dsync backuping folders only, not emails
by Istvan Prosinger 26 Mar '18

26 Mar '18

Hi guys, I have an issue when I try to backup a remote mailbox, apparently it exits with no errors, it creates the mailbox folders in local, but it doesn't copy any email. doveadm -Dv -o dsync_features=empty-header-workaround -o imapc_host=secure.emailsrvr.com -o imapc_password='passwd' backup -R -u somemail(a)counselorinberlin.de imapc: Any hints? All the best, Istvan

Quota set-up problems
by Marcin Norek 26 Mar '18

26 Mar '18

Hi, I've recently started using Dovecot as our main mail storage, and it's performing great. But I have a question/problems with quotas. First of we are using: dovecot --version 2.2.32 (dfbe293d4) Dovecot is a part of a pre set environment (mailcow-dockerized) Aside the inbox namespace we have set-up an additional archive ns (Archiwum) like this namespace Archiwum { type = private separator = / prefix = Archiwum/ location = maildir:/var/vmail/arch/%n:INDEXPVT=~/Maildir/Archiwum subscriptions = yes list = yes mailbox "Wyslane" { auto = subscribe } } It is on an separate disk array, and works well. The problem is that this namespace and all its sub mailboxes should have different quota then the main storage so the config is like this quota = dict:Userquota::proxy::sqlquota quota2 = maildir:ns=Archiwum quota_rule = Trash:storage=+100% quota2_rule = *:ignore It works.. but not as intender. While mail located directly in the name space are ignored everything in sub mailbox of the Archiwum is still accounted to the main quota. I've been fighting this for some time now and can not find the solution. So help would be appreciated. Regards Marcin

destuser setting useless on LMTP proxy
by Jan-Pieter Cornet 26 Mar '18

26 Mar '18

I tried setting the "destuser" setting on the LMTP director as follows, to preserve the original envelope rcpt: protocol lmtp { auth_socket_path = director-userdb passdb { driver = ... override_fields = destuser=%{orig_user} } } The passdb driver would return the appropriate "user" for each alias. Suppose, for example, user1 has emails user1(a)domain.tld, but also alias1(a)domain.tld. Now, it turns out that setting the destuser *changes* the backend. It seems that when the passdb returns "destuser", that username is completely ignored and the hashing of the destuser determines the backend chosen. This is incorrect, the backend should be chosen based on the returned "user", and the "destuser" should only be used for the remote login (or rcpt, in case of LMTP). I'm using version 2.2.35. The problem seems to be in lmtp/commands.c, in client_proxy_rcpt_parse_fields, line 281-285 says: } else if (strcmp(key, "user") == 0 || strcmp(key, "destuser") == 0) { /* changing the username */ *address = value; } ... So it looks as if "user" and "destuser" are treated equally in the LMTP proxy. -- Jan-Pieter Cornet <johnpc(a)xs4all.net> Systeembeheer XS4ALL Internet bv www.xs4all.nl

Config problem: Service #0 is missing name
by Chris Ross 25 Mar '18

25 Mar '18

Okay. So following up on the problems I was discussing weeks ago, I have hand-patched dovecot to work around problems that I believe may be in libc and not dovecot. Trying to get the properly built and installed dovecot-2.2.35, however, is giving me an error I haven’t seen before. I presume that something got munged while I was hand-configuring and installing/uninstalling/reinstalling the port in recent weeks. Running on a FreeBSD 11-stable machine, when I run “service dovecot start”, it tells me: % sudo service dovecot start Starting dovecot. Fatal: Error reading configuration: Invalid settings: Service #0 is missing name /usr/local/etc/rc.d/dovecot: WARNING: failed to start dovecot % Surprisingly, googling for “Service #0 is missing name” didn’t yield a suggestion. My config is the same as it had been previously, I believe. Does anyone have an idea what might be wrong here? Thanks. - Chris

recipient delimiter and sieve filters
by André Rodier 24 Mar '18

24 Mar '18

Dear all, I have found a way to automatically copy sent emails in the "Sent" folder, but I am not sure it is the simplest and more reliable way on the long term. I am open to suggestions if I miss a feature in Dovecot - or Postfix, that allows me to do this. I vaguely remember an SMTP extension that do that, but my memory could be wrong. First, I use "~" as a recipient delimiter. Then, I set up a postfix senders_bcc_map that add the ~Sent part: andre(a)homebox.space → bcc: andre~Sent(a)homebox.space It worked, except that the emails was marked as new. I tried first to add a global sieve filter like this: ---------------------------------------------------------------------- # Sieve script executed before for user require ["fileinto","imap4flags"]; # Move automatically copied emails to the sent folder # And mark them as read if header :contains "Delivered-To" "~Sent" { setflag "\\Seen"; fileinto "Sent"; } ---------------------------------------------------------------------- But it did not work, so maybe there is a trick I am not aware of. If I use the "Received" header and a regex, it works ---------------------------------------------------------------------- require ["fileinto","imap4flags","regex"]; if header :regex "Received" "for <[a-z]+~Sent(a)homebox.space>;" { setflag "\\Seen"; fileinto "Sent"; } ---------------------------------------------------------------------- This is working perfectly, but there is limitations, IMHO. - If the recipient delimiter is not compatible with a regex (e.g. "+"), then the script will probably fail. - Parsing every new email using a regular expression might not be the best option in term of system load. So, I finally use this: ---------------------------------------------------------------------- # Move automatically copied emails to the sent folder # And mark them as read require ["fileinto","imap4flags"]; if header :contains "Received" "~Sent" { setflag "\\Seen"; fileinto "Sent"; } ---------------------------------------------------------------------- My question is why the first one does not work? Does the email has been moved to the Sent folder, and dovecot sieve plugin is not able to find the email any more? Kind regards, André -- https://github.com/progmaticltd/homebox

lmtp service timeouting even after receiving full message
by Arkadiusz Miśkiewicz 23 Mar '18

23 Mar '18

I have a problem with some messages passed from exim to dovecot lmtp service: From exim debug: using socket /var/run/dovecot/lmtp LMTP<< 220 mbox8 ready LMTP>> LHLO mbox8...

Isn't .\n always enough for dovecot to signal end of message? Because exim wrote full message to dovecot lmtp unix socket. Now the interesting this - exim does only one write() with 6585 bytes to write that message to lmtp. If exim needs more than one write() to do that (message is larger by some buffer) then it succeeds, dovecot accepts it. Could dovecot lmtp handling for single write() case be broken? dovecot 2.2.35 -- Arkadiusz Miśkiewicz, arekm / ( maven.pl | pld-linux.org )

Dovecot replication does not replicate subscription in shared mailboxes
by Ralf Becker 23 Mar '18

23 Mar '18

We use a pair of replicating Dovecot servers. If a user subscribes to a folder, shared by an other user, in one replica, that does not get replicated to the other node. Subscription of regular folders below INBOX seem to replicate correctly. Is that a general bug, a known problem or do we need to enable that somehow. Here's our configuration for the concerned namespace: namespace users { location = mdbox:%%h/mdbox:INDEXPVT=~/shared/%%u prefix = user/%%n/ separator = / subscriptions = no type = shared } I attached the full doveconf -n.

How to stop sieve processing to skip sieve_after scripts ?
by Mr Nicolas Belan 23 Mar '18

23 Mar '18

Hello the list, I am trying to achieve filter processing using sieve, but i am not sure I can do what I want. I want to let the user decide to use my filtering script (sieve_after) or not.According to the documentation, i am trying to stop processing in user sieve script, but processing continue. I am using dovecot 2.2 (CentOS). My sieve configuration is:plugin { sieve = /var/vmail/%d/%n/%n.sieve sieve_before = /etc/dovecot/sieve/global-before sieve_after = /etc/dovecot/sieve/global [...]} 'sieve' is the filter script created by users. When trying to stop processing, it is generated by roundcube like:# rule:[deliver to mailbox] if anyof (true) { stop; } 'sieve_after' is the filter which handles the spam processing (fileinto Junk). But the processing continue until all sieve filters are processed: Mar 22 14:50:23 lda(user(a)example.com): Debug: none: root=, index=, indexpvt=, control=, inbox=, alt=Mar 22 14:50:23 lda(user(a)example.com): Debug: Destination address: user(a)example.com (source: -a parameter) Mar 22 14:50:23 lda(user(a)example.com): Debug: sieve: Pigeonhole version 0.4.2 initializing Mar 22 14:50:23 lda(user(a)example.com): Debug: sieve: include: sieve_global_dir is not set; it is currently not possible to include `:global' scripts.

Is it possible ? Perhaps a sieve, sieve2 setting exists ? (like sieve_before, sieve_before2 ...) Thank you for your help, ideas :) Best regards, Nicolas
