Should dovecot not be using different severity levels like auth.warn?

ACL ignored for master users
by Philip Iezzi 14 Aug '19

14 Aug '19

Hi there! I can't get ACL working for master users. Login as master user works fine though, and I am able to access any mailbox using the auth_master_user_separator "*", tested e.g. via Python's imaplib: import imaplib imap = imaplib.IMAP4_SSL('imap.example.com') imap.login('foo(a)example.com*admin-acldemo', '**********') ('OK', [b'Logged in']) My /etc/dovecot/dovecot-acl looks like this: * user=admin lr bar(a)example.com user=admin-acldemo lr So, if I didn't misunderstand https://wiki.dovecot.org/Authentication/MasterUsers and https://wiki.dovecot.org/ACL documentation, this should only give "admin" master user access to all mailaccounts and limiting "admin-acldemo" master user to only a single mailaccount. That's what I would like to accomplish. But no matter what I put into dovecot-acl (it could even be empty), master users always have access to all existing mailaccounts. The whole dovecot-acl seems to be ignored and there are no logs pointing to any problem (syntax, access permissions) with that file. In mail.log I am getting a successful login message: dovecot: imap-login: Login: user=<foo(a)example.com>, method=PLAIN, ... So the login with "foo(a)example.com*admin-acldemo" seems to get resolved to a regular "foo(a)example.com" user login. My current setup (relevant config options): # 2.3.7.1 (0152c8b10): /etc/dovecot/dovecot.conf # Pigeonhole version 0.5.7.1 (db5c74be) # OS: Linux 4.15.18-18-pve x86_64 Debian 9.9 auth_master_user_separator = * mail_plugins = quota acl passdb { args = /etc/dovecot/passwd.masterusers driver = passwd-file master = yes pass = yes } plugin { acl = vfile:/etc/dovecot/dovecot-acl acl_user = %u master_user = %u } protocol lmtp { mail_plugins = quota acl sieve } protocol lda { mail_plugins = quota acl sieve } protocol imap { mail_plugins = quota acl imap_acl imap_quota } On ACL documentation it says: > Note that master users have their own ACLs. They're not the the mailbox owners, so by default they have no permissions to any of the mailboxes and on Authentication/MasterUsers documentation: > If ACL plugin is enabled, the Master user is still subject to ACLs just like any other user, which means that by default the master user has no access to any mailboxes of the user. So it must be somehow possible to limit master users to specific mailbox(es) via ACL. I could allow master users to be able to log in as themselves, by adding two passdb sections (one with `master = yes`, the other `master = no`), but then I see no way to do a user context switch (where ACLs would get respected...) after logging in with "admin". Any help greatly appreciated! Thanks in advance. Cheers, Philip

Dovecot - Microsoft Azure AD
by Lennart Boettcher 14 Aug '19

14 Aug '19

Hello, I am currently trying to connect my Dovecot mail server to Microsoft's Azure-AD and use it as password and user database. I am using version 2.3.7.1. Using the Azure-AD as passdb already works. In this context I noticed that the scope implementation is not yet merged. Since I haven't found any hints for an OAuth2 userdb implementation yet, I wanted to ask if there are any plans for an implementation. Greetings Lennart Boettcher

Solr, Dovecot & macOS / iOS
by James Brown 14 Aug '19

14 Aug '19

I’m thinking of getting Solr working with my Dovecot server. Server is new 6-core Mac Mini, mail store of over 1/2 TB. Mailboxes with 100s of thousands of messages. But I’m not sure if: a) it will make enough of a difference and b) does Mail.app and other mail clients on Macs or iOS devices perform searches on their local copy of mail or does it just send a search request to the server? I’m guessing the searches are done locally so no point in Solr? Does anyone know? Thanks, James.

Dovecot Sieve doesn't move spam to Junk folder in maildir
by Nagy Tibor 13 Aug '19

13 Aug '19

I have an *Ubuntu 16.04* mail server with postfix/spamassassin/*dovecot-2.2.2**2* with virtual mailboxes in maildir format. The whole process is working excellently since a year. Spams are marked with "*****SPAM*****" in subject and with "X-Spam-Flag: YES" in email header. I tried now to add sieve to dovecot to move the SPAM messages into the Junk folder without any success, I don't see any sign that sieve does something at all.

dovecot-lmtp and postfix
by Coy Hile 12 Aug '19

12 Aug '19

Hi all, I’ve got postfix setup to use dovecot-lmtp for (virtual) user delivery, and things to users or aliases that Dovecot knows about now get delivered correctly. However, I’ve done something wrong with postfix and/or the LMTP configuration because upon RCPT TO, instead of forwarding the mail off to the configured smartest, somehow dovecot-lmtp is ending up in the mix. (Perhaps this is more a postfix question than a dovecot one, but, I’ll start here.) Relevant postfix config: [root@81716ec5-bca4-6d53-ed81-bd1a55d46b4f /opt/local/etc/postfix]# postconf -n canonical_maps = hash:/opt/local/etc/postfix/canonical command_directory = /opt/local/sbin compatibility_level = 2 daemon_directory = /opt/local/libexec/postfix data_directory = /var/db/postfix debug_peer_level = 2 debugger_command = PATH=/bin:/usr/bin:/usr/local/bin:/usr/X11R6/bin ddd $daemon_directory/$process_name $process_id & sleep 5 default_database_type = hash home_mailbox = Maildir/ html_directory = no inet_interfaces = all inet_protocols = all mail_owner = postfix mailbox_size_limit = 102400000 mailq_path = /opt/local/bin/mailq manpage_directory = /opt/local/man message_size_limit = 51200000 meta_directory = /opt/local/libexec/postfix mynetworks = $myhostname, 127.0.0.0/8, 10.0.0.0/8, 172.16.0.0/12 192.168.0.0/16 newaliases_path = /opt/local/bin/newaliases owner_request_special = no queue_directory = /var/spool/postfix queue_minfree = 76800000 readme_directory = /opt/local/share/doc/postfix recipient_canonical_maps = hash:/opt/local/etc/postfix/recipient_canonical recipient_delimiter = + relayhost = relay.svc.a4b01392-e48d-4cdf-cacf-f850d1800d45.basement.cns.coyhile.com sample_directory = /opt/local/share/examples/postfix sender_canonical_maps = hash:/opt/local/etc/postfix/sender_canonical sendmail_path = /opt/local/sbin/sendmail setgid_group = maildrop shlib_directory = /opt/local/lib/postfix smtpd_banner = $myhostname ESMTP smtpd_client_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unknown_reverse_client_hostname smtpd_data_restrictions = permit_mynetworks, reject_unauth_pipelining, permit_sasl_authenticated smtpd_helo_required = yes smtpd_helo_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_invalid_helo_hostname, reject_non_fqdn_helo_hostname smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unlisted_recipient, reject_non_fqdn_recipient, reject_unauth_destination, reject_unknown_recipient_domain, check_recipient_access hash:/opt/local/etc/postfix/filtered_domains smtpd_sasl_auth_enable = yes smtpd_sasl_path = private/auth smtpd_sasl_type = dovecot smtpd_sender_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unlisted_sender, reject_non_fqdn_sender, reject_unknown_sender_domain smtputf8_enable = no strict_rfc821_envelopes = yes unknown_local_recipient_reject_code = 550 virtual_alias_maps = pgsql:/opt/local/etc/postfix/postfix_virtual_aliases.cf virtual_mailbox_domains = pgsql:/opt/local/etc/postfix/postfix_virtual_domains.cf virtual_transport = lmtp:unix:private/dovecot-lmtp [root@81716ec5-bca4-6d53-ed81-bd1a55d46b4f /opt/local/etc/postfix]# And the dovecot config: doveconf -n #

Gmail to Dovecot migration
by Yuri 12 Aug '19

12 Aug '19

Hi everyone, I'm trying to migrate my gmail to dovecot following instructions at https://wiki.dovecot.org/Migration/Gmail Using -a 'virtual/All' option does not seem to work because the gmail folder with that name does not exist, but -a '[Gmail]/All Mail' seem to work. I'm using the following command: sudo doveadm \ -o imapc_host=imap.gmail.com \ -o imapc_user=user(a)gmail.com \ -o imapc_password=gmailpassword \ -o imapc_features="rfc822.size gmail-migration" \ -o imapc_port=993 \ -o imapc_ssl=imaps \ -o ssl_client_ca_dir=/etc/ssl/certs \ -o imapc_ssl_verify=yes \ backup -a '[Gmail]/All Mail' -O '-$GmailHaveLabels' -R -u user(a)exmaple.com imapc: The problem is this command only migrates approximately 25% of my emails by size. Google Takeout exports 4 times more data in mbox format, the size of exported mboxes aligns with what Google tells me a the bottom of gmail settings page. I experimented with other options of 'doveadm backup' command, but they all resulted in less data being migrated. The above options are the best I was able to achive so far. Another option I was considering is to convert Google Takeout mboxes to dovecot format. I tried using 'doveadm import' command, but got confused with various user and search query options of the command. The best I was able to achive was to output a folder under /Takeout which mimics my mbox structure, but with no imported messages. A third option I'm considering is to convert Google Takeout mboxes using mb2md command. Conversion seems to work fine, but the output is in the traditional (dotted) format, and for historical reasons I use 'LAYOUT=fs' option. So I need to do some extra work to convert folder names. And even if I do so, I'm still not sure if I can import Maildir to dovecot because dovecot's Maildir has other information, such as indices, logs, etc., not just email folders. I'll keep investigating the second and the third option because it seems that Google Takeout gives me all my emails, but I'm not sure if those are the right paths. I wanted to ask the experts about the best option to migrate gmail to dovecot. Has anyone being able to successfully migrate all their emails from gmail and what steps have been used for that? My Dovecot version: 2.3.4.1 Thank you, Yuri
