[Dovecot] Dovecot 2.0.x + Sendmail 8.14.4 SMTP AUTH not working
by Serhiy Kolesnyk 31 Jul '11

31 Jul '11

Hello! After moving from Centos 5.6 to Centos 6, I figured that Sendmail minor version was updated from 8.13.x to 8.14 and Dovecto from 1.2 to 2.0.x In previous configuration SMTP auth worked fine (no SASAUTHD neccessary) for virtual users table. Dovecot was authenticating virtual users virtual checking dovecot.passwd file. I'm not sure how Sendmail was processing SMTP AUTH for virtual users connecting via email clients since there was no obvious connection to Dovecot authentication. But SMTP AUTH was working and virtual users could send email via SSL. Now after this recent upgrade I looked into Dovecot conf changes and updated it according. POP/IMAP are working and Sendmail does deliver incoming mail to the mbox folders. What stopped working is SMTP AUTH. Here's maillog excerpt of authentication process: Jul 29 23:46:11 one2action sendmail[2865]: AUTH: available mech=CRAM-MD5 DIGEST-MD5 LOGIN GSSAPI PLAIN, allowed mech=LOGIN PLAIN Jul 29 23:46:11 one2action sendmail[2865]: STARTTLS=server, get_verify: 0 get_peer: 0x0 Jul 29 23:46:11 one2action sendmail[2865]: STARTTLS=server, relay=136-31-132-95.pool.ukrtel.net [95.132.31.136], version=TLSv1/SSLv3, verify=NO, cipher=RC4-MD5, bits=128/128 Jul 29 23:46:11 one2action sendmail[2865]: STARTTLS=server, cert-subject=, cert-issuer=, verifymsg=ok Jul 29 23:46:11 one2action sendmail[2865]: AUTH: available mech=CRAM-MD5 DIGEST-MD5 LOGIN GSSAPI PLAIN, allowed mech=LOGIN PLAIN Jul 29 23:46:11 one2action sendmail[2865]: p6TMkB95002865: --- 220 one2action.com ESMTP Sendmail 8.14.4/8.14.4; Fri, 29 Jul 2011 23:46:11 +0100 Jul 29 23:46:11 one2action sendmail[2865]: STARTTLS=read, info: fds=8/4, err=2 Jul 29 23:46:12 one2action sendmail[2865]: p6TMkB95002865: <-- EHLO astronaut Jul 29 23:46:12 one2action sendmail[2865]: p6TMkB95002865: --- 250-one2action.com Hello 136-31-132-95.pool.ukrtel.net [95.132.31.136], pleased to meet you Jul 29 23:46:12 one2action sendmail[2865]: p6TMkB95002865: --- 250-ENHANCEDSTATUSCODES Jul 29 23:46:12 one2action sendmail[2865]: p6TMkB95002865: --- 250-PIPELINING Jul 29 23:46:12 one2action sendmail[2865]: p6TMkB95002865: --- 250-8BITMIME Jul 29 23:46:12 one2action sendmail[2865]: p6TMkB95002865: --- 250-SIZE Jul 29 23:46:12 one2action sendmail[2865]: p6TMkB95002865: --- 250-DSN Jul 29 23:46:12 one2action sendmail[2865]: p6TMkB95002865: --- 250-ETRN Jul 29 23:46:12 one2action sendmail[2865]: p6TMkB95002865: --- 250-AUTH LOGIN PLAIN Jul 29 23:46:12 one2action sendmail[2865]: p6TMkB95002865: --- 250-DELIVERBY Jul 29 23:46:12 one2action sendmail[2865]: p6TMkB95002865: --- 250 HELP Jul 29 23:46:12 one2action sendmail[2865]: STARTTLS=read, info: fds=8/4, err=2 Jul 29 23:46:12 one2action sendmail[2865]: p6TMkB95002865: <-- AUTH LOGIN Jul 29 23:46:12 one2action sendmail[2865]: p6TMkB95002865: --- 334 VXNlcm5hbWU6 Jul 29 23:46:12 one2action sendmail[2865]: STARTTLS=read, info: fds=8/4, err=2 Jul 29 23:46:12 one2action sendmail[2865]: p6TMkB95002865: --- 334 UGFzc3dvcmQ6 Jul 29 23:46:12 one2action sendmail[2865]: STARTTLS=read, info: fds=8/4, err=2 Jul 29 23:46:12 one2action sendmail[2865]: p6TMkB95002865: --- 535 5.7.0 authentication failed Jul 29 23:46:12 one2action sendmail[2865]: p6TMkB95002865: AUTH failure (LOGIN): generic failure (-1) SASL(-1): generic failure: checkpass failed, relay=136-31-132-95.pool.ukrtel.net [95.132.31.136] Jul 29 23:46:12 one2action sendmail[2865]: STARTTLS=read, info: fds=8/4, err=2 Jul 29 23:46:12 one2action sendmail[2865]: p6TMkB95002865: --- 421 4.4.1 one2action.com Lost input channel from 136-31-132-95.pool.ukrtel.net [95.132.31.136] Jul 29 23:46:12 one2action sendmail[2865]: p6TMkB95002865: lost input channel from 136-31-132-95.pool.ukrtel.net [95.132.31.136] to TLSMTA after auth Jul 29 23:46:12 one2action sendmail[2865]: p6TMkB95002865: 136-31-132-95.pool.ukrtel.net [95.132.31.136] did not issue MAIL/EXPN/VRFY/ETRN during connection to TLSMTA Here's dovecot -n # dovecot -n # 2.0.beta6 (3156315704ef): /etc/dovecot/dovecot.conf # OS: Linux 2.6.39.1-linode34 i686 CentOS Linux release 6.0 (Final) auth_cache_negative_ttl = 3600 s auth_debug_passwords = yes auth_mechanisms = plain login DIGEST-MD5 cram-md5 auth_worker_max_count = 3 default_client_limit = 10 default_process_limit = 5 disable_plaintext_auth = no listen = * log_path = /var/log/dovecot.log mail_location = mbox:~/mail:INBOX=/var/mail/%u mail_privileged_group = mail mbox_write_locks = fcntl passdb { args = scheme=MD5-CRYPT username_format=%u /etc/dovecot/dovecot.passwd driver = passwd-file } passdb { args = dovecot driver = pam } passdb { args = /etc/passwd driver = passwd-file } protocols = imap pop3 service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-userdb { group = smmsp mode = 0666 user = smmsp } unix_listener dovecot-auth { group = smmsp mode = 0666 user = smmsp } } service imap-login { inet_listener imaps { port = 993 ssl = yes } } service pop3-login { inet_listener pop3s { port = 995 ssl = yes } } ssl_cert = </etc/pki/tls/certs/sendmail.pem ssl_cipher_list = TLSv1+HIGH:!SSLv2:RC4+MEDIUM:!aNULL:!eNULL:!3DES:@STRENGTH ssl_key = </etc/pki/tls/certs/sendmail.pem userdb { args = username_format=%u /etc/dovecot/dovecot.passwd driver = passwd-file } protocol lda { auth_socket_path = /var/run/dovecot/auth-master postmaster_address = postmaster(a)example.com } protocol imap { imap_client_workarounds = delay-newmail } protocol pop3 { pop3_client_workarounds = outlook-no-nuls oe-ns-eoh pop3_uidl_format = %08Xu%08Xv } As I understand Sendmail now can't find Dovecot authentication via userdb and that's why a client isn't authenticated. Please help.

[Dovecot] lda_mailbox_autosubscribe - v2 wiki is a bit unclear
by Thomas Harold 29 Jul '11

29 Jul '11

In the old wiki: http://wiki1.dovecot.org/LDA -m <mailbox>: Destination mailbox (default is INBOX). If the mailbox doesn't exist, it's created (unless -n is used). If message couldn't be saved to the mailbox for any reason, it's delivered to INBOX instead. -s: Subscribe to mailboxes that are automatically created (via -m parameter or fileinto Sieve action). (v1.1.3+) Those have been replaced in Dovecot v2 with: # Should saving a mail to a nonexistent mailbox automatically create it? lda_mailbox_autocreate = no # Should automatically created mailboxes be also automatically subscribed? lda_mailbox_autosubscribe = no But neither of those options are mentioned on the LDA wiki page: http://wiki2.dovecot.org/LDA It's only mentioned in passing on the 2.0 page that explains the changes between 1.2 and 2.0.

[Dovecot] vpopmail + dovecot-lda doubling deliver messages
by Juliano Nascimento 29 Jul '11

29 Jul '11

We use qmail + vpopmail + dovecot, limits and alias are in vpopmail mysql database, it has worked ok. The .qmail-default: | /data/vpopmail/bin/vdelivermail '' bounce-no-mailbox | /var/qmail/bin/preline -f /usr/local/dovecot/libexec/dovecot/deliver -d $EXT@$USER When you send a message to alias works OK. The problem that is happening that is sent to asdf(a)domain.com asdf(a)domain.com he is doubling the email. Come the email that you sent / wrote an email and more with nearly no head, no matter. Searching is very realized that something related to Deliver the dovecot. Can you help us? Tips? Thank you all.

[Dovecot] vpopmail and proxy-* parameters (again)

Hello, I'm using a patched version of passdb-vpopmail.c to use CRAM-MD5 on the director. Today I updated the patch to 2.0.13. It may be an edge-case but I think it could be useful for somebody else. Greetings Martin

[Dovecot] want only usder in userfile/passfile and use to login user@domain
by Erik - versatel 28 Jul '11

28 Jul '11

After adding: auth_username_format=%Lu the %d domain is unfolleded correctly. (and not empty anymore) Maybe a good idee to make a remark in the text Virtual Users about that. I use: passdb: driver: passwd-file args: /etc/dovecot/vhosts/%d/etc/shadow userdb: driver: static args: uid=virtual gid=virtual home=/var/mail/vhosts/%d/%u In the password-file (shadow) i have to add users in the form user@domain. I want to add users in the form user I have also tryed not a static userdb but a real one; see example Dynamic-passwd locations. To get this working i had to add mail-uid and mail-gid. But still it has the same form user@domain and not user Can anybody tell my how to get ride of the domain part in the passwd en userfile. I still want the user to login with user@domain Thanks.

Hi, I upgrade my server an I have dovecot 2.0.9 (on RedHat 6) and my user uses Thunderbird 5.0 (on Windows XP). I use authentication via LDAP (Windows server 2003 AD). When users use in password diacritic marks (ą,ć,ę,ł,ń,ó) authentication failed. For example when user test have password: Sierpieńłą*123 in log file item appears: localhost dovecot: auth: ldap(test,192.168.0.68): invalid credentials (given password : SierpieDB#005*123) What can I do? Thanks

[Dovecot] dovecot quota feature request
by Shing 28 Jul '11

28 Jul '11

Hi all, I'm going to implement before queue quota check with postfix to prevent bounce mail, the quota information is stored into mysql using dovecot quotadict, it would be nice that dovecot can have an option to switch the quota check with (used space < quota) instead of (used space+mail size < quota), so that i can write a simple sql statement to check_recipient_access to reject those mail, thanks.
