[Dovecot] Problems with Dovecot and self-signed cert
by Seth Bokelman 22 Feb '05

22 Feb '05

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I've recently set up a Red Hat Enterprise Linux 4 WS server, and decided to try using Dovecot as my IMAP server, as I was impressed with the dedication to security that seems to be the core development goal. I'm really happy with it, but I can't get it to work with a self-signed cert. Normally, on a RHEL system, you just go into /user/share/ssl/certs/ and type: make whatever.pem Then you fill out the various address fields, and you've got a cert. However, when I rename/delete the existing dovecot.pem and generate a new one using this method, Dovecot won't start and I'm unable to connect to the box. The cert that it's currently using is called "localhost.localdomain", and while that works, mail clients gripe every time about the domain name not matching the certificate. I've looked through the RHEL documentation, and it appears I'm doing everything correct. Anyone have any suggestions? - -- Seth H.

Yes indeed, after trying all the various options on the mail client, i discovered that it was this "Compact" switch.

[Dovecot] uw-imap and gnu-pop3d to dovecot transition/replacement
by Jani Karlsson 22 Feb '05

22 Feb '05

Hi I am trying directly to replace old uw-imap + GNU pop3d with Dovecot. Problems I am having with new (1.0-stable 22.02.2005) are: - How to get SSL working with new config? imaps_listen doesn't exist anymore. cannot add protocol imaps for some reason. - need to get Dovecot run on another port the test-phase, ie 144 for imap, 994 for IMAPs - need to use .mailboxlist (modified the source already, this maybe works - due SSL problem not tested?) - no symlinks etc can't be done (simply too many mailboxes) so how to make dovecot read IMAP-directories from user's homedir.. Anything else I should know before trying this transition? All help truely appreciated. Jani. (Mailbox count is high which why transition to faster postclient-server software is necessary - or adding few more dual CPU-servers.. and doing anything but editing config/such by hand is not a option.)

[Dovecot] apple mail, and mails marked as deleted
by Joerg Lentsch 22 Feb '05

22 Feb '05

hi, is this a feature or a bug in conjunction with apple mail. i usually use the feature in imap to not delete the emails, but only mark them as deleted, which is a very usefull feature if you use a emailbox with more people accessing it. Im now trying an SME server installation with dovecot 0.99.10, and when i delete a message, it gets marked as deletet, but as soon as i change the mailbox the mail gets also expunged from it. is this a bug fixed in the newer dovecot releases ? or is this a feature that i can configure ?

[Dovecot] Bug?: Authentication still doesn't work with imap-login
by Peter Franck 21 Feb '05

21 Feb '05

I tried digging it all through. I can't find a solution. The problem pops up in auth-master-connection.c in function master_input_request. It does a auth_client_connection_lookup with the "client_pid" (which behaves as a counter, where i would expect a constant process-id...) Something is very wrong with this PID. Maybe someone can explain the Master <--> Auth IPC to me so I can understand and fix it myself? Where does Master take this client number from?

[Dovecot] Dovecot SSL-Certificate
by Adam Pordzik 21 Feb '05

21 Feb '05

Hello, I've a not really dovecot specific problem with my certificate. Since the OpenSSL documentation isn't what I expect to be at least good, I hope someone here can give me a hint how/where fo fix it; I've created a root-Certificate with almost untouched openssl.cnf and issued a server-certificate for dovecot. This cert and it's key I placed in somewhat like /var/dovecot. To state explicitly, away from it's superior root-cert. So, a: openssl s_client -connect server.tektoform.lan:993 -showcerts ends up in: unable to get local issuer certificate. Althougt connections from clients are working, I prefer to set it up cleanly. Does openssl-clientlib looks up for openssl.cnf, where the place of root-CA-cert is denoted, or do I have to put all cert together in a single directory, or, or, or ...? Or to be more verbose for "openssl s_client": CONNECTED(00000003) depth=0 /C=DE/ST=Hamburg/L=Hamburg/O=d-dt/OU=lan/CN=server.tektoform.lan/emailAddress=hostmaster(a)tektoform.lan verify error:num=20:unable to get local issuer certificate verify return:1 depth=0 /C=DE/ST=Hamburg/L=Hamburg/O=d-dt/OU=lan/CN=server.tektoform.lan/emailAddress=hostmaster(a)tektoform.lan verify error:num=27:certificate not trusted verify return:1 depth=0 /C=DE/ST=Hamburg/L=Hamburg/O=d-dt/OU=lan/CN=server.tektoform.lan/emailAddress=hostmaster(a)tektoform.lan verify error:num=21:unable to verify the first certificate verify return:1 --- Thanks for your comments.

[Dovecot] login: Missing protocol from server name 'imap'
by Peter Franck 20 Feb '05

20 Feb '05

I also tried the 0.99 and hacking login-process.c, with no success. It seems to expect a slash delimited string like 'name/protocol' and it just gets "imap" there, but I didn't figure out where this string comes from or what it ought to be. So I would be grateful if someone could enlighten me.

[Dovecot] Re: Need 2 additional folders like INBOX for JUNK and INFECTED mails
by Mirko Schulze 17 Feb '05

17 Feb '05

Hi there. I've solved now the problem, but it's not really fine yet. The "special-folders" are undeletable in the filesystem, but the Mailclient displays different errormessages for the same action. I've modified following source files. The new additional lines are similar to the INBOX "lines" /src/imap/cmd-list.c: 63 /src/imap/cmd-delete.c :20 /src/lib-storage/index/maildir/maildir-storage: 294,308,437,601 Notice that the linenumbers are not really correct, because of the deferrals by inserting new sourcecode. The new problem is, that the mailclient displays incorrect error messages. When i use another folder caching method i'll get no errors. Perhaps someone has a better solution, than i? Thanks Mirko

[Dovecot] Problems with MySQL/PAM authentication
by Allan Joergensen 17 Feb '05

17 Feb '05

Hi, I'm using (or trying to at least) a combination of PAM/passwd and MySQL authentication: auth vmail { mechanisms = plain userdb = sql /etc/dovecot/dovecot-sql.conf passdb = sql /etc/dovecot/dovecot-sql.conf user = root } auth system { mechanisms = plain userdb = passwd passdb = pam imap user = root } MySQL authentication works without problems but authentication real (system) users dosn't: Feb 13 02:05:57 coredump dovecot: auth(vmail): sql(alj,127.0.0.1): query: SELECT crypt AS password FROM passwd WHERE id = 'al j' Feb 13 02:05:57 coredump dovecot: auth(vmail): sql(alj,127.0.0.1): unknown user Feb 13 02:05:57 coredump dovecot: auth(system): userdb(alj,127.0.0.1): uid=10000 gid=1000 home=/home/alj mail= Feb 13 02:05:57 coredump dovecot: imap-login: Login: alj [127.0.0.1] Feb 13 02:05:57 coredump dovecot: auth(system): userdb(alj,127.0.0.1): uid=10000 gid=1000 home=/home/alj mail= Feb 13 02:05:57 coredump dovecot: imap-login: Login: alj [127.0.0.1] Feb 13 02:05:57 coredump dovecot: auth(system): userdb(alj,127.0.0.1): uid=10000 gid=1000 home=/home/alj mail= Feb 13 02:05:57 coredump dovecot: imap-login: Login: alj [127.0.0.1] Feb 13 02:05:57 coredump dovecot: auth(system): userdb(alj,127.0.0.1): uid=10000 gid=1000 home=/home/alj mail= Feb 13 02:05:57 coredump dovecot: imap-login: Login: alj [127.0.0.1] Feb 13 02:05:57 coredump dovecot: auth(vmail): file auth-client-connection.c: line 31 (auth_client_send): assertion failed: (conn->refcount > 1) Feb 13 02:05:57 coredump dovecot: auth(system): userdb(alj,127.0.0.1): uid=10000 gid=1000 home=/home/alj mail= Feb 13 02:05:57 coredump dovecot: imap-login: Login: alj [127.0.0.1] Feb 13 02:05:57 coredump dovecot: child 22359 (auth) killed with signal 6 Feb 13 02:05:58 coredump dovecot: auth(vmail): mysql: Connected to (null) (vmail) After a few logins authentication stops working and dovecot needs to be restarted.
