[Dovecot] Postfix dovecot SASL and LDAP not working...
by Brice Figureau 12 Apr '06

12 Apr '06

Hi, I'm trying to setup a new mail server where postfix 2.3-20060405 would use Dovecot's SASL and users located in LDAP. It's with dovecot-1.0-beta5. On the postfix side, I followed the SASL_README and have the following in main.cf: smtpd_sasl_type = dovecot smtpd_sasl_path = private/auth smtpd_sasl_auth_enable = yes On the dovecot side I have the following related to auth: auth_verbose = yes auth_debug = yes auth_debug_passwords = yes auth default { mechanisms = plain digest-md5 cram-md5 # LDAP database passdb ldap { # Path for LDAP configuration file, see /etc/dovecot/dovecot-ldap.conf for # example args = /etc/dovecot/dovecot-ldap.conf } # LDAP database userdb ldap { # Path for LDAP configuration file, see /etc/dovecot/dovecot-ldap.conf for # example args = /etc/dovecot/dovecot-ldap.conf } userdb prefetch { } user = root ## ## dovecot-lda & postfix SASL specific settings ## socket listen { master { path = /var/run/dovecot-auth-master mode = 0666 } client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = postfix } } pop or imap authentification with LDAP works fine: Apr 11 17:43:08 localhost dovecot: auth(default): client in: AUTH^I1^IPLAIN^Iservice=IMAP^Isecured^Ilip=127.0.0.1^Irip=127.0.0.1^Iresp=AGJyaWNlAHRvdG8= Apr 11 17:43:08 localhost dovecot: auth(default): ldap(raymond,127.0.0.1): base=ou=people, dc=daysofwonder, dc=com scope=subtree filter=(&(objectClass=CourierMailAccount)(uid=raymond)) fields=uid,userPassword,homeDirectory,uidNumber,gidNumber,mailbox Apr 11 17:43:08 localhost dovecot: auth(default): ldap(raymond,127.0.0.1): uid(user)=raymond userPassword(password)={PLAIN}toto homeDirectory(userdb_home)=/home/raymond uidNumber(userdb_uid)=1000 gidNumber(userdb_gid)=1000 mailbox(userdb_mail)=/home/raymond/Maildir Apr 11 17:43:08 localhost dovecot: auth(default): client out: OK^I1^Iuser=raymond^I Apr 11 17:43:08 localhost dovecot: auth(default): master in: REQUEST^I1^I15439^I1 Apr 11 17:43:08 localhost dovecot: auth(default): ldap(raymond,127.0.0.1): base=ou=people, dc=daysofwonder, dc=com scope=subtree filter=(&(objectClass=CourierMailAccount)(uid=raymond)) fields=homeDirectory,uidNumber,gidNumber,uid,mailbox Apr 11 17:43:08 localhost dovecot: auth(default): master out: USER^I1^Iraymond^Isystem_user=raymond^Ihome=/home/raymond^Iuid=1000^Igid=1000^Imail=/home/raymond/Maildir Apr 11 17:43:08 localhost dovecot: imap-login: Login: user=<raymond>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured postfix SASL doesn't work, but more important don't print any debug messages, nor try to contact the LDAP server at all: Apr 11 18:00:59 localhost postfix/smtpd[15637]: connect from localhost.localdomain[127.0.0.1] Apr 11 18:01:13 localhost dovecot: auth(default): client in: AUTH^I3^Iplain^Iservice=smtp^Iresp=YnJpY2UAYnJpY2UAdG90bw== Apr 11 18:01:14 localhost dovecot: auth(default): client out: FAIL^I3^Iuser=raymond Apr 11 18:01:14 localhost postfix/smtpd[15637]: warning: localhost.localdomain[127.0.0.1]: SASL plain authentication failed: I tried several variations of the config, like without userdb prefetch, moving postfix socket config block in another auth block... Nothing worked. Since the samples are mentioning only pam as userdb and passdb source, maybe it can't work with LDAP ? Any idea on how to solve this issue ? Thanks, Regards, -- Brice Figureau

[Dovecot] DON'T DELETE THIS MESSAGE?
by Knute Johnson 12 Apr '06

12 Apr '06

I have a new install of FC5 running dovecot 1.0.0 beta 2.7. I get my mail with POP3 but I have a user using IMAP. They both work great but I keep getting a message from dovecot in my mail saying DON'T DELETE THIS MESSAGE -- FOLDER INTERNAL DATA. I think it is there to help keep track of IMAP messages. Since I use POP3 is there any way not to have it show up all the time? I've deleted it, I've deleted my account and re-added it but it keeps coming back. Dovecot is also making a 'mail' directory in my ~ that I don't think I need. What can I do about this? Thanks, -- Knute Johnson Molon Labe...

[Dovecot] IMAPS - timeout while moving mails
by Petar Bogdanovic 12 Apr '06

12 Apr '06

Hi, I'm using Dovecot v1.0.beta5 (NetBSD 3.0, i386) and Mozilla Thunderbird 1.5 (XP, i386). My dovecot.conf is pretty simple, because I just use dovecot for me as the only user. However, when I try to move a 'larger' amount of mails (>200) from my local TB-mbox to the remote IMAPS-storage, the process hangs after about 150 - 160 transferred mails (the 'blocking' mail is _never_ the same). I don't have the slightest clue why - there is nothing in the logs - even if I turn 'verbose_ssl' on. After a while, TB tells me, that the server timed out and dovecot says: "imap(petar): Disconnected" Usually - if I close my MUA correctly - dovecot says: "imap(petar): Disconnected: Logged out" Is somebody maybe experiencing something similar? Thank you very much & with kind regards, Petar Bogdanovic

[Dovecot] 1.0beta5 released
by Cesar Mesias 12 Apr '06

12 Apr '06

Dear friends, I am trying to upgrade dovecot 1.0-alpha3 to dovecot 1.0-beta 5, but I have some problems to do that. When I install its rpm I get a message which indicates I have to install some dependences such as openssl-0.9.7f-7.i386, sqlite-3.2.8-1.9.el4 and libk5crypto.so.3. I haven't had any problems with openssl and sqlite but I always get a message that I need to have the libraries of libk5crypto. I realised that I have these libraries, but I get the same message, which is the following: [root@server]rpm -ivh openssl-0.9.7f-7.i386.rpm warning: openssl-0.9.7f-7.i386.rpm: V3 DSA signature: NOKEY, key ID 4f2a6fd2 error: Failed dependencies: libk5crypto.so.3(k5crypto_3_MIT) is needed by openssl-0.9.7f-7.i386 libkrb5.so.3(krb5_3_MIT) is needed by openssl-0.9.7f-7.i386 I appreciate so much if you could send me the steps that I have to do to make the upgrade without problems. I have Red Hat Enterprise Linux 4.0 I am looking forward from hearing you soon. Thanks for your time. Regards, Cesar

[Dovecot] beta5 no ssl (imaps) connection
by Elimar Riesebieter 11 Apr '06

Hi all, running beta 5 doesn't allow ssl connections: SASL authentication failed Same config runs well with beta3. I tried as well latest CVS, but this gives me the same error. Verbose debug output: dovecot: 2006-04-09 17:17:51 Info: auth(default): client in: AUTH 1 PLAIN service=IMAP secured lip=192.168.200.1 rip=192.168.200.202 dovecot: 2006-04-09 17:17:51 Info: auth(default): client out: CONT 1 dovecot: 2006-04-09 17:17:51 Info: auth(default): client in: CONT<hidden> dovecot: 2006-04-09 17:18:51 Info: imap-login: Disconnected: Inactivity: method=PLAIN, rip=192.168.200.202, lip=192.168.200.1, TLS If I logged in on the dovecot server itself, the connection is estabilished. I guess it's only a change in the config, but which? Elimar -- Do you smell something burning or ist it me?

[Dovecot] phantom new mail (mailboxes keep on being reported as having new mail)
by Grobian 11 Apr '06

11 Apr '06

Hi, I'm using dovecot 1.0_beta3 on Gentoo Linux, and am experiencing a problem of what I call 'phantom mail'. This problem I have for a long time (pre 1.0), but at the moment I'm using 1.0_beta3 and the problem still is in there. My setup is as follows: - regular x86 box - running Exim and Dovecot - Exim saves new mail in maildir format in a local filesystem /mail/user/blabla - Dovecot reads and serves IMAP from local filesystem /mail/user/blabla - client is Mutt and/or Thunderbird from any OS (Mac, Linux, Windows) via IMAP Situation that happens: I get new mail in a folder, say =news (in Mutt style, it's .news dir in the maildir directory). I read the item, Mutt (or Thunderbird) marks the item as read (moving it over to cur aswell I think), save the folder, then move on to another folder. At this point dovecot IMAP server indicates to the client that there is new mail in the folder =news. If I visit the folder with the client, I see no new mail, and sometimes I have two or three of those folders, and I can keep on cycling with Mutt till I get bored :). Before upgrading Dovecot, I knew of no way to resolve this problem; eventually, it seemed that at some point the folder seemed to figure out itself that there was indeed no new mail. Sometimes I could trick it by letting Mutt mark the mail as new again, and then save the folder. Didn't always work. Now, I think a week or two ago I upgraded Dovecot and had to manually move all the .subscription files, and I also in one go decided to remove the dovecot* and .imap* files. That cleaned up, and at first that looked like it solved my problem. Not. So I figured out throwing away dovecot's index stuff (rm dovecot* in the directory that shows phantom mail) resolves the problem. However, this method starts to get annoying so to say. So, I did some investigation and found out that the dovecot-uidlist file seems to be not up-to-date on a folder that shows phantom mails: # awk '{ print $2 }' dovecot-uidlist | sort > tmp.uids # ls cur | sort | diff -u - tmp.uids --- - 2006-03-08 17:45:26.428168000 +0100 +++ tmp.uids 2006-03-08 17:45:19.000000000 +0100 @@ -47,4 +47,5 @@ 1141340181.H111425P8973.hermes.orakel.ods.org:2,S 1141387968.P13010Q0M35974.hermes:2,S 1141528391.H769531P12886.hermes.orakel.ods.org:2,S -1141830301.H349821P23427.hermes.orakel.ods.org:2,S +1141544380 +1141830301.H349821P23427.hermes.orakel.ods.org It seems the dovecot uidlist doesn't have the right name for the file on disk, probably therefore "seeing" a new file all the time and reporting the folder as having new mail. The 1141544380 entry comes from the first row of the dovecot-uidlist file: 1 1141544380 51 I guess it's just some sort of line to keep track of the last timestamp and the number of messages or something. If my theory is right here then it looks as if the 'bad entry' is actually more recent than this most recent timestamp reports. But this is only speculation of course. Enough for this lenghty mail I guess. Is this a known issue, or can it be caused by the way I set up my system? I must note that this only happens for some folders, not all of them. I have folders which get a lot of mail, but don't have this happening on. Any clues go resolve this are welcome. Regards, -- Fabian Groffen
