Which headers are you taking about? If you're talking about Received: headers, that's usually inserted by your MTA, not dovecot. Joseph Tam <jtam.home(a)gmail.com>

LMTP doing passdb queries ?
by Peter Mogensen 22 Aug '16

22 Aug '16

Hi, I can see dovecot is doing a passdb query when handling the LMTP RCPT command. That's kinda unexpected for me. I would have thought it only did a userdb lookup. I have disabled lmtp_proxy to be sure it didn't do a passdb lookup to check the proxy field. Is this expected? Doesn't the LDA only do userdb lookups? /Peter

Catch-all with LMTP and Postfix
by Michael Starks 22 Aug '16

22 Aug '16

Hidy-ho, I'm having a difficult time getting catch-all working when using Dovecot LMTP. I would like *(a)example.com (everything) to go to virtual(a)example.com, where virtual is a valid virtual user. It seems that things are getting as far as LMTP, but then the mail gets bounced. To wit: Aug 21 08:02:50 hostname postfix/lmtp[4914]: 8DF8E9AFE6: to=<test(a)example.com>, relay=mail.example.com[private/dovecot-lmtp], delay=0.07, delays=0.04/0.01/0.01/0.01, dsn=5.1.1, status=bounced (host mail.example.com[private/dovecot-lmtp] said: 550 5.1.1 <test(a)example.com> User doesn't exist: test(a)example.com (in reply to RCPT TO command)) In the previous log example, test(a)example.com should have been forwarded (aliased) to the virtual mail user.

Field Return-Path contains twice the domain
by Quaquaraquà 22 Aug '16

22 Aug '16

Dear exim & dovecot users, posting on both mailing lists as I am not sure who has the ultimate responsability for this field. I am trying to set up a mail server for multiple domains in my VPS. So I managed to set up the authentication through a dovecot authenticator, which relies to a sqlite database. I would like that, from the database perspective, a query has, as input parameters, both the username and the domain to check the password. For this purpose, I am requesting that the SMTP account is in the full form username(a)domain.com. When forwarded to the dovecot authenticator, I can extract the user with %n and %d. This works, but it has a utter drawback: emails are sent repeating twice the domain in the Return-Path field, e.g. : Return-Path: <"user(a)domain.net"@domain.net> Subject: Re: Hello To: nuquaquaraqua(a)gmail.com From: user <user(a)domain.net> How do I properly fix the field Return-Path now? dovecot --version: 2.2.25 (7be1766) Exim version 4.87 #1 built 28-Jul-2016 18:38:04 Kind regards, Quaquaraqua

Occasional error from TB when selecting a dovecot's shared mbox: "Unable to open the summary file for [shared]" "Perhaps there was an error on disk, or the full path is too long." The server's disk is clear, and the longest full path is [a-zA-Z\/\.]{46}. The error occurs occasionally.

What might cause messages delivered with dovecot-lda to be "invisible" to IMAP clients?
by Ben Johnson 19 Aug '16

19 Aug '16

Hello! I'm attempting to use dovecot-lda, and for whatever reason, messages that I send with it are not visible in my IMAP client. $ dovecot --version 2.2.22 (fe789d2) (Full "doveconf -n" output is at the bottom of this message!) Here's the the sequence of commands that I'm using: # su vmail $ echo 'This is a test message.' > /tmp/test.txt $ stat /tmp/test.txt File: '/tmp/test.txt' Size: 24 Blocks: 8 IO Block: 4096 regular file Device: fd01h/64769d Inode: 783925 Links: 2 Access: (0664/-rw-rw-r--) Uid: ( 5000/ vmail) Gid: ( 5000/ vmail) Access: 2016-08-18 20:49:38.419011552 -0400 Modify: 2016-08-18 20:49:07.178995015 -0400 Change: 2016-08-18 20:49:38.191011425 -0400 Birth: - $ /usr/lib/dovecot/dovecot-lda -d "test(a)example.com" -p "/tmp/test.txt" When I do this, the destination mailbox acts like there's a new message (I'm using Thunderbird, and the mailbox is highlighted in blue and bolded, which is the "new mail" behavior in this client). But when I "check my inbox", i.e., click on the Inbox, I don't see the new message. With regard to the filesystem, the message is present and contains the intended contents. Here's the "stat" output: $ stat /var/vmail/example.com/ben/Maildir/cur/1471567777.M685753P32257.example.com,S=24:2, File: '/var/vmail/example.com/ben/Maildir/cur/1471567777.M685753P32257.example.com,S=24:2,' Size: 24 Blocks: 8 IO Block: 4096 regular file Device: fd01h/64769d Inode: 783925 Links: 2 Access: (0664/-rw-rw-r--) Uid: ( 5000/ vmail) Gid: ( 5000/ vmail) Access: 2016-08-18 20:51:05.647059340 -0400 Modify: 2016-08-18 20:50:58.543055378 -0400 Change: 2016-08-18 20:50:58.543055378 -0400 Birth: - Might anyone know why I'm not "seeing" this message in my IMAP client? Interestingly, I tried another IMAP client (Blue Mail for Android), and I can actually see the messages there, but they appear in the Inbox as: (No subject) <Empty Message> When I click on the messages, Blue Mail simply displays "No text", without the quotes. Surely, I'm overlooking something simple... Thank you for any help here! -Ben Full "doveconf -n" output: $ doveconf -n # 2.2.22 (fe789d2): /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.13 (7b14904) # OS: Linux 4.4.0-34-generic x86_64 Ubuntu 16.04.1 LTS auth_mechanisms = plain login disable_plaintext_auth = no listen = *,[::] log_timestamp = "%Y-%m-%d %H:%M:%S " mail_max_userip_connections = 100 mail_plugins = " quota" mail_privileged_group = vmail passdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } plugin { antispam_backend = pipe antispam_debug_target = syslog antispam_pipe_program = /bin/bash antispam_pipe_program_args = /usr/local/bin/sa-learn-pipe.sh antispam_pipe_program_notspam_arg = --ham antispam_pipe_program_spam_arg = --spam antispam_pipe_tmpdir = /tmp antispam_spam_pattern_ignorecase = SPAM;JUNK antispam_trash_pattern_ignorecase = trash;Deleted * antispam_verbose_debug = 1 quota = dict:user::file:/var/vmail/%d/%n/.quotausage quota_rule2 = Trash:storage=+100M quota_rule3 = Junk:ignore quota_rule4 = INBOX:storage=+100M quota_warning = storage=100%% quota-reached 100 %u %d quota_warning2 = storage=95%% quota-warning 95 %u %d quota_warning3 = storage=80%% quota-warning 80 %u %d quota_warning4 = -storage=100%% quota-below below %u %d sieve = /var/vmail/%d/%n/.sieve sieve_max_redirects = 25 } postmaster_address = postmaster(a)example.com protocols = imap pop3 service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-userdb { group = vmail mode = 0600 user = vmail } user = root } service imap-login { client_limit = 1000 process_limit = 512 } service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0600 user = postfix } } service quota-below { executable = script /usr/local/bin/quota-below.sh unix_listener quota-below { group = vmail mode = 0666 user = vmail } user = vmail } service quota-reached { executable = script /usr/local/bin/quota-reached.sh unix_listener quota-reached { group = vmail mode = 0666 user = vmail } user = vmail } service quota-warning { executable = script /usr/local/bin/quota-warning.sh unix_listener quota-warning { group = vmail mode = 0666 user = vmail } user = vmail } ssl_cert = </etc/postfix/smtpd.cert ssl_key = </etc/postfix/smtpd.key ssl_protocols = !SSLv2 !SSLv3 userdb { driver = prefetch } userdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } protocol imap { mail_plugins = quota imap_quota antispam } protocol pop3 { mail_plugins = quota pop3_uidl_format = %08Xu%08Xv } protocol lda { mail_plugins = sieve quota } protocol lmtp { mail_plugins = quota sieve postmaster_address = webmaster@localhost }

Hello everyone, I face the following challenge: - dovecot 2.2.13 - userdb: passwd-file - quota enabled: -- default 1GB -- changed for some users thru users file: user@domain:passwd::::::userdb_quota_rule=*:storage=15M - when sending a message to this user while near quota, warnings are correctly triggered => *OK* - when sending a message to this user while over quota, message is refused => *OK* - when checking quota from mail client (eg Thunderbird 45.2), reported quota is.. 1GB => *NOK* - some config: mail_plugins = quota notify acl plugin { acl_shared_dict = file:/sd/MAIL_IMAP_POP/%d/shared-mailboxes quota = maildir:User quota:ns= quota_exceeded_message = Storage quota for this account has been exceeded, please try again later. quota_rule = *:storage=1G quota_rule2 = Trash:storage=+10%% quota_rule3 = Spam:storage=+20%% quota_status_nouser = DUNNO quota_status_overquota = 552 5.2.2 Mailbox is full quota_status_success = DUNNO quota_warning = storage=90%% quota-warning 90 %u %d quota_warning2 = storage=75%% quota-warning 75 %u %d } protocol imap { mail_plugins = quota notify acl imap_quota imap_acl service replication-notify-fifo { name = aggregator } service anvil-auth-penalty { name = anvil } service auth-worker { name = auth-worker } service auth-client { name = auth } service config { name = config } service dict { name = dict } service login/proxy-notify { name = director } service dns-client { name = dns_client } service doveadm-server { name = doveadm } service imap { name = imap-login } service imap-urlauth { name = imap-urlauth-login } service imap-urlauth-worker { name = imap-urlauth-worker } service token-login/imap-urlauth { name = imap-urlauth } service login/imap { name = imap } service indexer-worker { name = indexer-worker } service indexer { name = indexer } service ipc { name = ipc } service lmtp { name = lmtp } service log-errors { name = log } service pop3 { name = pop3-login } service login/pop3 { name = pop3 } service replicator-doveadm { name = replicator } service login/ssl-params { name = ssl-params } service stats-mail { name = stats } } - 90-quota: passdb { driver = passwd-file args = scheme=CRYPT username_format=%u /etc/dovecot/users } userdb { driver = passwd-file args = username_format=%u /etc/dovecot/users # Default fields that can be overridden by passwd-file #default_fields = quota_rule=*:storage=1G # Override fields from passwd-file #override_fields = home=/home/virtual/%u } Any idea? Already spent hours on this. Thank you in advance for the help. Cheers A.
