[Dovecot] Reverting from 2.0. to 1.2
by Thomas Hummel 30 Dec '10

30 Dec '10

Hello Timo, I switched this morning from dovecot-1.2.12 to 2.0.8 with a basic setup (high performance login mode, Maildir, everyhing on NFS, one shared but unused namespace). No problem so far except that some Thunderbird users who wouldn't succeed in moving messages from some one folder to another. They'd get a message about some illegal character in the mailboxname (already existing mailbox of course). This is user input so I don't have any details nor sufficient element to consider it a real problem. A Thunderbird restart seems to solve the problem. My questions were : . is there a different handling in the hierarchy separator (internal or advertized for the namespace) ? (I use "/" for both namespaces and "." since in Maildir). . is there a different handling in the non-ASCII mailbox names ? Could it be related ? . if something goes really wrong, is it safe to revert to 1.2.12 ? Maybe some files has non-compatible format (dovecot-uidlist, indexes, ...) ? Thanks. -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Pôle informatique - systèmes et réseau

[Dovecot] over quota issue
by PA 30 Dec '10

30 Dec '10

I have a situation where if a user is over quota and sending through postfix I get an error, now this error only happens if the user is over quota, otherwise it works with no problem. However if sending using /usr/local/libexec/dovecot/dovecot-lda it works every time even if overquota, any ideas? I just can't seem to figure this one out.

[Dovecot] Dovecot 1.2.12+Postfix+Active Directory: virtual domain name dropped.
by Ran Talbott 30 Dec '10

30 Dec '10

I have a Windoze-only client who wants to move their mail hosting from godaddy.com hosting to an in-house system. I'm pitching Linux as an alternative to Exchange, and trying to set up a demonstration system for them. While a long-time Linux user, my server admin experience has been in setting up front-ends (mostly Apache-based web interfaces) for the embedded systems I specialize in. The goal is to have an IMAP server where the users don't have Linux IDs, and only need to manually login to the Active Directory domain controller. The client has multiple Internet domains, but all users are in the same Active Directory realm internally. With the help of the how-tos at linuxmail.info, I got the system to the point of being able to authenticate logins for both IMAP and SMTP (usng dovecot-SASL). I tried using PAM first, but it didn't work: running kinit from the command line takes over 90 seconds to get a ticket, and Dovecot timed out after 60 on every login attempt. So I switched to LDAP. Note: I still don't understand why, but authentication through Active Directory didn't work until I changed the querying distinguished name from the "cn=,dc=,dc=" format to "user(a)xxxx.local" format. I have Postfix using dovecot-deliver as the LDA, but I hit a snag: deliver is not putting the domain name in the path to the maildir. I have the active directory query set as: user_filter = (&(objectClass=user)(samaccountname=%n)) user_attrs = =home=/var/mailstore/%d/%n. =uid=501, =gid=501, \ =mail=maildir:/var/mailstore/%d/%n/Maildir/ When I send mail to testing.testing(a)xxxx.xxx (real domain obscured), I see this in mail.log Dec 23 10:49:24 IBMUBUNTU1 dovecot: auth(default): master in: USER#0111#011testing.testing(a)xxxx.xxx#011service=deliver Dec 23 10:49:24 IBMUBUNTU1 dovecot: auth(default): ldap(testing.testing): user search: base=dc=lawley, dc=local scope=subtree filter=(&(objectClass=user) (samaccountname=testing.testing)) fields= Dec 23 10:49:24 IBMUBUNTU1 dovecot: auth(default): ldap(testing.testing): result: objectClass(?unknown?)= cn(?unknown?)= sn(?unknown?)= givenName(?unknown?)= distinguishedName(?unknown?)= instanceType(?unknown?)= whenCreated(?unknown?)= whenChanged(?unknown?)= displayName(?unknown?)= uSNCreated(?unknown?)= uSNChanged(?unknown?)= name(?unknown?)= objectGUID(?unknown?)= userAccountControl(?unknown?)= primaryGroupID(?unknown?)= objectSid(?unknown?)= sAMAccountName(?unknown?)= sAMAccountType(?unknown?)= userPrincipalName(?unknown?)= objectCategory(?unknown?)= Dec 23 10:49:24 IBMUBUNTU1 dovecot: auth(default): master out: USER#0111#011testing.testing#011home=/var/mailstore//testing.testing. =uid=501#011gid=501#011mail=maildir:/var/mailstore//testing.testing/Maildir/ i.e., the domain does not appear in the paths to the home directory or maildir. I found a bug report in the mailing list that looks like it might be the same problem (%d not supported in user_attrs), but the fix it references is for 2.0. Is this a known problem in 1.x? Is there a fix/workaround for it? E.g., could I have Postfix generate the maidir path and pass it to deliver as the "-m" parameter? Thanks, Ran

[Dovecot] Is this really a user agent issue?
by Phil Howard 30 Dec '10

30 Dec '10

I suspect this is a user agent issue, given that Evolution is flaky in so many areas. When I deliver mail to a subfolder/subbox (e.g. the -m option in the deliver command), and Evolution doesn't know of it, yet, creating it fails, and Evolution still can't get to it. Doing things the other way around (create it in Evolution first, then deliver to it) works fine. Seems to be silliness to me. Just wondered if any Dovecot aspects might be involved ... such as the fact that the case is different (e.g. "INBOX" in the filesystem, but "Inbox" in Evolution). -- sHiFt HaPpEnS!

[Dovecot] How to get a working dovecot.conf?
by oddball56 29 Dec '10

29 Dec '10

Hi, I installed openSUSE 11.3 server version, and followed the guidelines from: http://www.howtoforge.com/perfect-server-opensuse-11.3-x86_64-ispconfig-3 Everything works, accept loggin into dovecot. For many days i tried to get logged into dovecot, from localhost, from other pc in the lan, from squirrelmail, not possible. I read manuals on http://wiki.dovecot.org/ and tried to set the passwd db like: auth default { .. passdb passwd-file { args = /etc/passwd.dovecot } .. The "args" were not accepted according to the output from dovecot -n As now i installed dovecot 20, with a fresh dovecot.conf. Ofcourse this was not working, so i 'updated' ISPConfig. Now my dovecot.conf is a mess, and i get errormessages like: Dec 20 21:00:02 AsusTT-sfn6 postfix/smtpd[7073]: fatal: no SASL authentication mechanisms And from dovecot: dovecot.pem missing from /etc/ssl/certs, so no ssl login possible also Now i am checking dovecot -n line by line and this message pops out: mail_plugin_dir: access(/usr/lib/dovecot/modules/imap) failed: No such file or directory passdb { driver = pam } passdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } furtheron: ssl = no userdb { driver = passwd } userdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } it has 64 lines. first and last_valid_uid and gid are set to 5000. In this conf i did not change anything. I would realy appreciate some help, as my only goal was to set up an imap server so i can access my mail from all over the world, and have all mail in 'one' central place, instead of scattered all over many pc's and laptops. The irony is that evrything but this works ;-p tia, for an answer.

Core dumps were disabled unfortunately, so I don't know if this is helpful at all: Dec 29 15:41:58 lmtp(8853): Panic: file lmtp-proxy.c: line 370 (lmtp_proxy_output_timeout): assertion failed: (proxy->data_input->eof) Dec 29 15:41:58 lmtp(8853): Error: Raw backtrace: /usr/local/dovecot20/lib/dovecot/libdovecot.so.0 [0xb76aa7c1] -> /usr/local/dovecot20/lib/dovecot/libdovecot.so.0 [0xb76aa83f] -> /usr/local/dovecot20/lib/dovecot/libdovecot.so.0(i_error+0) [0xb76aab14] -> dovecot/lmtp [0x804e3f4] -> /usr/local/dovecot20/lib/dovecot/libdovecot.so.0(io_loop_handle_timeouts+0xe0) [0xb76b7720] -> /usr/local/dovecot20/lib/dovecot/libdovecot.so.0(io_loop_handler_run+0x8b) [0xb76b843b] -> /usr/local/dovecot20/lib/dovecot/libdovecot.so.0(io_loop_run+0x40) [0xb76b7340] -> /usr/local/dovecot20/lib/dovecot/libdovecot.so.0(master_service_run+0x2a) [0xb76a31fa] -> dovecot/lmtp(main+0x170) [0x804b380] -> /lib/i686/cmov/libc.so.6(__libc_start_main+0xe5) [0xb7516455] -> dovecot/lmtp [0x804b171] Dec 29 15:41:58 master: Error: service(lmtp): child 8853 killed with signal 6 (core dumps disabled) doveconf -n output: $ /usr/local/dovecot20/bin/doveconf -c /usr/local/dovecot20/etc/dovecot/dovecot-lmtpproxy.conf -n # 2.0.8: /usr/local/dovecot20/etc/dovecot/dovecot-lmtpproxy.conf # OS: Linux 2.6.31.5 i686 Debian 5.0.7 auth_cache_negative_ttl = 0 auth_mechanisms = plain login auth_socket_path = /usr/local/dovecot20/var/run/dovecot-lmtpproxy/auth-userdb auth_username_chars = abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@&: auth_verbose = yes base_dir = /usr/local/dovecot20/var/run/dovecot-lmtpproxy/ disable_plaintext_auth = no listen = * lmtp_proxy = yes log_path = /var/log/dovecot.lmtpproxy/dovecot.lmtpproxy.log login_log_format_elements = user=<%u> service=%s method=%m rip=%r lip=%l %c login_trusted_networks = 172.16.83.64/26 mail_fsync = never mail_gid = 1000 mail_location = maildir:~/Maildir mail_uid = 1000 maildir_very_dirty_syncs = yes passdb { args = /usr/local/dovecot20/etc/dovecot/dovecot-sql.lmtpproxy.alias.conf driver = sql } postmaster_address = postmaster(a)example.com protocols = lmtp service auth-worker { user = $default_internal_user } service auth { client_limit = 8192 unix_listener auth-userdb { mode = 0666 } } service imap-login { process_min_avail = 1 service_count = 0 vsz_limit = 1 G } service imap { process_limit = 2048 } service lmtp { inet_listener lmtp { address = * port = 24 } process_min_avail = 1 service_count = 0 user = mailuser vsz_limit = 512 M } service pop3-login { process_min_avail = 1 service_count = 0 vsz_limit = 1 G } service pop3 { process_limit = 2048 } ssl = no verbose_proctitle = yes protocol lda { info_log_path = log_path = mail_fsync = optimized } protocol imap { imap_client_workarounds = delay-newmail mail_max_userip_connections = 20 } protocol lmtp { mail_fsync = optimized } protocol pop3 { mail_max_userip_connections = 5 pop3_client_workarounds = outlook-no-nuls oe-ns-eoh }
