I'm trying to make my github processing better, but I'm missing something. I have the following: if address :all :contains "from" ["github.com"] { addflag "github"; addflag "MyFlags" "github"; set "mailbox" "GitHub"; if address :matches :user "to" "*" { set "GHUser" "${1}"; addflag "${GHUser}"; addflag "MyFlags" "${GHuser}"; } if header :matches "List-ID" "(.*/.*) <(.*)>" { set "mailbox" "github-lists/${1}"; } fileinto :flags "${MyFlags}" :create "${mailbox}"; stop; } I'm trying to match the apache-incubator-superset part of: List-ID: apache/incubator-superset <incubator-superset.apache.github.com> What am I missing? -- Larry Rosenman http://www.lerctr.org/~ler Phone: +1 214-642-9640 (c) E-Mail: larryrtx(a)gmail.com US Mail: 5708 Sabbia Dr, Round Rock, TX 78665-2106

doveadm backup mdbox - initial copy slow
by Gerald Galster 30 Aug '19

30 Aug '19

Hello, when calling doveadm backup like in the following example, it seems to flush every email to disk maxing out harddrives (iops) and resulting in very poor performance: Calling doveadm -o plugin/quota= backup -u "statusmails(a)domain.com" "mdbox:/backup/vmail/domain.com/statusmails" finished in 212 secs [changes:1800 copy:1800 delete:0 expunge:0] The source mdbox holds 1800 small emails and uses about 20 MB disk space only. I've tried -f (full sync) and -l 30 (locking the mailbox) which did not get faster, nor did doveadm sync -1. When using doveadm import all mails are copied in less than 3 seconds: time doveadm -o mail=mdbox:/backup/vmail/domain.com/statusmails import mdbox:/var/vmail/domain.com/statusmails "" all real 0m2.605s Are there any other options I could try to speed up doveadm backup, avoiding the flush after each email? This is doveadm from dovecot 2.2 (>= 2.2.33). Does anyone get better results with 2.3 tree? Best regards Gerald

User / Pass SQL queries
by Michael Hallager 29 Aug '19

Hi all, Is there any reason Dovecot shows the 'user' variable (ie: user(a)domain.tld) being obtained in the password query and not the (more logical) user query? Thanks, Michael

Feature wishlist: Allow to hide client IP/host in submission service
by Sebastian Krause 28 Aug '19

28 Aug '19

Hi, In many mail setups a required feature (for privacy reasons) is to hide the host and IP of clients (in the "Received" header) that use the authenticated submission over port 587. In Postfix that's possible (https://serverfault.com/q/413533/86332) but not very nice to configure especially if you only want want to strip the Received header for port 587 submissions, but not on port 25. As far as I can see this configuration is not possible at all in the Dovecot submission server because the function which adds the Received header with the client's IP address (smtp_server_transaction_write_trace_record) is always called in submission-commands.c. It would be very useful if the submission server could anonymize the client with a single configuration option, then all the Postfix configuration mess (and using SASL) could be skipped by simply using the Dovecot submission server instead. The anonymization would work by replacing the client's EHLO host with "submission" and the IP address with 127.0.0.1. In full the Received header would look something like this where the first line is always the same: Received: from submission (unknown [127.0.0.1]) by mail.example.com with ESMTPSA id 8bV9D+51Yl1FOwAA1ctoJQ (envelope-from <john(a)example.com>) for <jane(a)example.com>; Sun, 25 Aug 2019 13:50:06 +0200 Sebastian
