Unexpected config results with local_name + multiple SSL certs
by David Favor 10 Mar '18

10 Mar '18

Working with SSL on fresh install of latest Ubuntu Artful + Dovecot seems broken somehow. Application is Dovecot listening for many SSL sites... Likely I've missed adding something simple to the config, related to local_name usage. Be great if someone can point out what I've missed, to setup multiple SSL certs for different host.domain entries in config. Thanks. _______ This works as expected... where the SNI server name is returned... #local_name imap.cydec.com { ssl_cert = </etc/letsencrypt/live/imap.cydec.com/fullchain.pem ssl_key = </etc/letsencrypt/live/imap.cydec.com/privkey.pem #} service dovecot restart && echo QUIT | openssl s_client -connect imap.cydec.com:993 -servername imap.cydec.com 2>&1 | egrep ^subject subject=/CN=imap.cydec.com _______ This fails... local_name imap.cydec.com { ssl_cert = </etc/letsencrypt/live/imap.cydec.com/fullchain.pem ssl_key = </etc/letsencrypt/live/imap.cydec.com/privkey.pem } service dovecot restart && echo QUIT | openssl s_client -connect imap.cydec.com:993 -servername imap.cydec.com 2>&1 | egrep ^subject # Empty, so no servername match _______ Full openssl output shows no cert being returned... service dovecot restart && echo QUIT | openssl s_client -connect imap.cydec.com:993 -servername imap.cydec.com CONNECTED(00000004) write:errno=104 --- no peer certificate available --- No client certificate CA names sent --- SSL handshake has read 0 bytes and written 199 bytes Verification: OK --- New, (NONE), Cipher is (NONE) Secure Renegotiation IS NOT supported Compression: NONE Expansion: NONE No ALPN negotiated SSL-Session: Protocol : TLSv1.2 Cipher : 0000 Session-ID: Session-ID-ctx: Master-Key: PSK identity: None PSK identity hint: None SRP username: None Start Time: 1519576210 Timeout : 7200 (sec) Verify return code: 0 (ok) Extended master secret: no --- _______ Config seems correct, with local_name uncommented... dovecot -n # 2.2.27 (c0f36b0): /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.16 (fed8554) # OS: Linux 4.13.0-36-generic x86_64 Ubuntu 17.10 auth_debug = yes auth_debug_passwords = yes auth_verbose = yes debug_log_path = /var/log/dovecot.log disable_plaintext_auth = no info_log_path = /var/log/dovecot.log log_path = /var/log/dovecot.log mail_debug = yes mail_location = mbox:~/mail:INBOX=/var/mail/%u namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { args = dovecot driver = pam } protocols = " imap pop3" service imap-login { inet_listener imap { port = 0 } inet_listener imaps { port = 993 ssl = yes } } service pop3-login { inet_listener pop3 { port = 0 } inet_listener pop3s { port = 995 ssl = yes } } userdb { driver = passwd } local_name imap.cydec.com { ssl_cert = </etc/letsencrypt/live/imap.cydec.com/fullchain.pem ssl_key = # hidden, use -P to show it }

mail_attachment_detection_options not working
by Alessio Cecchi 09 Mar '18

09 Mar '18

Hi, I enabled mail_attachment_detection_options on dovecot 2.2.34, in 10-mail.conf I have: mail_attachment_detection_options = add-flags-on-save but when an email is delivered in mailbox (Maildir) via LMTP no flag (HasNoAttachment or HasAttachment) was added. In dovecot-keywords file I have: 0 $HasNoAttachment 1 NonJunk 2 $HasAttachment so I thinks that the feature was eanbled but is unable. What am I doing wrong? Thanks -- Alessio Cecchi Postmaster @ http://www.qboxmail.it https://www.linkedin.com/in/alessice

Dovecot LMTP rejects all users as non-existent
by Alexander Harm 09 Mar '18

09 Mar '18

I'm running Dovecot 2.2.27 (c0f36b0) on Debian Stretch and I'm having some trouble with LMTP delivery from Postfix to Dovecot. The message in the logs is Mar 9 09:21:19 mail postfix/smtpd[3295]: NOQUEUE: reject: RCPT from some.mail.server[1.2.3.4]: 450 4.1.1 <alias(a)my.domain>: Recipient address rejected: unverified address: host my.mail.server[private/dovecot-lmtp] said: 550 5.1.1 <user(a)my.domain> User doesn't exist: user(a)my.domain (in reply to RCPT TO command); from=<someone(a)another.domain> to=<alias(a)my.domain> proto=ESMTP helo=<some.mail.server> However, testing my installation with doveadm works fine: doveadm user -u user(a)my.domain userdb: user(a)my.domain user : user(a)my.domain uid : 5000 gid : 5000 home : /srv/mail/vhosts/my.domain/user doveadm auth test user(a)my.domain passdb: user(a)my.domain auth succeeded I'm using a static userdb and a ldap passdb: # /etc/dovecot/conf.d/auth-ldap.conf.ext passdb { driver = ldap args = /etc/dovecot/dovecot-ldap.conf.ext } userdb { driver = static args = uid=vmail gid=vmail home=/srv/mail/vhosts/%d/%n } And my LDAP config reads like this # /etc/dovecot/dovecot-ldap.conf.ext uris = ldap://127.0.0.1 dn = uid=dovecot,ou=services,dc=my,dc=domain dnpass = ********* auth_bind = yes auth_bind_userdn = cn=%u,ou=mail,dc=my,dc=domain ldap_version = 3 base = ou=mail,dc=querco,dc=org deref = never scope = onelevel user_attrs = user_filter = (&(objectclass=PostfixBookMailAccount)(mailEnabled=TRUE)(cn=%u)) pass_attrs = cn=user,userPassword=password pass_filter = (&(objectclass=PostfixBookMailAccount)(mailEnabled=TRUE)(cn=%u)) iterate_attrs = cn=user iterate_filter = (&(objectclass=PostfixBookMailAccount)(mailEnabled=TRUE)) Sending the mail straight to user(a)my.domain works. Sending it to another alias works as well. Is there some caching problem and if so how to delete the cache (reboot didn't work)? Any pointers are highly appreciated.

Sieve filter doesn't respect mailbox separator
by Konstantinos Tsakiltzidis 09 Mar '18

namespace separator is '.', this sieve script incorrectly tries to put the mail inside a mailbox rather that beside it, for example if the mailbox is named 'example', the mail will be put in the path 'example/.Spam' instead of 'example.Spam' require ["fileinto"]; if header :contains "X-Spam" "yes" { fileinto "Spam"; } # 2.2.33.2 (d6601f4ec): /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.21 (92477967) # OS: Linux 4.9.0-6-amd64 x86_64 Debian 9.1 ext4 lda_mailbox_autocreate = yes lda_mailbox_autosubscribe = yes mail_debug = yes mail_location = maildir:/var/vmail/%d/%n 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 index ihave duplicate mime foreverypart extracttext namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = separator = . subscriptions = yes type = private } namespace modulus { list = children location = maildir:/var/vmail/%d/Public:INDEXPVT=~/public/indexes mailbox admin { auto = subscribe } mailbox support { auto = subscribe } mailbox telecoms { auto = subscribe } prefix = Public. separator = . subscriptions = yes type = public } passdb { driver = pam } plugin { acl = vfile mail_log_events = flag_change mail_log_fields = box flags uid sieve = ~/dovecot.sieve sieve_before = /var/vmail/global.sieve sieve_dir = ~/sieve sieve_global_dir = /var/vmail/sieve } protocols = " imap lmtp sieve lmtp" service auth { unix_listener /var/spool/postfix/private/auth { group = mail mode = 0666 user = postfix } unix_listener auth-userdb { group = mail mode = 0666 user = vmail } } 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 managesieve-login { inet_listener sieve { port = 4190 } process_min_avail = 0 service_count = 1 vsz_limit = 64 M } service managesieve { process_limit = 1024 } ssl = required ssl_cert = </etc/ssl/certs/mail.crt ssl_key = # hidden, use -P to show it userdb { driver = passwd } protocol imap { mail_max_userip_connections = 20 mail_plugins = " mail_log notify acl" passdb { args = /etc/dovecot/dovecot-ldap-users.conf.ext driver = ldap name = } userdb { args = uid=vmail gid=mail home=/var/vmail/%d/%n driver = static name = } } protocol lda { mail_plugins = " sieve acl" userdb { args = /etc/dovecot/dovecot-ldap-users.conf.ext driver = ldap name = override_fields = uid=vmail gid=mail home=/var/vmail/%d/%n } userdb { args = /etc/dovecot/dovecot-ldap-groups.conf.ext driver = ldap name = override_fields = uid=vmail gid=mail home=/var/vmail/%d/Public/.%n mail=maildir:/var/vmail/%d/Public/.%n } } protocol lmtp { mail_plugins = " sieve acl" postmaster_address = postmaster(a)modulus.gr userdb { args = /etc/dovecot/dovecot-ldap-users.conf.ext driver = ldap name = override_fields = uid=vmail gid=mail home=/var/vmail/%d/%n } userdb { args = /etc/dovecot/dovecot-ldap-groups.conf.ext driver = ldap name = override_fields = uid=vmail gid=mail home=/var/vmail/%d/Public/.%n mail=maildir:/var/vmail/%d/Public/.%n } } protocol doveadm { userdb { args = /etc/dovecot/dovecot-ldap-users.conf.ext driver = ldap name = override_fields = uid=vmail gid=mail home=/var/vmail/%d/%n } userdb { args = /etc/dovecot/dovecot-ldap-groups.conf.ext driver = ldap name = override_fields = uid=vmail gid=mail home=/var/vmail/%d/Public/.%n mail=maildir:/var/vmail/%d/Public/.%n } } protocol sieve { mail_max_userip_connections = 10 managesieve_implementation_string = Dovecot Pigeonhole managesieve_logout_format = bytes=%i/%o managesieve_max_line_length = 65536 passdb { args = /etc/dovecot/dovecot-ldap-users.conf.ext driver = ldap name = } userdb { args = uid=vmail gid=mail home=/var/vmail/%d/%n driver = static name = } }

Authentication Problem with dovecot-2.3.0.1
by Odhiambo Washington 08 Mar '18

08 Mar '18

I am a little confused here. I have been running 2.2.34 which I installed in /opt/dovecot2.2 I installed 2.3.0.1 to /opt/dovecot23 I then used config files from /opt/dovecot2.2/etc/dovecot to /opt/dovecot2.3/etc/dovecot and all I did was sed -i.BAK 's/dovecot2.2/dovecot2.3/g'. Dovecot started and was running file. Next, I manually crafted config files for 2.3.0.1 based on the example config files provided which diff-ing those with what I had for 2.2.34. I doub't if I missed something crucial during the process. 1. I realized that I cannot start 2.3.0.1 when I enable submission, since my Exim MTA is already using that port. This persists even if I tell the submission protocol to use a different port than 587. I tested 2587, but it would appear that 587 is hard-coded! 2. I realize that "unix_listener auth-client" service ceased to exist! 3. *I realized that while 2.2.34 runs with default_pass_scheme = MD5-CRYPT, 2.3.0.1 would not run with it.* 4. I have run dovecot -n from my 2.2.x installation and 2.3.x installation and here is the diff from the two files. I am confused why authentication is failing with dovecot-2.3.0.1 when it uses 2.3.x config files using MD5-CRYPT scheme while it is succeeding with dovecot-2.2.34 using the same. *Mar 07 22:30:22 auth: Info: sql(user.name(a)domain.name <user.name(a)domain.name>,192.168.55.97,<4CETl9dmscvAqDdh>): Requested DIGEST-MD5 scheme, but we have only MD5-CRYPT* Maybe the problem is elsewhere???

last login tracking

Hello, I've got dovecot going with postfix and MySQL database for user and domain storage. Dovecot handles the authentication. My last login is not working, does anyone have a table example and configs? I looked at the wiki page on the lastlogin plugin but obviously what I'm doing isn't working, I keep getting message write was unsuccessful for the lastlogin ip. I'd appreciate any help. Thanks.

Authentification fails in dovecot 2.3.0.1

Hi I've upgraded dovecot from 2.2.22 to 2.3.0.1. Now I can't authenticate any longer. My mail client says that the user name and password are rejected by dovecot. I get this line in /var/log/auth.log: Mar 6 19:28:02 desktop auth: PAM audit_log_acct_message() failed: Operation not permitted And this in /var/log/dovecot.log: Mar 06 19:28:02 auth: Debug: Loading modules from directory: /usr/lib/dovecot/modules/auth Mar 06 19:28:02 auth: Debug: Module loaded: /usr/lib/dovecot/modules/auth/lib20_auth_var_expand_crypt.so Mar 06 19:28:02 auth: Debug: Module loaded: /usr/lib/dovecot/modules/auth/libdriver_sqlite.so Mar 06 19:28:02 auth: Debug: Read auth token secret from /var/run/dovecot/auth-token-secret.dat Mar 06 19:28:02 auth: Debug: auth client connected (pid=5615) Mar 06 19:28:02 auth: Debug: client in: AUTH 1 PLAIN service=imap secured session=ggZPmsJmIoh/AAAB lip=127.0.0.1 rip=127.0.0.1 lport=993 rport=34850 local_ Mar 06 19:28:02 auth-worker(5617): Debug: Loading modules from directory: /usr/lib/dovecot/modules/auth Mar 06 19:28:02 auth-worker(5617): Debug: Module loaded: /usr/lib/dovecot/modules/auth/lib20_auth_var_expand_crypt.so Mar 06 19:28:02 auth-worker(5617): Debug: Module loaded: /usr/lib/dovecot/modules/auth/libdriver_sqlite.so Mar 06 19:28:02 auth-worker(5617): Debug: pam(v,127.0.0.1,<ggZPmsJmIoh/AAAB>): lookup service=dovecot Mar 06 19:28:02 auth-worker(5617): Debug: pam(v,127.0.0.1,<ggZPmsJmIoh/AAAB>): #1/1 style=1 msg=Password: Mar 06 19:28:02 auth-worker(5617): Info: pam(v,127.0.0.1,<ggZPmsJmIoh/AAAB>): pam_authenticate() failed: System error Mar 06 19:28:04 auth: Debug: client passdb out: FAIL 1 user=v Mar 06 19:28:06 imap-login: Info: Aborted login (auth failed, 1 attempts in 4 secs): user=<v>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, TLS, session=<ggZPmsJmIoh/AAAB> Now it seems I can't go back to 2.2.22 as well: https://wiki2.dovecot.org/Upgrading/2.3 says "Downgrading is possible to v2.2.27 and later.

AppArmor profile for Dovecot on Debian Stretch
by André Rodier 08 Mar '18

08 Mar '18

Hello all, Is there any guide to help in the configuration of Dovecot for AppArmor on Debian / Ubuntu ? Or maybe does any of you already have something that works? I am actually adding AppArmor on an email server project, and I had some trouble with the versions from Debian. I would like to avoid - if possible - the long try and error process for each Dovecot executable. I am using IMAP, LMTP, Sieve and ManageSieve, with LDAP users. The full project reference is here: https://github.com/progmaticltd/homebox ii dovecot-core 1:2.2.27-3+deb9u2 amd64 ii dovecot-imapd 1:2.2.27-3+deb9u2 amd64 ii dovecot-ldap 1:2.2.27-3+deb9u2 amd64 ii dovecot-lmtpd 1:2.2.27-3+deb9u2 amd64 ii dovecot-managesieved 1:2.2.27-3+deb9u2 amd64 ii dovecot-pop3d 1:2.2.27-3+deb9u2 amd64 ii dovecot-sieve 1:2.2.27-3+deb9u2 amd64 Thanks for your advices André
