlogin(); > if (user == NULL) > i_fatal("USER environment missing"); > } This is the only occurrence of the error. This code is simple, Why getenv("USER") returns NULL ? variable was set when i run dovecot.... mmm..Any suggestion? Is this a bug of a process cloning /forking system in dovecot? I looked in mailinglist archives for a solution but nothing found. Anyway can you suggest me any web mail with simple configuration with postfix+dovecot virtual accounts? What about oMail-webmail? is there a way to integrate it in dovecot authentication ? Any help appreciated! Valerio

[Dovecot] filtering problem using sieve
by ajmcello ajmcello 30 Aug '06

30 Aug '06

For some reason, I cannot filter messages that have uppercase or possibly mixed casing in them. I have tried several tests by connecting to port 25 and sending messages. The ones that fail are from MAILER-DAEMON(a)mydomain.net. Here are the rules I have tried: require ["fileinto", "reject", "vacation"]; if header :contains ["To", "Cc", "Bcc", "Reply-To", "In-Reply-To"] " mailer-daemon(a)mydomain.net" { fileinto "mailer-daemon"; stop; } if header :contains ["To", "Cc", "Bcc", "Reply-To", "In-Reply-To"] " MAILER-DAEMON(a)mydomain.net" { fileinto "mailer-daemon"; stop; } if header :contains ["To", "Cc", "Bcc", "Reply-To", "In-Reply-To"] " MAILER-DAEMON(a)mail.mydomain.net" { fileinto "mailer-daemon"; stop; } if header :contains ["To", "Cc", "Bcc", "Reply-To", "In-Reply-To"] " mailer-daemon(a)mail.mydomain.net" { fileinto "mailer-daemon"; stop; } They all fail to deliver to my mail folder "mailer-daemon" and go to my inbox instead. Anybody have any ideas what I am doing wrong? Also, how can I add a wildcard so that I do not have to specify subdomains? Thank you!

[Dovecot] Dovecot public folders ACL
by typus vulgaris 29 Aug '06

29 Aug '06

Hi, all! I'm new to dovecot but trying to setup read-only public folders for different user groups. My goal is to create several public folder such as sales, operation etc with per user index. But I have some problem which I can't resolve with Google and Dovecot.Org. Now users can see and subscribe to test folder "share", but I can't block ability to delete messages via ACL. Here is file system permissions: public/.share ]> ls -la total 12 drwxrwx--- 5 share mail 512 17 авг 12:17 . drwxrwx--- 6 root mail 512 17 авг 11:04 .. drwxrwx--- 2 share mail 512 17 авг 11:18 cur -rwxrwx--- 1 root mail 21 17 авг 10:36 dovecot-acl -rwxrwx--- 1 root mail 0 16 авг 17:56 dovecot-shared drwxrwx--- 2 share mail 512 17 авг 11:17 new drwxrwx--- 2 share mail 512 17 авг 11:17 tmp my dovecot-acl file: public/.share ]> cat dovecot-acl owner lr user=typ lr But user typ can delete messages. But ACL seems working because if I remove letter 'l' from typ's setting he cannot see the folder. Here is my config: ----------8<------------ protocols = imap ssl_disable = yes disable_plaintext_auth = no shutdown_clients = yes log_path = /var/log/dovecot/sys.log info_log_path = /var/log/dovecot/info.log login_process_size = 64 verbose_proctitle = yes first_valid_gid = 0 mail_extra_groups = mail default_mail_env = mbox:/var/mail/%u:INDEX=/home/user/%u:INBOX=/var/mail/%u namespace private { separator = / prefix = location = maildir:/home/user/%u/.maildir inbox = yes } namespace public { separator = / prefix = Public/ location = maildir:/home/user/public:CONTROL=/home/user/%u/public/control:INDEX=/home/user/%u/public/index hidden = no inbox = no } mbox_read_locks = fcntl mbox_write_locks = dotlock fcntl mbox_lock_timeout = 300 mbox_very_dirty_syncs = yes umask = 0007 protocol imap { listen = 192.168.101.1:143 mail_plugins = acl imap_client_workarounds = delay-newmail outlook-idle } protocol pop3 { pop3_uidl_format = %08Xu%08Xv pop3_client_workarounds = outlook-no-nuls oe-ns-eoh } auth default { mechanisms = plain passdb pam { } userdb passwd { } user = root } plugin { } -----------------8<-------------- -- typus vulgaris
