regression with lmtp_hdr_delivery_address in 2.3
by dovecot-ffe7＠ryanc.org 06 May '19

06 May '19

Hi, In my LMTP config, I have lmtp_hdr_delivery_address = none. Under 2.2, Received headers looked like this: Received: from smtp.example.com by lmtp.example.com with LMTP id +IVdKS81cFwWagAAGhmRSA ; Fri, 22 Feb 2019 17:45:19 +0000 After the update to 2.3, they look like this: Received: from smtp.example.com by lmtp.example.com with LMTP id MJbKAMFEclyKCQAAGhmRSA (envelope-from <yyy(a)example.net>) for <xxx(a)example.com>; Sun, 24 Feb 2019 07:16:17 +0000 In both cases I *do not* have a "Delivered-To" header I do see a check for rcpt_to == NULL in the smtp_server_transaction_write_trace_record function, but it looks like the lmtp_local_add_headers function does not update the transaction, so it doesn't get pulled in. Also, the LMTP settings struct isn't exposed in that function currently, and I'm not sure how to add it. In 2.2, both the "Delivered-To" and "Received" headers were handled by client_get_added_headers. Please CC me in replies, as I am not subscribed to the list. Thanks, Ryan

http-lib test failures when building dovecot-2.3.5 and later in mock builder
by Tuomo Soini 06 May '19

06 May '19

There is random failure in test-http-payload when building rpm package from 2.3.6. I couldn't reproduce that in normal system but that happens something like every second try in mock chroot build envirnoment. Other tests don't have issues so it looks like test is not very reliable. Building 2.3.4 didn't yet have this issue. ./test-http-payload -D output attached. -- Tuomo Soini <tis(a)foobar.fi> Foobar Linux services +358 40 5240030 Foobar Oy <https://foobar.fi/>

dynamic virtual mailboxes?
by MRob 06 May '19

06 May '19

hi, I spent time learning about virtual mailboxes. Is there some way to create dynamic virtual mailboxes? I mean, when I look at a mailbox, I want to see only unread messages or flagged messages in that mailbox.

Understanding virtual mailboxes (examples in 15-mailboxes.conf)
by MRob 05 May '19

05 May '19

The examples in 15-mailboxes.conf # If you have a virtual "All messages" mailbox: #mailbox virtual/All { # special_use = \All # comment = All my messages #} # If you have a virtual "Flagged" mailbox: #mailbox virtual/Flagged { # special_use = \Flagged # comment = All my flagged messages #} They seem to reference some kind of virtual mailbox setup that doesn't compare to the docs for the "virtual" plugin. That plugin says we should create a separate namespace instead, like "namespace virtual" and put files representing the virtual folders into user maildirs. What if we use mdbox? add the files to user/mailboxes director I will guess. Is there a way to use the mailbox examples in the inbox namespace in the default config? Does it use some other method different from the virtual plugin? maybe more config hints for those examples would be helpful. Thank you.

Feature request - blacklistd interaction

Would be really really REALLY nice to have dovecot interact directly with blacklistd! Makes a huge difference on busy systems and beats log parsing by far. Thank you

Feature request: additional commands for doveadm HTTP API
by Peter Kubica 04 May '19

04 May '19

Hi, I hope this is correct way of making a feature request. I like doveadm HTTP API very much and use it for Zabbix monitoring. Would be possible to add "replicator status" and "auth test" doveadm commands to HTTP API? Thanks. Kind regards, Peter

It looks like there are some bug fix patches that didn't make it to the 2.3 branch. Peter

Feature request: exclude IP/network in allow_nets extra field
by Zhang Huangbin 01 May '19

01 May '19

Dear all, We use `allow_nets`[1] to restrict login clients, it works fine. Recently we need to allow some users to login from everywhere except some IP/networks, how can we accomplish this with "allow_nets"? Tried allow_nets="!a.b.c.d", but Dovecot reports error "allow_nets: Invalid network '!a.b.c.d'". Can we have this feature? i guess it should be done in function "auth_request_validate_networks"[2] in file src/auth/auth-request.c. [1] allow_nets: https://wiki.dovecot.org/PasswordDatabase/ExtraFields/AllowNets [2] https://github.com/dovecot/core/blob/fbc3ccc4a9a02b82073585a33254eacedc6a99…
