[Dovecot] Hot to get rid of \"DON\'T DELETE THIS MESSAGE\" messages?
by foxx＠freemail.gr 09 May '07

09 May '07

I'm using Dovecot 1.0.0 (mbox) with Postfix 2.4 on my FreeBSD box, as a pop3-only server (imap is disabled). All account mailboxes are accessed using Outlook clients. I've noticed that, whenever I'm retrieving mail with pop3, a "DON'T DELETE THIS MESSAGE" is created in mbox. Although these messages are never sent to client MUAs, I found them very annoying. BTW I don't use (or used before) UW or Pine or any other c-client, therefore I assume it's a Dovecot issue. Previously I was using Cyrus and never had such a problem. Any idea how this can be fixed?

[Dovecot] sporadic slow/non response, problems copying to sent folder
by Danno Coppock 09 May '07

09 May '07

After experiencing these symptoms through many of the release candidates, we've been at v1.0.0 now for a few weeks, and they're still there. Perhaps a config issue with my setup (mbox locks?). It's really too disrupting to continue using this way. I've included symptoms, client info, mta info, log entries and config file. What other information can I provide? Please advise. Thanks, Danno symptoms: 1. Coming back to the idle client, and clicking on a newly arrived message, often a long delay (seems like minutes, sometimes) will occur before the message loads from the server. 2. Sending messages, as often as not, the client will stall, sometimes indefinitely, on "copying message to sent folder". client: * usually not more than 2-3 clients running at any time. * Thunderbird 1.5.0.10 (on XP) * Thunderbird 1.5.0.5 (on FreeBSD 5.5) mta: * Sendmail 8.13.6/8.13.6 * $sudo sendmail -bt -d0.10 < /dev/null | grep HASFLOCK OS Defines: BSD4_4_SOCKADDR HASFCHOWN HASFCHMOD HASFLOCK === log entries May 3 21:27:09 tejas dovecot: imap-login: Login: user=<annie>, method=PLAIN, rip=71.216.71.193, lip =68.224.168.249, TLS May 3 21:28:00 tejas dovecot: IMAP(annie): Disconnected May 3 21:28:01 tejas dovecot: imap-login: Login: user=<annie>, method=PLAIN, rip=71.216.71.193, lip =68.224.168.249, TLS May 3 21:32:08 tejas dovecot: IMAP(annie): Disconnected for inactivity May 3 21:37:01 tejas dovecot: IMAP(annie): Disconnected May 3 21:37:02 tejas dovecot: imap-login: Login: user=<annie>, method=PLAIN, rip=71.216.71.193, lip =68.224.168.249, TLS May 3 21:37:55 tejas dovecot: IMAP(annie): Disconnected in IDLE May 3 21:38:18 tejas dovecot: IMAP(annie): Disconnected in IDLE May 3 21:56:02 tejas dovecot: imap-login: Login: user=<danno>, method=PLAIN, rip=71.216.71.193, lip =68.224.168.249, TLS May 3 21:56:17 tejas dovecot: IMAP(annie): Disconnected for inactivity May 3 21:58:32 tejas dovecot: IMAP(danno): Disconnected May 3 22:02:31 tejas dovecot: imap-login: Login: user=<danno>, method=PLAIN, rip=71.216.71.193, lip =68.224.168.249, TLS May 3 22:03:14 tejas dovecot: imap-login: Login: user=<danno>, method=PLAIN, rip=71.216.71.193, lip =68.224.168.249, TLS May 3 22:14:10 tejas dovecot: IMAP(annie): Disconnected May 3 22:14:38 tejas dovecot: IMAP(danno): Disconnected in IDLE May 3 22:16:24 tejas dovecot: imap-login: Login: user=<danno>, method=PLAIN, rip=71.216.71.193, lip =68.224.168.249, TLS May 3 22:16:33 tejas dovecot: imap-login: Login: user=<annie>, method=PLAIN, rip=71.216.71.193, lip =68.224.168.249, TLS May 3 22:16:44 tejas dovecot: imap-login: Login: user=<annie>, method=PLAIN, rip=71.216.71.193, lip =68.224.168.249, TLS May 3 22:18:36 tejas dovecot: imap-login: Login: user=<annie>, method=PLAIN, rip=71.216.71.193, lip =68.224.168.249, TLS May 3 22:19:16 tejas dovecot: IMAP(danno): Disconnected May 3 22:19:17 tejas dovecot: imap-login: Login: user=<danno>, method=PLAIN, rip=71.216.71.193, lip =68.224.168.249, TLS ===== config $grep -E -v '^ *(#|$)' dovecot.conf protocols = imaps login_process_size = 64 default_mail_env = mbox:~/mail/:INBOX=/var/mail/%u mail_extra_groups = mail verbose_proctitle = yes first_valid_uid = 100 first_valid_gid = 0 mbox_read_locks = flock mbox_write_locks = flock protocol imap { imap_client_workarounds = delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep } protocol pop3 { pop3_uidl_format = %08Xu%08Xv pop3_client_workarounds = outlook-no-nuls oe-ns-eoh } protocol lda { postmaster_address = postmaster(a)example.com sendmail_path = /usr/sbin/sendmail } auth default { mechanisms = plain passdb pam { } userdb passwd { } user = root } dict { } plugin { }

[Dovecot] .imap files
by L. Scott Loftin 09 May '07

09 May '07

Dovecot version: 1.0.rc7 OS: Red Hat Fedora Core 6 CPU: x86 Filesystem: Linux I have recently upgraded from Fedora Core 4 to Fedora Core 6 (the FC6 was a clean install, not an upgrade). Prior to the upgrade, I used Dovecot to handle IMAP email that talked to Outlook clients. After the FC6 install and copying the .imap* files to the newly recreated user accounts, Outlook is not seeing the old email. Dovecot is creating new dovecot.* files to hold new email, not looking in the existing .imap.* files. Is there a way to either convert the .imap* files into the new dovecot.* files or any way to recover the email that anyone knows about? Thanks! Scott

[Dovecot] Switching from mailbox to maildir.. duplicates!
by Lars Johansen 09 May '07

09 May '07

Hi We have been running a dovecot server for some time.. users connect with pop. Now this server is going to be substituted with a new one.. before we used mbox, but now we will move to maildir! I have done some testing transfering the mail with the mb2md script, the conversion works correctly, but users gets duplicates since they selected "keep mail on server" I have googled for the problem, and set pop3_reuse_xuidl=yes and pop3_uidl_format = %08Xu%08Xv is the same on both servers.. but no luck. My first tought was to script in an X-UIDL header for each mail that was converted.. but that wont work since the mail already downloaded by the client didnt contain that header.. is there anyone that has some experience with this, or knows if its possible? Many Greetings, Lars Johansen

[Dovecot] Strange Mail Problem
by Jason Baker 09 May '07

09 May '07

I submitted this question to the Postfix maillist and they suggested that I post to this one. Here's my issue: I have a Postifx email system running on a CentOS 4 box, with Dovecot pop3 and imap. Last week, one of my users reported to me that about a dozen emails suddenly showed up in his in box (as unread messages), but none of them were addressed to him. Under further investigation, they turned out to be from another user's inbox. The messages were all over a month old. How could mail simply show up in one inbox from another user's? We're using Mozilla Thunderbird 1.5. Anyone else run into issues like this? -- *Jason Baker */IT Coordinator/ *Glastender Inc.* 5400 North Michigan Road Saginaw, Michigan 48604 USA 800.748.0423 Phone: 989.752.4275 ext. 228 Fax: 989.752.4444 www.glastender.com <http://www.glastender.com> -----BEGIN GEEK CODE BLOCK----- Version: 3.1 GIT$ d- s: a C++$ LU+++$ P+ L++>L++++ !E--- W+++ N o?

[Dovecot] File Changes and IDLE
by Andy Shellam 09 May '07

09 May '07

Hi Timo and all, I used to use Dovecot back in the 0.99 days a couple of years ago, had since moved to Courier IMAP, but with the release of Dovecot 1.0.0, I'm looking at moving back! One thing I currently have set up and working with Courier is the use of the enhanced IDLE mode, whereby Courier uses FAM (File Alteration Monitor) to monitor changes in the INBOX, and sends the details to the client as soon as a new mail arrives. Is this something that Dovecot supports? If possible, I'd prefer not to use FAM, as it crashes at random intervals and I have to keep restarting it. When I configured Dovecot, it said "File change notification method ..... : none". Does this mean FreeBSD doesn't support any method of notifying of file changes? Is there any way I can install, or re-configure the kernel, to include this support? Thanks, Andy

by Don O'Neil 09 May '07

09 May '07

I have a user that has a password that has {} in it (left and right curly brackets). Under earlier versions of dovecot (less than v1) there weren't any problems with it. Now that we've upgraded to v1, his password no longer work. The short term solution is for him to change his password, which he has. Has anyone else seen this same problem? It seems to pop up more when using webmail apps such as Squirrelmail or Uebiumaiu. Thanks!

[Dovecot] Moving new email from the mail spool to the inbox
by Adrian Barker 09 May '07

09 May '07

We are considering switching from the Washington UW IMAP server to Dovecot for performance reasons, but we make use of the feature in the UW server that automatically moves new email from the mail spool to the IMAP INBOX. Has anyone implemented this in Dovecot, or considered implementing it ? We have a large number of users, so cannot easily change the way that we deliver email. -- Adrian Barker, Information Systems University College London, Gower Street, London WC1E 6BT External phone: +44 20 7679 5140, Fax (+44) 20 7388 5406 Email: A.Barker(a)ucl.ac.uk

[Dovecot] troubleshooting new dovecot installation

Hello, I'm setting up a new mail server using freebsd 6.2, postfix, dovecot with SASL and, eventually, squirrelmail. I've gone through http://wiki.dovecot.org/TestPop3Installation the program is running, plain works over telnet from local host or from a remote machine. I can do stat and retr commands. however, when I try to use the login method (that is what the command 1 login username password part is, isn't it?) all I get is: -ERR Unknown command. even with auth_verbose = yes auth_debug = yes, logs give no information.

Re: [Dovecot] What would you tell the CIO in an "ABCs of Email" overview?
by Kenneth Porter 08 May '07

08 May '07

Perhaps the first fundamental is that Internet email isn't handled by one kind of server. It's a suite of protocols that are served by distinct processes. At minimum, you have inbound (POP3, IMAP) and outbound (SMTP) servers. You may also have a separate authentication server (LDAP) and perhaps other pieces providing calendaring, web mail (HTTP), and central storage of client configuration (ACAP). The different protocols exist not because some programmer thought it would be cool to create a new protocol, but because they serve completely different needs. For example, POP3 was designed to support lightweight disconnected clients. IMAP provides server-based storage of mail folders. LDAP provides authentication not just for mail systems but for many other applications. (I'm sure experts for each of these protocols could provide better explanations. The RFC for each probably has a motivation section that you can quote.) An important "slide" in the presentation would show the plumbing that ties all these protocols and processes together and shows how mail moves through the system. In some cases the plumbing itself is variable. For example, spam and virus processing might occur within several servers or within a client.

[Dovecot] sieve parse error
by Matthias Kellermann 06 May '07

06 May '07

Hello everyone, I'm using Dovecot (v1.0.beta3-3ubuntu5.4 under Ubuntu) with postfix and LDA with virtual users. Everything is working fine. To filter mails I use the Dovecot Sieve feature. But I get some strange error for one simple Sieve script: ---------------------------------------------------------------------------------------------------- require "fileinto"; if header :contains ["to", "Cc", "Bcc"] ["freewrt-users(a)freewrt.org"] { fileinto "Mailinglists.FreeWRT"; stop; } elseif header :contains ["to", "Cc", "Bcc"] ["getmail(a)discworld.dnsalias.org"] { fileinto "Mailinglists.getmail"; stop; } ---------------------------------------------------------------------------------------------------- This is the error I get in mail.log: ---------------------------------------------------------------------------------------------------- May 6 15:47:08 gehirnschnecke deliver: sieve parse error for matthias(a)adminlife.net: line 8: syntax error, unexpected IF, expecting '{' ---------------------------------------------------------------------------------------------------- After studying sieve.info my sieve script should be correct. What could be wrong here? Thanks & best regards Matthias

Re: [Dovecot] sporadic slow/non response, problems copying to, sent folder

This kind of behavior looks like a network issue. > You called it. We access the server over the Internet. How did I forget to provide that small detail? However, that's not the slowness I speak of. Perhaps a better term is long delay, like waiting on some timeout, before message loadding (in symptom 1., above). So are there parameters to tune, that will make dovecot behave nicer? I do not believe this to be connectivity outages between our clients and the server. For one, we never experienced these symptoms with UW-IMAP. I just duplicated the stall on copying to Sent folder. This is probably the more prevalent, and annoying of the two problems. facts: * There was only one active client. * The client was T'bird, v1.5.0.10, running on XP. * This particular test had a 3Mb attachment. * The mail was delivered immediately to the single, remote recipient (after a ~20 seconds of 3Mb upload). * The "Copying to Sent Folder" dialog stayed up for (no exaggeration) 15-minutes, and then completed; the message is in the Sent folder now. suspicion, from months of experiencing the behavior: * Attachments are usually involved. How does the config look? Are the mbox lock settings appropriate? I was somewhat shooting in the dark there. * Sendmail 8.13.6/8.13.6 * $sudo sendmail -bt -d0.10 < /dev/null | grep HASFLOCK OS Defines: BSD4_4_SOCKADDR HASFCHOWN HASFCHMOD HASFLOCK mbox_read_locks = flock mbox_write_locks = flock What else can I provide? netstats? tcpdumps? Are there logs/debugging appropriate to enable? Thanks for any ideas, Danno

[Dovecot] Method to globally limit network access
by Marcus O. White 05 May '07

05 May '07

G'day All, I am new to dovecot. I've run across the "allow_net" to restrict access on what seems like a per user basis. Is the a way to global limit access to one or more networks? Marcus O.
