update to my first email
by Christy S 19 Aug '18

19 Aug '18

Alright so after checking logs, rebooting the vps because why not, and removing and re-adding the account in thunderbird... Now nothing is working other than sending mail from gmail to the domain. imap does not pick up the email and trying to send with the domain just plain fails, saying it can't connect to the server. Honestly, tempted to uninstall dovecot, sasl and postfix and start again, but I don't want to run into the same issues with conflicting tutorials. Does anyone know of a good source of how to do this that's fairly recent? I'll keep searching, but all of the outdated info is kind of frustrating. If anyone has replied to me I haven't gotten it yet, so I'm not ignoring anything you may have said. For now going to give this a break. I've been working on it literally all day! :) Christy

Hello, has anyone experiened any issues with IMAP SPECIAL-USE extension with ios11? After the update to ios11 the Ios mail client seems to not recognize anymore the imap special-use, so that system folders (Sent, Trash etc..) are not authomatically recognized and set during the configuration.

"nologin" field set leads to internal failure
by postminion＠dicksinmyan.us 17 Aug '18

17 Aug '18

Hi, I've tried to use the "nologin" extra password-db field as specified here: https://wiki.dovecot.org/PasswordDatabase/ExtraFields/NoLogin Due to lack of exact documentation, I've tried to use `nologin`='y' for users that can't login, and setting `nologin`='n' for normal users. Apparently setting it to NULL for normal users would have been correct, as I've found out. Maybe write that on the above website. Anyway, login didn't work for a user with `nologin`='n' set. Trying to debug a normal user being unable to login, the log (mail.log) says: dovecot: imap-login: Disconnected (internal failure, 4 successful auths): user=<test(a)example.com>, method=PLAIN, rip=<ip6>, lip=<ip6>, TLS, session=<session> What I'm expecting it to say would be something like "user not allowed to login". I'm considering this a problem because of "Dovecot always logs a detailed error message if something goes wrong." as written here: https://wiki2.dovecot.org/Logging For the record, setting auth_debug=yes and mail_debug=yes gave the following line in the logs somewhere, from which I was able to figure out that NOLOGIN was the problem: dovecot: auth: Debug: client passdb out: OK#011<id>#011user=test(a)example.com#011nologin Thank you. dovecot -n output: --snip-- # 2.2.27 (c0f36b0): /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.16 (fed8554) # OS: Linux 4.9.0-7-amd64 x86_64 Debian 9.5 auth_default_realm = example.com base_dir = ... listen = *,[v6] login_greeting = ... mail_home = .../%d/%n/ mail_location = maildir:~/mail/:INDEX=MEMORY mail_plugins = trees mail_temp_dir = ... namespace inbox { inbox = yes location = prefix = } passdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } protocols = imap lmtp recipient_delimiter = -+ service auth { unix_listener ... { group = postfix mode = 0660 user = postfix } } service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 0 } service_count = 1 } service lmtp { unix_listener ... { group = postfix mode = 0600 user = postfix } user = vmail } ssl = required ssl_cert = <... ssl_cipher_list = ... ssl_dh_parameters_length = 4096 ssl_key = # hidden, use -P to show it userdb { driver = prefetch } userdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } --snap--

sdbox filesystem backup potential excludes
by Daniel Miller 17 Aug '18

17 Aug '18

When doing a filesystem backup of an moderate sdbox mailstore (300GB) - are there any files that can be safely excluded from the backup? Like *.log or *.backup? Or are they all "vital" for recovery? I'm already excluding the sdbox/virtual folders as it looks like they get created and updated as needed. -- Daniel

imapsieve wrong matches on APPEND cause
by Alex Cherevko 16 Aug '18

16 Aug '18

Hello, I'm experiencing some strange problem with imapsieve mailbox rules matching. I have Ubuntu Server 18.04.1 LTS with Postfix 3.3.0, Dovecot 2.2.33.2 and Rspamd 1.7.9. The problem occurs with Microsoft Outlook 2016 mail client. When moving with Outlook, APPEND event is logged instead of MOVE. However, when moving with another client, MOVE event is logged. So without APPEND event in causes in plugin section of dovecot.conf no rule is matched at all. If I add APPEND event into causes in plugin section of dovecot.conf, then for some reason imapsieve matches both rules on move from Inbox to Spam and no rules on move from Spam to Inbox. Matching both rules attempts to run both learn_spam and learn_ham. First one works and second logs error (which is correct). On attempt to move message from Spam to Inbox imapsieve not matching any rule at all and thus learning is not working. Could you please let me know how to fix this? More details. Here is what I have in my plugin section of dovecot.conf: ---------------------------------------- %< ---------------------------------------- plugin { imapsieve_mailbox1_before = file:/var/vmail/sieve/global/learn-spam.sieve imapsieve_mailbox1_causes = COPY APPEND imapsieve_mailbox1_from = Inbox imapsieve_mailbox1_name = Spam imapsieve_mailbox2_before = file:/var/vmail/sieve/global/learn-ham.sieve imapsieve_mailbox2_causes = COPY APPEND imapsieve_mailbox2_from = Spam imapsieve_mailbox2_name = Inbox sieve = file:/var/vmail/sieve/%d/%n/scripts;active=/var/vmail/sieve/%d/%n/active-scr ipt.sieve sieve_before = /var/vmail/sieve/global/spam-global.sieve sieve_global_dir = /var/vmail/sieve/global/ sieve_global_extensions = +vnd.dovecot.pipe +vnd.dovecot.environment +vnd.dovecot.debug sieve_pipe_bin_dir = /usr/bin sieve_plugins = sieve_imapsieve sieve_extprograms } ---------------------------------------- %< ---------------------------------------- I also have Trash, Drafts, Sent and Spam mailboxes defined in dovecot.conf. So when I try to move actual spam message from Inbox to Spam folder, this is what I see in dovecot.log: ---------------------------------------- %< ---------------------------------------- Debug: imapsieve: mailbox Spam: APPEND event ---------------------------------------- %< ---------------------------------------- So before I added "APPEND" into above imapsieve_mailbox1_causes and imapsieve_mailbox2_causes imapsieve was not matching rules at all. But after I added APPEND, here is what happens. In case I move message from Inbox to Spam both rules are matched and dovecot attempts to run both rules: ---------------------------------------- %< ---------------------------------------- Debug: INBOX: Mailbox opened because: SELECT Debug: Spam: Mailbox opened because: SELECT Debug: imapsieve: mailbox Spam: APPEND event Debug: sieve: Pigeonhole version 0.4.21 (92477967) initializing Debug: sieve: Sieve imapsieve plugin for Pigeonhole version 0.4.21 (92477967) loaded Debug: sieve: Sieve Extprograms plugin for Pigeonhole version 0.4.21 (92477967) loaded Debug: imapsieve: Static mailbox rule [1]: mailbox=`Spam' from=`*' causes=(APPEND) => before=`file:/var/vmail/sieve/global/learn-spam.sieve' after=(none) Debug: imapsieve: Static mailbox rule [2]: mailbox=`*' from=`Spam' causes=(APPEND) => before=`file:/var/vmail/sieve/global/learn-ham.sieve' after=(none) Debug: imapsieve: Matched static mailbox rule [2] Debug: imapsieve: Matched static mailbox rule [1] Debug: sieve: file storage: Using Sieve script path: /var/vmail/sieve/global/learn-spam.sieve Debug: sieve: file script: Opened script `learn-spam' from `/var/vmail/sieve/global/learn-spam.sieve' Debug: sieve: file storage: Using Sieve script path: /var/vmail/sieve/global/learn-ham.sieve Debug: sieve: file script: Opened script `learn-ham' from `/var/vmail/sieve/global/learn-ham.sieve' Debug: sieve: Opening script 1 of 2 from `/var/vmail/sieve/global/learn-spam.sieve' Debug: sieve: Loading script /var/vmail/sieve/global/learn-spam.sieve Debug: sieve: Script binary /var/vmail/sieve/global/learn-spam.svbin successfully loaded Debug: sieve: binary save: not saving binary /var/vmail/sieve/global/learn-spam.svbin, because it is already stored Debug: sieve: Executing script from `/var/vmail/sieve/global/learn-spam.svbin' Debug: sieve: action pipe: running program: rspamc Debug: Mailbox Spam: Opened mail UID=12 because: mail stream Debug: waiting for program `/usr/bin/rspamc' to finish after 0 msecs Debug: sieve: Opening script 2 of 2 from `/var/vmail/sieve/global/learn-ham.sieve' Debug: sieve: Loading script /var/vmail/sieve/global/learn-ham.sieve Debug: sieve: Script binary /var/vmail/sieve/global/learn-ham.svbin successfully loaded Debug: sieve: binary save: not saving binary /var/vmail/sieve/global/learn-ham.svbin, because it is already stored Debug: sieve: Executing script from `/var/vmail/sieve/global/learn-ham.svbin' Debug: Spam: Mailbox opened because: lib-lda delivery Debug: Spam: Mailbox opened because: SELECT ---------------------------------------- %< ---------------------------------------- And of course I'm getting the following in the log file: ---------------------------------------- %< ---------------------------------------- Error: sieve: learn-ham: line 2: duplicate pipe "rspamc" action not allowed (previously triggered one was here: learn-spam: line 3) Error: sieve: Execution of script /var/vmail/sieve/global/learn-ham.sieve failed ---------------------------------------- %< ---------------------------------------- In case I move message from Spam to Inbox on rule is matched at all: ---------------------------------------- %< ---------------------------------------- Debug: INBOX: Mailbox opened because: SELECT Debug: imapsieve: mailbox INBOX: APPEND event Debug: sieve: Pigeonhole version 0.4.21 (92477967) initializing Debug: sieve: Sieve imapsieve plugin for Pigeonhole version 0.4.21 (92477967) loaded Debug: sieve: Sieve Extprograms plugin for Pigeonhole version 0.4.21 (92477967) loaded Debug: imapsieve: Static mailbox rule [1]: mailbox=`Spam' from=`*' causes=(APPEND) => before=`file:/var/vmail/sieve/global/learn-spam.sieve' after=(none) Debug: imapsieve: Static mailbox rule [2]: mailbox=`*' from=`Spam' causes=(APPEND) => before=`file:/var/vmail/sieve/global/learn-ham.sieve' after=(none) Debug: INBOX: Mailbox opened because: SELECT ---------------------------------------- %< ---------------------------------------- With best regards, Alex

I'm sorry you got bit by this, it's the spam filter. The way to get by the spam filter is to subscribe and wait about an hour for the subscription list to be updated, then you can post to the list, as we give a high negative score for anyone subscribed.

If the goal is to ensure privacy using a third-party storage provider (and assuming mail handlers are implictly trusted), it seems more productive to invest effort into block/FS level encryption that comprehensively protects all data.
