[Dovecot] almost there with procmail and dovecot
by M. Fioretti 30 Dec '06

30 Dec '06

Hello, I am running dovecot-1.0-0_34 on Centos 4.4 In dovecot.conf I have: default_mail_env = maildir:/var/spool/mail/vhosts/%n/%d the content of that folder is: drwxrwxr-x 3 vmail vmail 4096 Dec 30 05:23 .. drwx------ 5 vmail vmail 4096 Sep 12 13:55 .Drafts drwx------ 5 vmail vmail 4096 Dec 29 18:26 .Sent drwx------ 5 vmail vmail 4096 Dec 30 03:37 .Trash drwx------ 5 vmail vmail 4096 Dec 30 05:23 INBOX drwx------ 5 vmail vmail 4096 Dec 30 05:10 INBOX.work drwx------ 5 vmail vmail 4096 Dec 30 05:10 INBOX.family drwx------ 2 vmail vmail 8192 Dec 30 03:32 cur -rw------- 1 vmail vmail 681 Dec 30 02:38 dovecot-uidlist -rw------- 1 vmail vmail 144 Dec 30 03:32 dovecot.index -rw------- 1 vmail vmail 21504 Dec 30 03:32 dovecot.index.cache -rw------- 1 vmail vmail 110300 Dec 30 03:32 dovecot.index.log drwx------ 2 vmail vmail 4096 Dec 30 03:25 new -rw-r--r-- 1 root root 18 Dec 30 05:21 subscriptions drwx------ 2 vmail vmail 4096 Dec 30 02:34 tmp and the subscription file contains: Sent Trash Drafts For reasons not really relevant here I need to use procmail as MDA: all the INBOX* Maildir folders are created by procmail with recipes like this: MAILDIR=same as in dovecot default_mail_env :0: * ^From: dad(a)his.isp.com INBOX.family #everything else goes to: :0 * w INBOX/ The problem right now is that procmail delivers all messages correctly but the folders are invisible to squirrelmail. From its interface I can only see Sent, Trash and Drafts. Is this a folder naming problem, a configuration issue or what? How must I name those inboxes and/or reconfigure dovecot to have those folders accessible in squirrelmail? TIA, Marco

[Dovecot] cross compiling dovecot
by Martin Höfling 29 Dec '06

29 Dec '06

I have the problem that configure can't run the binaries, due to crosscompiling. How can you solve these issues with ./configure? checking whether size_t is signed... configure: error: cannot run test program while cross compiling See `config.log' for more details. I configure with a mipsel cross compiler. Cheers Martin

[Dovecot] Correct naming scheme for dovecot / squirrelmail subfolders?
by M. Fioretti 28 Dec '06

28 Dec '06

Hello, I am running dovecot 1.0-0_34.rc15 and squirrelmail 1.4.8-2 on a Centos 4 server. Right now all messages are delivered to maildir /var/mail/vhosts/virtual_mail_root/, which has its cur, tmp, new subdirectories. I need to (re) configure postfix, dovecot and squirrelmail so that email is filtered and dovecot serves different boxes to squirrelmail, that is when I log in in squirrelmail I see: Inbox work (5) friends (6) lists (35) Sent Trash Spam that is every subfolder listed under Inbox with the number of unread messages. Now, I do know how to filter incoming email in different folders with postfix. The part still missing, in spite of several online searches, is the correct _naming_ and nesting of all the new mailboxes. In other words, if now everything goes into /var/mail/vhosts/virtual_mail_root/ : 1) what is the currect _name_ to give to the future "work" inbox ?? /var/mail/vhosts/virtual_mail_root/work/ /var/mail/vhosts/virtual_mail_root/INBOX.work/ what else? 2) which parameters must be changed and how in dovecot and/or squirrelmail (or any IMAP client in my home PC) so that folders are recognized and displayed as I wish?

[Dovecot] Dovecot + Outlook express + permission denied
by Nagy László 28 Dec '06

28 Dec '06

Hello, I have an account (called awesome) that does not have access to some public shared folders. I can use this account from Mozilla Thunderbird, but I cannot use it from Outlook. I opened /var/log/maillog. When I try to list all folders, I get this in the log: Dec 28 09:57:38 designaproduct dovecot: IMAP(awesome): opendir(/var/mail/public) failed: Permission denied However, outlook displays three folders: Inbox, Public and Trash. It says "One or more problems occured downloading your list of folder from your account." That is fine, except that not all folders are listed. (There are others: "Contact", "Calendar" and "ShopzeusArchive".) Then I subscribe to "Inbox" and "Trash". I DO NOT subscribe to "Public", because the account has no access to "Public". Then I click on "Inbox" (inside outlook) and I get this very long text: Dec 28 09:57:54 designaproduct dovecot: imap-login: Login: user=<awesome>, method=PLAIN, rip=62.112.202.90, lip=195.228.74.135, TLS Dec 28 09:57:54 designaproduct dovecot: IMAP(awesome): Effective uid=1029, gid=1003 Dec 28 09:57:54 designaproduct dovecot: IMAP(awesome): Namespace: type=private, prefix=#mbox/, sep=/, inbox=yes, hidden=yes, subscriptions=no Dec 28 09:57:54 designaproduct dovecot: IMAP(awesome): mbox: data=/home/awesome/:INBOX=/var/mail/awesome Dec 28 09:57:54 designaproduct dovecot: IMAP(awesome): mbox: root=/home/awesome, index=/home/awesome, inbox=/var/mail/awesome Dec 28 09:57:54 designaproduct dovecot: IMAP(awesome): Namespace: type=private, prefix=, sep=/, inbox=no, hidden=no, subscriptions=no Dec 28 09:57:54 designaproduct dovecot: IMAP(awesome): maildir: data=/home/awesome/Maildir Dec 28 09:57:54 designaproduct dovecot: IMAP(awesome): maildir: root=/home/awesome/Maildir, index=/home/awesome/Maildir, control=, inbox= Dec 28 09:57:54 designaproduct dovecot: IMAP(awesome): Namespace: type=public, prefix=Public/, sep=/, inbox=no, hidden=no, subscriptions=no Dec 28 09:57:54 designaproduct dovecot: IMAP(awesome): maildir: data=/var/mail/public:CONTROL=/home/awesome/Maildir/public/control Dec 28 09:57:54 designaproduct dovecot: IMAP(awesome): maildir: root=/var/mail/public, index=/var/mail/public, control=/home/awesome/Maildir/public/control, inbox= Dec 28 09:57:54 designaproduct dovecot: IMAP(awesome): lstat(/var/mail/public/cur) failed: Permission denied Dec 28 09:57:54 designaproduct dovecot: IMAP(awesome): Sending log messages too fast, throttling..

Why outlook wants to open these folders? I only clicked on "Inbox", it should only open "Inbox", am I right? Outlook says "Could not select 'Inbox' on the IMAP server. You might try refreshing your folders list to synchronize with the IMAP server." But this is a lie. It tried to open many other folders, not just "INBOX". I think that my dovecot configuration is okay. I have different public and private folders. Some users can access all of them, others cannot. Using different groups of users, I can distribute permissions without problems. But I cannot make dovecot "hide" shared folders. Nor can I force all of my users to use Thunderbird. So how can I make outlook working? Thanks, Laszlo

[Dovecot] imap failed asssert in imap-bodystructure.c
by Matt Ronge 26 Dec '06

26 Dec '06

I'm running Dovecot on a Debian system which recently has been failing on an assert(). I have a spam mailbox that if I try and open (from any client), the imap process dies and this is written to the error logs: Dec 21 18:57:11 theronge imap(mronge): file imap-bodystructure.c: line 278 (part_parse_headers): assertion failed: (part->physical_pos >= input->v_offset - start_offset) Dec 21 18:57:11 theronge dovecot: child 28911 (imap) killed with signal 6 I had this same issue with my Inbox a few weeks ago, so I moved all the e-mail out and moved each piece back in one by one, in order to determine if a piece of mail was causing the issue. As soon as all my mail was moved back in, the issue went away and I was able to load my Inbox as usual. I still have the same issue with my spam mailbox, is there anything particular I can do to help debug this issue? In the past I've rm'ed all the mail in my spam mailbox and that fixes it. One thing that may be related is that I only noticed this issue after I had setup Spambayes, which does it's work via procmail. The mailboxes that I've had the issue with, all had headers that contain a Spambayes header, usually like so: X-Spam-Score: 26 X-Spam-Score: 0.6 (/) Sender: mailman-bounces(a)acm.uiuc.edu Errors-To: mailman-bounces(a)acm.uiuc.edu X-Spam-Score: 0.1 (/) X-Authenticated-Sender: X-Spam-Details: rule=cautious-plus_notspam policy=cautious-plus score=26 mlx=26 adultscore=0 adjust=0 reason=mlx engine=3.1.0-0611300000 definitions=main-0612060023 X-Spam-OrigSender: mailman-bounces(a)acm.uiuc.edu X-Spam-Bar: *** X-Spambayes-Classification: spam; 1.00 X-Spambayes-Trained: spam I'm not sure if it's related, but it's a shock in the dark on my part. Any suggested steps that might help isolate this bug? -- Matt Ronge

[Dovecot] Intermittent "cannot update mailbox" problems w/ postfix & dovecot
by John Reddy 26 Dec '06

26 Dec '06

I hate asking questions on mailing lists, but I've exhausted my googling and FAQ trawling skills. If I've missed the pertinent doc, please tell me where to RTFM. Environment: I'm running postfix 2.3.2 on a Solaris 10 server. Mail goes into standard mbox format in /var/mail. Users can access their mail via shell (pine, mutt), POP3 or IMAP, and the pop3/imap server is dovecot-1.0.rc15. Problem: For a few users, mail occasionally fails to deliver. The mail is accepted by smtpd, passes cleanup and qmgr without incident. When it gets to local delivery, though, local complains that "cannot open file: Permission denied". A sample log entry (slightly sanitized): Dec 7 09:42:05 solaris-host local[18332]: [ID 197553 mail.info] D35C3445C: to=<bubba(a)solaris-host.sample.com>, relay=local, delay=0.17, delays=0.09/0/0/0.08, dsn=5.2.0, status=bounced (cannot update mailbox /var/mail/bubba for user bubba. cannot open file: Permission denied) Dec 7 10:52:26 solaris-host local[20775]: [ID 197553 mail.info] 670C9445D: to=<jack(a)solaris-host.sample.com>, relay=local, delay=15, delays=8.9/0/0/6.5, dsn=5.2.0, status=bounced (cannot update mailbox /var/mail/jack for user jack. cannot open file: Permission denied) Does anyone have any advice on how I might get better details about why postfix is having trouble accessing the file? Has anyone run into this before? My initial suspicion is a lock file from the users' POP3 connections... Thanks in advance for any help. -John

[Dovecot] [Fwd: mbox somewhere else?]

In case it's missed :) -------- Original Message -------- Subject: [Dovecot] mbox somewhere else? Date: Tue, 19 Dec 2006 20:26:30 +0200 From: Tolga <kartagis(a)kunduz.org> To: dovecot(a)dovecot.org Hi, I want to store my folders somewhere else, it used be in ~/mail. Is this as easy as moving everything in ~/mail to /var/mail/ and editing /etc/dovecot/dovecot.conf to read mail_location=mbox:~/mail:INBOX=/var/mail/%u ? Also, is the syntax mail_location=mbox:/var/mail/%u-folders:INBOX=/var/mail/%u correct? Regards, -- Whatever it is, I fear Greeks even when they bring gifts. -- Publius Vergilius Maro (Virgil)

[Dovecot] vpopmail problem
by Toni Panadès 26 Dec '06

Hi! Sorry for my english... I recently know about dovecot and I try to use it on my server. Previously I used qmail+vpopmail+courier and now I want to use postfix+dovecot and, to mantain all my mailboxes structure, I try to use dovecot with vpopmail. During configuration the script detects my vpopmail installation and configuration and after I get this status: Install prefix ...................... : /usr/local File offsets ........................ : 64bit I/O loop method ..................... : poll File change notification method ..... : dnotify Building with SSL support ........... : yes (OpenSSL) Building with IPv6 support .......... : yes Building with pop3 server ........... : yes Building with mail delivery agent .. : yes Building with GSSAPI support ........ : no Building with user database modules . : static prefetch passwd passwd-file checkpassword vpopmail (modules) Building with password lookup modules : passwd passwd-file shadow checkpassword vpopmail (modules) And after some testing I start the daemon with this config: protocols = imap imaps pop3 pop3s auth default { mechanisms = plain passdb vpopmail {} userdb vpopmail {} user = vpopmail } I connect to localhost via pop3 and when I try to auth some user I get this: Dec 26 01:27:45 anet dovecot: auth(default): client in: AUTH 1 PLAIN service=IMAP secured lip=127.0.0.1 rip=127.0.0.1 resp=AHNyb2RvbkBncmFjaWFuZXQub3JnAHR3aXN0 Dec 26 01:27:45 anet dovecot: auth(default): vpopmail(srodon(a)anet.org,127.0.0.1): unknown user Dec 26 01:27:46 anet dovecot: auth(default): client out: FAIL 1 user=srodon(a)anet.org Dec 26 01:27:46 anet dovecot: imap-login: Aborted login: user=<srodon(a)anet.org>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured I tried other auth methods but I get an "Unsupported authentication mechanism" error.

[Dovecot] Sizing login_process_size and login_processes_count?
by Francisco Reyes 25 Dec '06

25 Dec '06

Any suggestions on sizing login_process_size and login_processes_count for a server expected to be doing 100 to 200 simultaneous connections? Is there a way to separate login_processes_count between imap and pop? I would like to have at least 50 imap processes ready, but we rarely have any more than 5 to 10 pop connections. Would be a shame to have 40+ pop login processes doing nothing most of the time. For now did login_process_size = 96, but with an average of 100 to 200 and some rare ocassion of 300+ connections I am wondering what is a reasonable number for login_process_size.
