sieve filter move wrong email to Junk folder
by Gao 15 Dec '17

15 Dec '17

I use a sieve filter to move spam email to user's Junk folder: # cat spam_to_junk.sieve require "fileinto"; if exists "X-Spam-Status" { if header :contains "X-Spam-Status" "YES" { fileinto "Junk"; stop; } else { } } if header :contains "subject" ["SPAM?"] { fileinto "Junk"; stop; } Most time this filter works fine but occasionally it move non-spam in to Junk folder. Here is an example, this email is from dovecot mailling list and it end up in my Junk folder. Mailllog and header here. Would someone help me to figure out what went wrong here? Thanks.

doveadm log reopen not works with 2.2.33
by Alessio Cecchi 14 Dec '17

14 Dec '17

Hi, after the upgrade from dovecot 2.2.32 to 2.2.33 we notice that the /var/log/director/director.log was empty and the log are write in the logrotate file es. /var/log/director/director.log-20171201. Log path is dovecot is: log_path = /var/log/director/director.log Logrotate configuration is: /var/log/director/director.log { daily rotate 31 missingok notifempty compress delaycompress sharedscripts postrotate doveadm -i director log reopen endscript } and worked fine until the last dovecot upgrade. Now the only way to "reopen" the log file is doveadm reload. Is this a know bug? Thanks -- Alessio Cecchi Postmaster @ http://www.qboxmail.it https://www.linkedin.com/in/alessice

Just to be clear, if at any point your VPS has access to the plaintext mail (or keys that decrypt mail), then the VPS provider could access your decrypted mail. To make it unfeasible for your VPS to read your mail, it has to arrive at your VPS pre-encrypted. I can envision a system where you import encrypted mail into your mail store, then use client IMAP access to be decrypted locally by your mail reader. However, metadata is still accessible by your VPS provider. If your VPS is the MTA that directly handles SMTP from your correspondees sending you unencrypted messages, you can't lock out a sufficiently skilled platform admin.

TLS Error and not working lmtp
by Jakob Schürz 13 Dec '17

13 Dec '17

Hi! I have some troubles with the virtual plugin. I run a self-compiled dovecot 2.2.33.2 from debian testing. I patched this version with the QRESYNC-Patch from a few weeks ago. But i always get an errormessage, when i try to open an email from a virtual mailbox. So i cloned the actual git-Repo and compiled dovecot and pigonehole-sieve. The problem with the virtual plugin seems gone away. But there are some other problems. I use ssl=required and with dovecot from debian TLS/SSL and STARTTLS works fine. With the selfcompiled from git, i get this error: dovecot[1284]: imap-login: Error: Failed to initialize SSL server context: Couldn't parse DH parameters: error:0906D06C:PEM routines:PEM_read_bio:no start line: Expecting: DH PARAMETERS: user=<>, rip=127.0.0.1, lip=127.0.0.1, secured, session=<D6bC4Rlg8ut/AAAB> The key and crt are exactly the same files as before. The second problem is, lmtp is not working. I use exactly the same config for the debians dovecot and dovecot from git. But in the gitversion the error in exim is: Failed to connect to socket /var/run/dovecot/lmtp for dovecot_lmtp transport: Connection refused My config is: # dovecot -n # 2.3.devel (b1aac3a1d):

Recommended tool for migrating IMAP servers
by Davide Marchi 12 Dec '17

12 Dec '17

Hi Friends, I would like to ask you a suggestion: I need to migrate a imap server to a new one and then dismiss the old one. Reading from relative Dovecot documentation page (https://wiki.dovecot.org/Migration) more tools are shown: UW-IMAP's mailutil, imapsync, YippieMove and Larch. The each mail servers are Linux based, one of this (mine) is Dovecot. Based on your experience which of these tools would be preferable to use? Thank you very much Davide
