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

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

[Dovecot] SSHA Password Hashing
by Gavin Young 11 Apr '06

11 Apr '06

We are currently running a production mail server using version 0.990.99.11-2 (latest RPM from RHEL/CentOS). We would like to migrate more virtual domains off our courier imap server to dovecot but the courier imap user passswords are stored in LDAP and are SSHA hashed which is not supported by our current version of dovecot (CRYPT only). >From reading the mailing lists this feature is now available but I am hesitant to move a production server to a beta software release. Apart from waiting for a 1.0-final RPM, what is the simplest/best way for us to allow dovecot to read existing SSHA hashed passwords within LDAP? Any help would be much appreciated. Gavin

[Dovecot] anyone running with Horde mail?
by interfaSys sàrl - Rich Internet Applications 10 Apr '06

10 Apr '06

We have the exact same problem. Everything is fine with beta3, but the latest betas have problems with Horde. We are using FreeBSD and Horde 3.1. The logs show connections from 127.0.0.1. Login is successful, but the user is immediately disconnected.

Before trying to Luis' suggestion, I had the following in /var/log/messages: dovecot(pam_unix)[4691]: check pass; user unknown dovecot(pam_unix)[4691]: authentication failure; logname= uid=0 euid=0 tty= ruser= rhost= dovecot-auth[4691]: pam_ldap: could not open secret file /etc/ldap.secret (No such file or directory) I suppose the first two entries are the lookup for the dovecot user in the DS, where it doesn't exist. And since I want anonymous binds to the DS, I haven't created file /etc/ldap.secret. Users were able to authenticate and get their mail. After changing to auth_userdb = passwd, all the messages went away, but the users weren't able to get their mail: Evolution gave me the following error: "Unable to get a valid greeting" from the mailserver. I went back to auth_userdb = ldap /etc/dovecot-ldap.conf, and then back to auth_userdb = passwd. Users can get their mail, but the messages are back in the log file. I'd appreciate help in understanding this behavior. -- Oscar A. Valdez

[Dovecot] Test version for production servers for shared folders
by Gavin Henry 10 Apr '06

10 Apr '06

Dear List, Is the latest test version suitable for production systems? Our current servers use 0.99 on FC4 and we would like to add shared folders via the test version. Has anyone migrated this way before? Thanks, Gavin. -- Kind Regards, Gavin Henry. Managing Director.

Hello. Typical log text - top=0/0, retr=0/ del=0/0, size=0 I can figure out what means retr=0/ del=0/0, size=0, but what about top=0/0? It's static data, haven't seen any others numbers, than zeros there? -- Sysadmin
