[Dovecot] unable to connect to auth server
by Steven F Siirila 16 Mar '07

16 Mar '07

Upon rebooting our Dovecot server, I got these: Mar 16 09:49:16 peridot.tc.umn.edu dovecot: [ID 195972 local6.info] Dovecot v1.0.rc27 starting up Mar 16 09:49:18 myhost.mydomain dovecot: imap-login: Can't connect to auth server at default: Connection refused Mar 16 09:49:18 myhost.mydomain last message repeated 1 time Mar 16 09:49:18 myhost.mydomain dovecot: pop3-login: Can't connect to auth server at default: Connection refused Mar 16 09:49:18 myhost.mydomain dovecot: imap-login: Can't connect to auth server at default: Connection refused Mar 16 09:49:18 myhost.mydomain last message repeated 2 times Mar 16 09:49:18 myhost.mydomain dovecot: pop3-login: Can't connect to auth server at default: Connection refused Mar 16 09:49:18 myhost.mydomain last message repeated 2 times Mar 16 09:49:18 myhost.mydomain dovecot: imap-login: Can't connect to auth server at default: Connection refused Mar 16 09:49:18 myhost.mydomain last message repeated 1 time Mar 16 09:49:18 myhost.mydomain dovecot: pop3-login: Can't connect to auth server at default: Connection refused Mar 16 09:49:18 myhost.mydomain dovecot: imap-login: Can't connect to auth server at default: Connection refused However, everything does work okay. I believe we ran into this once before and reported it and I had thought Timo fixed it. It seems that imap-login and pop3-login attempt to connect to the auth server before it is fully operational. I don't recall what the fix was supposed to change, but it doesn't seem to have fully fixed it.

[Dovecot] crypt missing (configure problem)
by Fabio Busatto 16 Mar '07

16 Mar '07

Hi, I need some feedback for the following problem I encountered compiling dovecot. It seems to be a wrong check in configure, that comes out in a fatal error (crypt symbol not found because the -lcrypt is omitted). With these configure parameters no crypt module is recognized (and so the need_crypt variable is still off), but at compile time gcc fails to create executables. I solve the issue forcing the need_crypt variable to on in configure, but maybe it can be solved clearly adding the right checks. Here is some info: Dovecot: tested on 1.0.rc17 and 1.0.rc27 OS: linux Configuration parameters: ./configure --without-passwd \ --without-passwd-file \ --without-shadow \ --without-pam \ --without-bsdauth \ --without-gssapi \ --without-sia \ --without-ldap \ --without-vpopmail \ --without-static-userdb \ --without-sql \ --without-pgsql \ --without-mysql \ --without-sqlite \ --without-deliver \ --without-sql-drivers \ --with-storages=maildir \ --disable-ipv6 Here there are the errors: Making all in auth make[3]: Entering directory `/usr/src/dovecot-1.0.rc27/src/auth' /bin/sh ../../libtool --tag=CC --mode=link gcc -std=gnu99 -g -O2 -Wall -W -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -Wformat=2 -Wbad-function-cast -export-dynamic -o dovecot-auth auth.o auth-cache.o auth-client-connection.o auth-master-connection.o auth-master-listener.o auth-module.o auth-request.o auth-request-handler.o auth-stream.o auth-worker-client.o auth-worker-server.o db-ldap.o db-sql.o db-passwd-file.o main.o mech.o mech-anonymous.o mech-plain.o mech-login.o mech-cram-md5.o mech-digest-md5.o mech-ntlm.o mech-gssapi.o mech-rpa.o mech-apop.o passdb.o passdb-blocking.o passdb-bsdauth.o passdb-cache.o passdb-ldap.o passdb-passwd.o passdb-passwd-file.o passdb-pam.o passdb-checkpassword.o passdb-shadow.o passdb-sia.o passdb-vpopmail.o passdb-sql.o userdb.o userdb-blocking.o userdb-ldap.o userdb-passwd.o userdb-passwd-file.o userdb-prefetch.o userdb-static.o userdb-vpopmail.o userdb-sql.o libpassword.a ../lib-settings/libsettings.a ../lib-ntlm/libntlm.a ../lib-sql/libsql.a ../lib/liblib.a -export-dynamic -ldl gcc -std=gnu99 -g -O2 -Wall -W -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -Wformat=2 -Wbad-function-cast -o dovecot-auth auth.o auth-cache.o auth-client-connection.o auth-master-connection.o auth-master-listener.o auth-module.o auth-request.o auth-request-handler.o auth-stream.o auth-worker-client.o auth-worker-server.o db-ldap.o db-sql.o db-passwd-file.o main.o mech.o mech-anonymous.o mech-plain.o mech-login.o mech-cram-md5.o mech-digest-md5.o mech-ntlm.o mech-gssapi.o mech-rpa.o mech-apop.o passdb.o passdb-blocking.o passdb-bsdauth.o passdb-cache.o passdb-ldap.o passdb-passwd.o passdb-passwd-file.o passdb-pam.o passdb-checkpassword.o passdb-shadow.o passdb-sia.o passdb-vpopmail.o passdb-sql.o userdb.o userdb-blocking.o userdb-ldap.o userdb-passwd.o userdb-passwd-file.o userdb-prefetch.o userdb-static.o userdb-vpopmail.o userdb-sql.o -Wl,--export-dynamic libpassword.a ../lib-settings/libsettings.a ../lib-ntlm/libntlm.a ../lib-sql/libsql.a ../lib/liblib.a -ldl libpassword.a(mycrypt.o)(.text+0x5): In function `mycrypt': /usr/src/dovecot-1.0.rc27/src/auth/mycrypt.c:20: undefined reference to `crypt' collect2: ld returned 1 exit status make[3]: *** [dovecot-auth] Error 1 Making all in util make[3]: Entering directory `/usr/src/dovecot-1.0.rc27/src/util' /bin/sh ../../libtool --tag=CC --mode=link gcc -std=gnu99 -g -O2 -Wall -W -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -Wformat=2 -Wbad-function-cast -o dovecotpw dovecotpw.o ../auth/libpassword.a ../lib-ntlm/libntlm.a ../lib/liblib.a -export-dynamic -ldl gcc -std=gnu99 -g -O2 -Wall -W -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -Wformat=2 -Wbad-function-cast -o dovecotpw dovecotpw.o -Wl,--export-dynamic ../auth/libpassword.a ../lib-ntlm/libntlm.a ../lib/liblib.a -ldl ../auth/libpassword.a(mycrypt.o)(.text+0x5): In function `mycrypt': /usr/src/dovecot-1.0.rc27/src/auth/mycrypt.c:20: undefined reference to `crypt' collect2: ld returned 1 exit status make[3]: *** [dovecotpw] Error 1 Bye Fabio -- Fabio Busatto <fabio.busatto(a)sikurezza.org>

[Dovecot] BUG: Unexpected input from auth master:
by Justin McAleer 16 Mar '07

16 Mar '07

deliver logs the error in the subject whenever the userdb lookup fails. I had a query discrepancy between postfix and dovecot, so messages were accepted that shouldn't have been, but I figured deliver should probably handle that a bit more gracefully :)

[Dovecot] sasl authentication via dovecot
by Frank Church 16 Mar '07

16 Mar '07

I am setting up a Postfix/Dovecot/Virtual Domains system, with virtual tables using Postfixadmin and MySQL. Incoming mail is accepted for the virtual mailboxes, but when I try to retrieve mail from Outlook or Thunderbird I get errors You cannot log in to abc.server.net because the server has disabled login. You may need to connect via SSL or TLS. Please check the account settings for your mail server As Dovecot is handling the auth I suspect that it is where the problem lies. Are they any faults in the settings below that could be the cause? As I understand it because Dovecot is handling the login and monitoring the IMAP and POP ports. All the initial authentication is supposed to be handled there before Postfix gets involved. Running lsof -i:port on ports 110, 143, 993 and 995 shows that dovecot is handling all those inbound connections. I am also seeing messages in the log as follows dovecot: imap-login: Aborted login: rip:81.150.x.x, lip=66.90.x.x my auth section in Dovecot is as follows auth default { mechanisms = plain login passdb sql { args = /etc/dovecot/sql.conf } userdb sql { args = /etc/dovecot/sql.conf } userdb prefetch { } user = nobody socket listen { master { # path = /var/run/dovecot/auth-master path = /usr/local/var/run/dovecot/auth-master mode = 0660 user = vmail group = mail } client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = mail } } } My sql.conf is as follows driver = mysql connect = host=localhost dbname=postfix user=dovecot password=password user_query = SELECT concat('/var/vmail/', maildir) as home, concat('maildir:/var/vmail/', maildir) as mail, 601 AS uid, 12 AS gid, concat('dirsize:storage=', quota) AS quota FROM mailbox WHERE username = '%u' AND active = '1' password_query = SELECT username as user, password, concat('/var/vmail/', maildir) as userdb_home, concat('maildir:/var/vmail/', maildir) as userdb_mail, 601 as userdb_uid, 12 as userdb_gid FROM mailbox WHERE username = '%u' AND active = '1' this is the smtpd section from main.cn # ---------------------- SASL PART START ---------------------- smtpd_sasl_type = dovecot smtpd_sasl_path = private/auth smtpd_sasl_auth_enable = yes #smtpd_sasl_local_domain = $myhostname smtpd_sasl_exceptions_networks = $mynetworks smtpd_sasl_security_options = noanonymous broken_sasl_auth_clients = yes # ---------------------- SASL PART END ----------------------

[Dovecot] Warn before overquota
by Joan 16 Mar '07

16 Mar '07

Looking in the archives I found a message from dominik.saar(a)1und1.de on the 16/08/06, that is asking for a system to control the overquota warnings from within dovecot or dovecot LDA. The proposed solution is to use exim as MTA, since it has build in support. In my case I'm using postfix, what would be the recommended approach in that case? I was thinking of something like the cyrus LDA that you can with deliverquota [ -w percent ], something like that in a quota aware LDA would be quite useful for me. Any proposed solution would be welcome. Thanks

[Dovecot] running DC and UWIMAP on the same box
by Stewart Dean 15 Mar '07

15 Mar '07

It never hurts to ask...... I am bringing up DC on my production mailserver (which runs UWIMAP for production IMAP service) to learn and test it, much as I did when I introduced SSL protected IMAP, using an unpublicized non-standard port. The folder and mailbox location and format will remain the same. Questions: 1) Will DC be building indices for everything or just for the userid that I use to request client service for? 2) Are there any pitfalls others have experience doing this? -- ==== Stewart Dean, Unix System Admin, Henderson Computer Resources Center of Bard College, Annandale-on-Hudson, New York 12504 sdean(a)bard.edu voice: 845-758-7475, fax: 845-758-7035

[Dovecot] Postfix+Dovecot+LDAP
by Ejay Hire 15 Mar '07

15 Mar '07

This message does not contain a bug report or any issues. It is a summary of my experiences with Postfix, Dovecot, and Ldap. 1. Do not use Dovecot 0.99, even if it's what your vendor has packaged. 1a. ... When you upgrade past 0.99, you'll get some double mail because of UIDL's. 2. Do not use PAM and Ldap and then let dovecot talk to pam. It is bad. Don't do it. 2a. Unless you like users digging around in random mailboxes. 2b. NSCD is broken and should not be trusted. 3. Dovecot+Ldap works, and works well. 3a. If you don't do "Auth Binds", it cuts the work on the ldap server in half. 3b. User Prefetch cuts that in half again. 4. Postfix+Ldap works, and works well. 4a. If your server is underspec'd, you may get the occassional "Temporary lookup failure" 400 error during periods of heavy load, specifically when backups are running. 5. OpenLdap works. 5a. When you run as ldap, the config files need to be owned by ldap. 5b. ... And the database 5c. ... And the schema 5d. Adding slapd_db_recover to the init script isn't a bad idea. 6. Don't be dumb. 6a. ... Like me. 6b. If you are using ldap to lookup the attribute mail, index the mail attribute. 6c. If you add an index to Openldap, you have to reindex the database with slapindex 6d. ... Or you bounce a lot of mail before you figure it out. 6e. Make sure you can login to the console and/or ssh if the ldap server dies. 6f. ... Be Really sure. 6g. The convert plugin can switch users between maildirs and mboxes.

[Dovecot] tb-negative-fetch workaround
by bofh list 15 Mar '07

15 Mar '07

Hi, I notice in the Changelog that the tb-negative-fetch workaround shouldn't be needed any longer. We have a user running Thunderbird 1.5.0.8 that is experiencing the same problem described in https://bugzilla.mozilla.org/show_bug.cgi?id=263904 The current command did not succeed. the mail server responded: error in imap command uid: invalid body[..] parameter. Missing '>' in '<12288.-7215>' Any ideas? Thanks!
