[Dovecot] "Dumb" proxying?
by Dan Bongert 04 Apr '08

04 Apr '08

I'm a database noob, and it really seems like it would be overkill for my setup: I just want to proxy all connections from my DMZ to my internal mail server -- same internal server for all users. I used to use perdition for this set up, but am having issues getting it to play nicely with my new servers. Can I bypass all of the SQL stuff and just have dovecot forward all POP/IMAP connections to a specific server? Or perhaps set up a wild card lookup in the database (preferably something serverless like sqlite) so that no matter the query, it'll return one server? I don't really want to add "database management" to my list of jobs I have to do, especially for ~1000 users, and when I don't handle user creation/deletion. -- Dan Bongert dbongert(a)ssc.wisc.edu

[Dovecot] outlook2007 shows frequent imap disconnect no matter what outlook-idle setting in dovecot.conf
by Kielbasiewicz, Peter 04 Apr '08

04 Apr '08

Hello, I saw the problem quite often in various posts but could not find a real solution . Problem is that I frequently get annoying popups from outlook 2007 about imap idle timeouts which block working with outlook until the popup is acknowledged. The popup says: Your IMAP server closed the connection. This can occur if you leave the connection idle for too long. Protocol: IMAP Server: testhost Port: 143 Error Code: 0x800CCCDD I tried to run dovecot with or without "imap_client_workarounds = outlook-idle" but do not see any difference. I am running dovecot on Red Hat Enterprise Linux Client release 5.1 (Tikanga). Below is the output of some commands to get a clue about my config. Background info: Our primary mailboxes are on exchange servers. As there is a size limit on the server mailboxes I am evaluating a local storage solution for our users. Thus I set up an additional mailbox in outlook using IMAP. Local .pst files can not be backuped easily (especially when outlook is running) and I am investigating a local IMAP server where users can move their mails to. This server can easily be backuped (even incrementally when using Maildir) and users do always have access to their mails. The drawbacks are that users must have an extra login to the imap server because I have no ldap access to the company AD server from our local site domain. The solution will not be accepted though if I can not prevent the frequent disconnect popups.

[Dovecot] Confusion of Sieve filter scripts and the file separator. (Amatuer Siever)
by Jack 04 Apr '08

04 Apr '08

Hello, I have just been playing around with sieve filters to split up all my incoming mail into the correct directories. I have created some subdirectories to put mailing list emails in and just want to check if my thinking is correct. I am using namespaces with the '/' character as the separator. When creating the fileinto line on my sieve scripts I thought I would have to use the '/' character to separate the folders (as horde mail also does), but that doesn't work (and produces a "Invalid folder" error) instead I must use the '.' character. I am using the dovecot deliver module and managesieve for my sieve stuff (dovecot 1.0.13). I am just wondering if this is the correct behaviour or if it is a bug of sorts. Cheers. From, Jack

Hi, I've installed dovecot 1.0.13 on FreeBSD 6.3 RELEASE and now trying to configure it.

The problem is: when a user logs in as 'abc' (without domain part) dovecots creates a directory /var/MailRoot/domains/abc and check mail there (as I understand because %d is blank). My question is how to config dovecot so it automatically add default domain %d is blank. Thank you for help. Dien Phan

[Dovecot] Icedove (Thunderbird) crashes when reading IMAP messages
by Cam Ellison 04 Apr '08

04 Apr '08

This is a Debian lenny/sid installation. Dovecot has been installed on it for over a year, with no problems. Lately (i.e. the past few months), if I attempt to read a message, Icedove crashes. It does not do this when I read a message downloaded from the ISP's POP3 server (not that I do this very often - almost all my mail goes through Dovecot). I am now having to read email with KMail, but cannot send from it - that's another story. Googling for the past month or so reveals nothing: there seems to be no bug filed for this, and indeed I think it is an odd communication problem with dovecot that has not been seen before. Has anyone any experience with this, or any ideas how I should go about resolving it? I have not done so (because I don't know how to use the data, not being a coder), but can run strace and/or valgrind on icedove if that will help.

[Dovecot] Lmtp between hosts? (postfix/dovecot/ldap)
by k bah 02 Apr '08

02 Apr '08

I have 2 hosts: (a) - dovecot-1.0.5-6 - postfix-2.4.5-20 -> It's not the mx record for the domain, just holds the mailboxes -> Postfix uses LDAP for user lookup, dovecot too. -> Works ok if I set it to be the final mail destination, with Cyrus and Dovecot LDA (mailbox_transport). -> Has no domain associated (dns) with this ip address (b) - postfix-2.3.2-28 -> Has the mx record for that domain, has ip address that the domain points to. (users @ domain.org) -> Works ok if I install dovecot and set the mailbox_transport to be on this machine, both with dovecot and cyrus. What I'm trying to do: Have host (b) to receive mails for that domain, and by setting it's transport_maps to be /etc/postfix/transport, and there (tranport maps) point to host (a), using ltmp: "domain.org lmtp:ip_address_machine_A:24" ("domain.org lmtp:inet:ip_address_machine_A:24" does not work, gives me "fatal: valid hostname or network address required in server description: inet:ip_address_machine_A:24") Both machines have /etc/services with lmtp to port 24 tcp/udp. http://www.postfix.org/transport.5.html was not so clear to me. Ok, when I took out the "inet" part on the transport maps file, it connected to the host (a), which has this on master.cf: "machine_A_ip_address:24 inet n - n - - lmtp" it "worked", since machine (b) (received the mail and has mx record) delivered the mail to machine (a) (holds mailboxes, runs dovecot), but that stopped, machine (b) connects to port 24 on machine (a), and stays there, connected, without saying nothing (sniffed it). When I kill the connection (kill postfix on machine (a)), machine (b) complains on the log file: postfix/lmtp[704]: msg_id: to=<xx(a)xx.yy>, relay=machine_A[machine_A]:24, delay=223, delays=0.08/0.01/223/0, dsn=4.4.2, status=deferred (lost connection with machine_A[machine_A] while receiving the initial server greeting). -- questions -- I don't know if I'm doing things wrong (configuration error) or the wrong thing (should try other ways), so my questions: 1) Is this setup going to work ever, or it's wrong to try to get it to work? I want to hold mailboxes on a different host, and now I got to use dovecot (in case I hear: "try it with cyrus instead" =o)). 2) Viewing from the machine that receives the mail, and has mx record, the transport should be lmtp, right? Since it's now a matter of "delivery". Postfix: <...> -> <qmgr> -> (<local> or <smtp> or <pipe>) When using lmtp, I'm in <local>?? I mean, to get the message to the other machine (just mailboxes, no mx) I SHOULD USE LMTP(?) 3) Viewing from the machine holding the mailboxes, is there a way to make dovecot listen on that port? Or should I continue to use Postfix, and use postfix on this machine to deliver to dovecot (dovecot lda config works ok if using 1 and only 1 machine for everything - mx record, mailboxes). With Cyrus I talked lmtp directly, Postfix receives the mail and uses lmtp to talk to cyrus, using a unix socket. If anyone replies to the topic, and the discussion goes deeper on some of the alternatives, I paste my configs and come with further details, since what's working isolated I didn't paste here. Previous tests with just Cyrus or Dovecot on 1 machine setup worked, so I think it would just "bloat" the mail with information. thanks = -- Powered by Outblaze
