Your logics sucks. There is a difference between how email works and how spamassassin works. You are assuming that everyone in the world is using spamassassin by including it in 'how email works'. Maybe you like to post a link to your bayes files???? Am 11.06.20 um 11:13 schrieb Marc Roos: > You do not understand how mail works.

You do not understand how mail works. Google mail is only getting through when spf checks and the likes are being passed. I am not creating any problems with this, I am just bouncing them back. Google has enough billions to handle these issues. If everyone would apply this procedures, people with legitimate email accounts would move from a spam network to some other provider. People joining these providers are the problem, because it allows these networks to mix spam with legitimate email. When clients start moving out, spam networks are becoming easier to hard block and these providers start thinking about their infrastructure and their bussines model. If everyone would be doing this, it is solving the spam problem. My below procedure should be applicable for any network generating a lot of spam. -----Original Message----- From: Reindl Harald [mailto:h.reindl@thelounge.net] Sent: donderdag 11 juni 2020 10:25 To: Marc Roos; dovecot; users Subject: Re: handling spam from gmail.

How to unset namespace configuration from dovecot.conf in conf.d/99-cutom.conf?
by Py Retta 09 Jun '20

09 Jun '20

Dear all, my /etc/dovecot/dovecot.conf [0] that is shipped with the Linux distro (Ubuntu 18.04, dovecot 2.3.10) has a namespace section: namespace inbox { ... mailbox Sent { ... } ... } I need to remove this whole section from the configuration, but I need to do this in a file such as /etc/dovecot/conf.d/99-custom.conf because I want this modification to be stable against automatic updates of dovecot.conf shipped by the distro. This raises the question, how do I "unset" an earlier namespace configuration at a later point in the stack of config files? Speaking in terms of `doveconf -n`, snippet [1] below lists the original configuration (including namespace setup) and [2] lists the desired configuration that results from deleting the namespace passage from dovecot.conf. However, I would like to achieve it without deleting it from dovecot.conf but by adding sth to conf.d/99-custom.conf. Thanks a lot, Py [0] original dovecot.conf (only relevant namespace section): # Default private namespace setup compatible with Courier-IMAP. namespace inbox { separator = . prefix = INBOX. inbox = yes mailbox Sent { auto = subscribe # autocreate and autosubscribe the Sent mailbox special_use = \Sent } mailbox Spam { auto = create # autocreate Spam, but don't autosubscribe special_use = \Junk } mailbox Drafts { auto = create special_use = \Drafts } mailbox Trash { auto = create special_use = \Trash } } [1] `doveconf -n` for the original configuration: # 2.3.10 (0da0eff44): /etc/dovecot/dovecot.conf # Pigeonhole version 0.5.9 (db4e9a2f) doveconf: Warning: service auth { client_limit=1000 } is lower than required under max. load (2248) doveconf: Warning: service anvil { client_limit=1000 } is lower than required under max. load (2251) # OS: Linux 4.15.0 x86_64 Ubuntu 18.04.4 LTS ext4 # Hostname: ############ auth_mechanisms = ####################### auth_username_chars = ################ disable_plaintext_auth = #### first_valid_uid = #### imap_client_workarounds = delay-newmail imap_logout_format = rcvd=%i, sent=%o mail_home = ################## mail_location = ##################### mail_log_prefix = "service=%s, user=%u, ip=[%r].

doveadm protocol bug
by Felipe Gasper 08 Jun '20

08 Jun '20

Hi everyone, On 26th May I emailed this list a few times about an apparent protocol bug in Dovecot’s server-side doveadm implementation. Later that day I sent in a pull request to fix the issue. Thread reference: https://dovecot.org/pipermail/dovecot/2020-May/119066.html Pull request: https://github.com/dovecot/core/pull/129 Thus far neither the mailing list emails nor the PR have garnered any responses. Can someone please weigh in on these? It’s totally understandable if Dovecot’s behavior here is going to say as-is; I’d just like some confirmation so we can note it in our client implementation. (Switching our client to the HTTP API would be out-of-scope for our current project.) Thank you again! cheers, -Felipe Gasper

Can't share a mailbox
by Maxime DERCHE 08 Jun '20

08 Jun '20

Hello, I have a "notifs@" generic mail account, intended to receive technical monitoring messages. I need to share it with the people of the analyst team. I created a shared namespace, and enabled the modules. doveadm acl creates the dovecot-acl file but not the acl_shared_dict file. I guess something prevents it from doing it, but I fail to see what. It is a LDAP setup, and there is only one vmail (uid/gid 500) UNIX account to read and write the files on the file system. $ > doveadm acl add -u notifs(a)test.example.tld "shared/notifs(a)test.example.tld/INBOX" user=maxime.derche(a)test.example.tld :lrw $ > doveadm acl debug -u maxime.derche(a)test.example.tld "shared/notifs(a)test.example.tld/INBOX" doveadm(maxime.derche(a)test.example.tld): Info: Mailbox 'INBOX' is in namespace 'shared/notifs(a)test.example.tld/' doveadm(maxime.derche(a)test.example.tld): Info: Mailbox path: /var/vmail/test.example.tld/notifs/mail doveadm(maxime.derche(a)test.example.tld): Info: Per-user private flags in mailbox: \Seen doveadm(maxime.derche(a)test.example.tld): Info: User maxime.derche(a)test.example.tld has rights: lrw doveadm(maxime.derche(a)test.example.tld): Error: User maxime.derche(a)test.example.tld is missing 'lookup' right doveadm(maxime.derche(a)test.example.tld): Info: Mailbox shared/notifs(a)test.example.tld/INBOX is NOT visible in LIST /var/vmail/test.example.tld/notifs/mail/dovecot-acl: ---------------------------------------- user=maxime.derche(a)test.example.tld :lrw ---------------------------------------- dovecot -n ---------------------------------------- # 2.3.4.1 (f79e8e7e4): /etc/dovecot/dovecot.conf # Pigeonhole version 0.5.4 () # OS: Linux 4.19.0-9-amd64 x86_64 Debian 10.4 # Hostname: server.example.tld auth_debug = yes auth_mechanisms = plain login auth_verbose = yes lda_mailbox_autocreate = yes lda_mailbox_autosubscribe = yes lmtp_save_to_detail_mailbox = yes mail_access_groups = vmail mail_debug = yes mail_gid = 5000 mail_location = maildir:~/Maildir mail_plugins = quota acl mail_privileged_group = mail mail_server_admin = mailto:postmaster@test.example.tld mail_shared_explicit_inbox = yes mail_uid = 5000 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 imapsieve vnd.dovecot.imapsieve namespace { list = children location = maildir:%%h/mail:INDEXPVT=~/mail/shared/%%u prefix = shared/%%u/ separator = / subscriptions = no type = shared } namespace inbox { inbox = yes location = mailbox Drafts { auto = subscribe special_use = \Drafts } mailbox Junk { auto = subscribe autoexpunge = 30 days special_use = \Junk } mailbox Sent { auto = subscribe special_use = \Sent } mailbox Trash { auto = subscribe autoexpunge = 30 days special_use = \Trash } prefix = separator = / } passdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { acl = vfile acl_shared_dict = file:/var/vmail/shared-mailboxes imapsieve_mailbox1_before = file:/etc/dovecot/sieve/learn-spam.sieve imapsieve_mailbox1_causes = COPY imapsieve_mailbox1_name = Junk imapsieve_mailbox2_before = file:/etc/dovecot/sieve/learn-ham.sieve imapsieve_mailbox2_causes = COPY imapsieve_mailbox2_from = Junk imapsieve_mailbox2_name = * recipient_delimiter = + sieve = file:~/sieve;active=~/.dovecot.sieve sieve_after = /etc/dovecot/sieve-after sieve_before = /etc/dovecot/sieve-before sieve_global_extensions = +vnd.dovecot.pipe sieve_pipe_bin_dir = /etc/dovecot/sieve sieve_plugins = sieve_imapsieve sieve_extprograms } protocols = " imap lmtp sieve" service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0600 user = postfix } } ssl = required ssl_cert = </etc/ssl/certs/cert.pem ssl_cipher_list = HIGH:!ADH:!AECDH:!PSK:!KRB5:!RC4:!DES:!3DES:!MD5 ssl_client_ca_dir = /etc/ssl/certs ssl_dh = # hidden, use -P to show it ssl_key = # hidden, use -P to show it ssl_min_protocol = TLSv1.2 ssl_prefer_server_ciphers = yes userdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap override_fields = home=/var/vmail/%d/%n } protocol lmtp { mail_plugins = quota acl sieve userdb { args = allow_all_users=yes uid=vmail gid=vmail home=/var/vmail/%d/%n mail=maildir:~/mail driver = static name = } } protocol imap { mail_plugins = quota acl imap_sieve imap_acl } ---------------------------------------- Does anyone see what I'm doing wrong here?

Doveadm Backup issues
by Francis Augusto Medeiros-Logeay 07 Jun '20

07 Jun '20

Hi, I'm trying to use doveadm backup but I'm having a few issues. When trying locally: `doveadm backup -D -A maildir:/usr/local/backup` It results that no mailbox is separated by user - all seems to sync on the same folder, messing up with the folder structure of the original maildir. When trying remotely: `doveadm backup -D -A -N ssh -i mykey root@myremotebackup.com:/backup doveadmin dsync-server -A` I get this error line for each user: dsync-local(theuser(a)thedomain.com)<5DNrEXdG1l5tAgAAqsACHw>: Error: read(remote) failed: EOF (version not received) doveadm(theuser(a)thedomain.com): Fatal: execvp(ssh) failed: No such file or directory I'd be very thankful if someone could help me with this. Best, Francis -- Francis Augusto Medeiros-Logeay Oslo, Norway

Deliver administrative message ignoring user quota
by Peter Folta 07 Jun '20

07 Jun '20

Hi everyone, I have a separate internal system running on a different host that needs to put an administrative email into a user’s inbox. I’ve been playing around with the “doveadm mailbox save” command via Doveadm’s HTTP API (https://doc.dovecot.org/admin_manual/doveadm_http_api/#doveadm-mailbox-save <https://doc.dovecot.org/admin_manual/doveadm_http_api/#doveadm-mailbox-save>). This works quite well provided the user is within quota limit, however, I would like to be able to deliver these messages even if the email account is over quota. I noticed that it’s possible to override the quota configuration using dovecot-lda by overriding plugin/quota with the “noenforcing” directive as explained in https://wiki.dovecot.org/Quota/Configuration <https://wiki.dovecot.org/Quota/Configuration>. I don’t currently use LDA, SMTP servers based on Postfix deliver mail via LMTP and I need to be able to deliver this message from a different host in the network. The HTTP API doesn’t seem to support overriding the quota config. What would be the best way to go about this? Thanks Peter

I want to disable the time penalty for dovecot imap authentication. When receiving a valid user-password combo the server responds in .04 seconds. When I send in an invalid comination it will either respond in 1.544 or 2.044 seconds += .002 I am using dovecot to test a program that sends a login request to a server and processes the response. I want to be able to send a series of valid and invalid login attempts. The issue is that with the 2 seconds delay for a bad login attempt, the tests are too slow to run in production I can see that the delay is defined in auth-penalty.h Is there a way, in the config file, to set AUTH_PENALTY_INIT_SECS = 0, or any other way to remove the time delay for an invalid login. I am running dovecot version 2.2.33.2 I am running without root permissions I do not want to make changes outside of the dovecot config file, password file, or run folder. -- Stephen

Cannot log in to IMAP server and logs are unclear as to why
by Scott A. Wozny 07 Jun '20

07 Jun '20

I’m trying a super basic config based upon https://wiki.dovecot.org/HowTo/PostfixDovecotLMTP but before I work on shipping mail through Postfix to DoveCot, I wanted to make sure IMAP is working first, but I can’t even get a basic login to so I thought I’d see if the gurus on the list might be able to point out I’m doing wrong. The documentation is pretty good, but there were some gaps I had to guess at and I’m presuming that’s where I went wrong. I’ve turned SELinux to permissive mode, for now. Here’s the doveconf -n: # 2.2.36 (1f10bfa63): /etc/dovecot/dovecot.conf # OS: Linux 3.10.0-1062.12.1.el7.x86_64 x86_64 CentOS Linux release 7.7.1908 (Core) # Hostname: imap first_valid_uid = 1000 listen = 192.168.1.207 mail_gid = vmail mail_home = /var/vmail/%d/%n mail_location = sdbox:~/mail mail_uid = vmail mbox_write_locks = fcntl 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 = / } passdb { args = scheme=PLAIN username_format=%u /etc/dovecot/users driver = passwd-file } protocols = imap lmtp service lmtp { group = vmail unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0600 user = postfix } user = vmail } ssl = no ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = # hidden, use -P to show it userdb { args = username_format=%u /etc/dovecot/users driver = passwd-file } I wasn’t sure how to set rights on the users file: [sawozny@imap var]$ cat /etc/dovecot/users test@test.com:{plain}test [sawozny@imap var]$ ls -la /etc/dovecot/users -rw-r--r--. 1 root root 26 Jun 3 23:31 /etc/dovecot/users Also, didn’t know what rights to set on the /var/vmail directoy so I did this: drwxrwx---. 3 vmail vmail 4096 Jun 3 20:52 vmail This directory is also empty except for the lost+fond directory that comes with a disk mount point. My understanding is that the mail home and maildir will manifest automagically on first login, but if I need to prime the pump, please let me know what I need to do. For my test, I did: [sawozny@imap var]$ telnet 192.168.1.207 143 Trying 192.168.1.207... Connected to 192.168.1.207.

From my understanding of the documentation, all I need in the userdb is name and password. UID, GID and HOME are also indicated as required, but I set them at the system level, so why is the system telling me the user was not found? This definitely isn’t my first rodeo with Linux, but I know almost nothing about messaging so in that regard I’m a totally n00b and would really appreciate some guidance. Thanks, Scott
