[Dovecot] %d not recognized with LDAP
by Anil 11 Jan '08

11 Jan '08

I saw the recent threads but didn't help for me. Here's my configuration: The domain isn't getting expanded as per logs: Jan 4 08:06:40 vds5 dovecot: [ID 107833 mail.info] IMAP(admin): maildir: data=/var/mail/apps//admin/Maildir # 20080102: /usr/local/dovecot/etc/dovecot.conf listen: *:143 ssl_disable: yes disable_plaintext_auth: no login_dir: /usr/local/dovecot/var/run/dovecot/login login_executable: /usr/local/dovecot/libexec/dovecot/imap-login login_log_format_elements: user=<%n@%d> method=%m rip=%r lip=%l %c login_max_connections: 64 max_mail_processes: 128 mail_location: maildir:/var/mail/apps/%d/%n/Maildir mail_debug: yes auth default: passdb: driver: ldap args: /usr/local/dovecot/etc/dovecot-ldap.conf userdb: driver: static args: uid=vmail gid=vmail home=/var/mail/apps/%d/%n Here's the relevant LDAP configuration: auth_bind = yes pass_attrs = uid=user pass_filter = uid=%n I tried setting the mail_location to: maildir:~/Maildir and explicitly specifying the full path, but still the Maildir is getting created with out the %d. Of course, the user is logging in with "admin(a)domain.com". Any ideas?

[Dovecot] Problems with AUTH=PLAIN in pop3
by Maykel Moya 11 Jan '08

11 Jan '08

I'm using Dovecot (1.0.10) locally to test SugarCRM. When I tried to set up a mail account in Sugar, it complains with -- SECURITY PROBLEM: insecure server advertised AUTH=PLAIN Please check your settings and try again. -- don't know if that behaviour is a bug or a feature of php-imap. The case is that I'm unable to set up the mail account in Sugar. Timo answered to me on IRC about Dovecot assuming that a connection from the same ip is considered secured. I'd rebuild Dovecot with the following patch: --- dovecot-1.0.10/src/pop3-login/client.c.orig 2008-01-05 00:44:14.000000000 -0500 +++ dovecot-1.0.10/src/pop3-login/client.c 2008-01-05 00:44:30.000000000 -0500 @@ -331,7 +331,7 @@ client->created = ioloop_time; client->refcount = 1; client->common.tls = ssl; - client->common.secured = ssl || net_ip_compare(ip, local_ip); + client->common.secured = ssl; client->common.local_ip = *local_ip; client->common.ip = *ip; --- but still not able to make it not accept AUTH PLAIN authentication from the same ip. I'm missing something? On the other hand, if I set disable_plaintext_auth to yes I cannot use the classic USER/PASS pop3 verbs. I'm not sure what the POP3 related RFCs mandates with respect to this.

[Dovecot] Imap assertion (dovecot-1.1.beta13)
by Nuno Lopes 11 Jan '08

11 Jan '08

Hi, I continue testing the beta versions and have seen a great improvement over the last few ones. On beta13 I'm seeing the following assert on some client folders: file index-mail.c: line 759 (index_mail_stream_destroy_callback): assertion failed: (mail->data.destroying_stream) If you need I can try and reproduce this in a more controled environment to pinpoint the problem. Thanks, -- Nuno Lopes

[Dovecot] Too many open files

[Dovecot] Switch from courier to dovecot
by Richard G Riley 10 Jan '08

10 Jan '08

I have an courier IMAP server running. To get sib dirs working I had to rename them all to begin with a period ".". e.g Maildir Maildir/{cur,new,tmp} Maildir/.account1/{cur,new,tmp} Maildir/.account2/{cur,new,tmp} Maildir/.account3/{cur,new,tmp} etc If I uninstall Courier and install dovecot, will these "period" dirs be seen by default? I am fairly new to this and sometimes it seems that Maildir format requirements vary a lot depending on client or server. Thank you for your help.

[Dovecot] Too many open files
by Harrison Metzger 10 Jan '08

10 Jan '08

Hello, I have dovecot installed and it works for about 3 hours then I get this error (in /var/log/maillog): Jan 8 08:42:53 stu dovecot: auth(default): pam(grossmsm,69.131.100.47): pipe() failed: Too many open files I set pam_limits.so to allow the user 'dovecot' to have 8192 open files, and I also changed: login_process_size = 512 However, it still wont work for more than a few hours. When I run: lsof -p `ps -o pid= -C dovecot-auth` I get: [...] dovecot-a 1385 root 248u sock 0,5 374241289 can't identify protocol dovecot-a 1385 root 249u sock 0,5 374241391 can't identify protocol dovecot-a 1385 root 250u sock 0,5 374243642 can't identify protocol dovecot-a 1385 root 251u sock 0,5 374241701 can't identify protocol [...] And the number followed by a u keeps growing. As of writing this email that number is now at 274u. Is dovecot not closing its fd's or something? Harrison Metzger

[Dovecot] OT: ctimes
by Jeff Grossman 10 Jan '08

10 Jan '08

I am going to convert my 32-bit Debian system to a 64-bit Debian system today. But, after I move my maildir files over to the new hard drive the ctimes are going to get modified to current time and mess up my automatic purge scripts for the Deleted Items folders. Is it possible for me to either keep the existing ctimes or is it possible for me to modify the ctimes to the date headers of the emails after I move the files? Thanks, Jeff

[Dovecot] Dovecot indexing questions
by Asheesh Laroia 10 Jan '08

10 Jan '08

I was playing with Dovecot 1.1 full text indexing through Squat in late October, which was working pretty well. I wanted to ask about this behavior I had: When an email arrives in INBOX using procmail (which delivers to my Maildirs), and I see it in Dovecot, when I next do a search (IMAP SEARCH TEXT) of that folder, the search takes a long time. Successive searches are lickety-split. My question is: Can there be an option to "index greedily"? As soon as Dovecot sees the message, I'd like it to update the Squat index. That way, searches are always fast. I guess this implies a small performance hit - namely, that my IMAP server spends CPU and disk time indexing every message at the first time it is seen rather than being able to do batch indexing each time SEARCH TEXT is issued. But when I think about that, that sounds like the server can waste its time so I don't waste mine - which is exactly why I like these computing machines! (That, and because I can waste my time programming them.) -- Asheesh. -- Use extra care when cleaning on stairs.
