[Dovecot] An unconstructive grumble
by dd 03 Jun '13

03 Jun '13

5 hours of configuration attempts, error after confusing error, documentation with examples that only show extracts of working configurations. I really feel like throwing in the towel with dovecot. It should not be this hard and frankly almost impossible to understand and configure for such an incedibly simple configuration. /home/vmail/domain.name/username/cur /home/vmail/domain.name/username/new /home/vmail/domain.name/username/tmp 3 virtual users. All I want is a username and password to access my email. I have to have hit every error and problem there can be. No response at all from server, unable to find password file, unable to recognise user, invalid password. God it went on and on and on for five or more hours. For such a simple config. I know this is a totally unconstructive complaint and I should be taking the time to set out a careful explanation of my problem along with errors and logfiles but I just can't be bothered. I've tried so many many configurations and options and nothing works. How can it possibly be this hard to ghet some emails off the server with simple username/password configurations. Go ahead and flame me to a crisp. -- View this message in context: http://dovecot.2317879.n4.nabble.com/An-unconstructive-grumble-tp42598.html Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] Settings: Dovecot + NTLM + Single Sing On + Windows + Outlook or Thunderbird.
by Maria Jose Yañez Dacosta 03 Jun '13

I am following the steps listed in: http://wiki.dovecot.org/HowTo/ActiveDirectoryNtlm My goal is to have single sign-on for Microsoft Outlook applications. I working and I have some doubts since I never set up an imap server, hope I can help :). The version that I have installed is devecot 2.0.9. "dovecot -n" shows the following: # 2.0.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-71.el6.x86_64 x86_64 CentOS release 6.4 (Final) auth_use_winbind = yes mbox_write_locks = fcntl passdb { driver = pam } protocols = imap pop3 ssl = no userdb { args = uid=10000 gid=10000 home=/mail/%d/%n driver = static } I show what I have in /etc/samba/smb.conf [global] workgroup = EJEMPLO realm = EJEMPLO.COM.UY server string = %h (Samba %v) security = ADS password server = ad.domain.dom username map = /etc/samba/mapeousuarios map untrusted to domain = Yes syslog = 0 log file = /var/log/samba/log.%m max log size = 1000 name resolve order = wins host bcast local master = No domain master = No dns proxy = No wins server = here active directory ip panic action = /usr/share/samba/panic-action %d winbind separator = + winbind use default domain = Yes winbind rpc only = Yes idmap config * : range = 1200-3000 idmap config * : backend = tdb [usuarios3] path = /exports/archivos-usuarios read only = No map acl inherit = Yes store dos attributes = Yes "wbinfo -g" and "wbinfo -u" work well. kinit Administrator work well also. Some steps of the configuration in dovecot.conf does not recognize: 1) "protocols = imap imaps pop3 pop3s". 2) "mechanisms = plain ntlm login". 3) "allow_all_users=yes" y "mail=maildir:/home/vmail/%d/%1Ln/%Ln:INBOX=/home/vmail/%d/%1Ln/%Ln". I'm not sure I should put in place. I also have some doubts: 1) I have to create a keytab file containing the principal for imap and pop?, as it would indicate Dovecot?. 2) That should indicate values uid y el gid? 3) I have to set something in pam? if I make "telnet localhost imap" shows the following: OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE AUTH=PLAIN] Dovecot ready NTLM not appears in the options. I hope I can shed some light on the subject :) Thanks and greetings. -- Maria José

Regarding your questions: Exchange 2010 and its supported (and unsupported and deviations from) IMAP standards are described on MS-STANXIMAP (MSDN). As far as I can tell, neither XLIST nor the enhanced (=extension of the standard) version of LIST is supported. Please keep in mind that this wouldn't matter very much, since most would connect to an Exchange 2010 server using either ActiveSync or MAPI/RPC. The following scenarios would definitely work: (A) your provider allows connections using ActiveSync (often referred to as "mobile" connection/access) and you're using Outlook 2013, (B) your provider allows connections using MAPI/RPC and you're using Outlook 2010. Outlook 2013 supports the extension specified in RFC 6154 and implements it using the XLIST command (as per MS-STANOIMAP), as documented in MS-STANOIMAP part 2.2.38; however, the LIST command in the same document doesn't mention the extension, so I'd assume it (Outlook 2013) doesn't necessarily support this feature using LIST as specified per RFC6154 (but only using explicitly XLIST.) Usually, any newer IMAP server supporting RFC6154 "LIST" ("XLIST") supports both the older XLIST as well as the newer LIST syntax. If it doesn't, a patch implementing this feature shouldn't be longer than a few (10 maybe?) lines of code and a few kind words to the developer team to get it into the next release of the server in question. --- http://msdn.microsoft.com/en-us/library/ee624430%28v=exchg.80%29.aspx ----------- V0061: The specification describes how to define an experimental command or any command that is not part of the specification. Microsoft Office Outlook 2007, Microsoft Outlook 2010 Outlook does not define any such commands. Microsoft Outlook 2013 Outlook 2013 implements the IMAP LIST extension specified in [RFC6154] as the XLIST command. --------------- so it may more a typical microsoft doku problem *g but however ,in fact no working trouble with dovecot SPECIAL-USE as far i remmeber to that list posting the problem whas there should get fixed was outlooks meaning of the Junk folder stuff, which is basicly done in another way by having its own antispam feature setup, so there are a few way to workaround that problem which i never tested and never will. My simple answer always is, Outlook is the client of exchange, with few stuff supporting normal internet mail ( imap etc ), dont use it with internet mail or live with its problems for notice Horde will implement Outlook 2013 complete active sync stack , so if that will happen, use active sync modus outlook 2013 with calender, abook, push mail , should no need for direct imap server con then, and it should "feel" like using exchnage ( but i think for one account only ), as horde has caldav and carddav , syncml too it can be used as middleware between many clients on many different os types i.e thunderbird lightning and k9 or native androids mail clients in exchange mode Best Regards MfG Robert Schetterer -- [*] sys4 AG http://sys4.de, +49 (89) 30 90 46 64 Franziskanerstraße 15, 81669 München Sitz der Gesellschaft: München, Amtsgericht München: HRB 199263 Vorstand: Patrick Ben Koetter, Axel von der Ohe, Marc Schiffbauer Aufsichtsratsvorsitzender: Florian Kirstein Best Regards MfG Robert Schetterer -- [*] sys4 AG http://sys4.de, +49 (89) 30 90 46 64 Franziskanerstraße 15, 81669 München Sitz der Gesellschaft: München, Amtsgericht München: HRB 199263 Vorstand: Patrick Ben Koetter, Axel von der Ohe, Marc Schiffbauer Aufsichtsratsvorsitzender: Florian Kirstein

[Dovecot] dovecot-lmtp does not work
by He Shiming 01 Jun '13

01 Jun '13

Dear Community, I've got a weird problem regarding lmtp setup with dovecot 2.0.19 on ubuntu 12.04.2 LTS. My reference of the configuration is at https://library.linode.com/email/postfix/postfix2.9.6-dovecot2.0.19-mysql , and my configuration is identical to it with the exception of opening the 110 pop3 port, and enabling plain text auth. Everything from imap, smtp, pop3 (including auth) works except for lmtp. I saw thousands of the following messages in /var/log/mail.log: May 31 09:05:24 postfix/lmtp[3664]: 2FD80321F4: to=<myaddress(a)me.com>, relay=none, delay=0.41, delays=0.41/0/0/0, dsn=4.4.1, status=deferred (connect to me.com[private/dovecot-lmtp]: No such file or directory) And it happens when an incoming email is received. Here's the output of configuration: root@prosp:/etc/dovecot/conf.d# dovecot -n # 2.0.19: /etc/dovecot/dovecot.conf # OS: Linux 3.8.4-linode50 i686 Ubuntu 12.04.2 LTS ext3 auth_mechanisms = plain login disable_plaintext_auth = no mail_location = maildir:/var/mail/vhosts/%d/%n mail_privileged_group = mail managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = imap pop3 sieve service auth-worker { user = vmail } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0666 user = postfix } unix_listener /var/spool/postfix/private/dovecot-auth { group = postfix mode = 0660 user = postfix } unix_listener auth-userdb { mode = 0600 user = vmail } user = dovecot } service imap-login { inet_listener imap { port = 0 } } service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0600 user = postfix } } service pop3-login { inet_listener pop3 { port = 110 } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_cipher_list = ALL:!LOW:!SSLv2:ALL:!aNULL:!ADH:!eNULL:!EXP:RC4+RSA:+HIGH:+MEDIUM ssl_key = </etc/ssl/private/dovecot.pem userdb { args = uid=vmail gid=vmail home=/var/mail/vhosts/%d/%n driver = static } protocol imap { imap_client_workarounds = delay-newmail mail_max_userip_connections = 10 } protocol pop3 { mail_max_userip_connections = 10 pop3_client_workarounds = outlook-no-nuls oe-ns-eoh } protocol lda { deliver_log_format = msgid=%m: %$ mail_plugins = sieve postmaster_address = postmaster quota_full_tempfail = yes rejection_reason = Your message to <%t> was automatically rejected:%n%r } This problem has been discussed here: http://serverfault.com/questions/512219/dovecot-lmtp-does-not-exist . I've then tried switching from unix socket to inet listener, and still got the same result. I cannot get lmtp service to start. I'm also seeing no errors in the log when dovecot is restarted (see the above link for the log). I'm wondering how do I go about troubleshooting this problem? What might be the possible cause? Is it possible for dovecot to output verbose logs regarding service startups?

[Dovecot] LDA/LMTP - saving to INBOX fallback on tempfail?
by Timo Sirainen 31 May '13

31 May '13

Currently if saving to mailbox fails for any reason, the mail is saved to INBOX instead. Same if a Sieve redirect fails, the mail is saved to INBOX. I'm wondering if anyone actually prefers this behavior when the error is temporary? For example if some index file corruption was detected, the save will most likely succeed the next time it's attempted. Or if the redirect fails because the SMTP server can't be connected to at the moment. So I was thinking about changing v2.2 LDA/LMTP to simply return temporary failure instead of saving the mail to INBOX.
