Shared mailbox: share whole inbox
by Zdeněk Sobotka 19 Jun '19

19 Jun '19

Hi, I'd like to share the whole INBOX of one user with another. That should go through: doveadm acl add -u user1(a)example.cz SharedDirectory user=user2(a)example.cz lookup read insert It's works fine, when I connect through imap I see: . list "" "*"* LIST (\Noselect \HasChildren) "/" shared* LIST (\Noselect \HasChildren) "/" shared/example.cz/name.surname* LIST (\HasNoChildren) "/" shared/example.cz/name.surname/SharedDirectory* LIST (\HasNoChildren) "/" INBOX. OK List completed (0.000 + 0.000 secs). But now I would like to share the whole INBOX by: doveadm acl delete -u user1(a)example.cz SharedDirectory user1(a)example.cz 2 list "" "*" * LIST (\HasNoChildren) "/" INBOX 2 OK List completed (0.000 + 0.000 + 0.002 secs). doveadm acl add -u user1(a)example.cz INBOX user=user2(a)example.cz lookup read insert 2 list "" "*" * LIST (\HasNoChildren) "/" INBOX 2 OK List completed (0.000 + 0.000 + 0.002 secs). But it doesn't do what I expected, IMAP output it's the same and INBOX in shared folder is not subscribed. I'm looking for help to debug what might be wrong. Thanks.

Is there any way to convert Dovecot's mdbox/dbox to mbox, MailDir or eml format (or any other easy to import format)? Thanks, Adam

per-user mail_max_userip_connections in userdb extra fields
by Eirik Rye 18 Jun '19

18 Jun '19

Hi, The documentation at https://wiki.dovecot.org/UserDatabase/ExtraFields states that "It's possible to override settings from dovecot.conf", as well as the following: > If you want to override settings inside sections, you can separate the > section name and key with '/'. For example: > > namespace default { > inbox = yes > separator = . > location = maildir:~/Maildir > } > > The separator setting can be overridden by returning namespace/default/separator=. extra field. As such, we would expect for it to be possible to override mail_max_userip_connections under the "protocol imap" section, with a passwdfile userdb looking something like this: example:{CRYPT}x:1011:1011::/mail/example::userdb_protocol/imap/mail_max_userip_connections=100 The userdb returns the expected fields in the correct format (according to the documentation): # doveadm user -u example userdb: example user : example uid : 1011 gid : 1011 home : /mail/example protocol/imap/mail_max_userip_connections: 100 However, this new setting is not honoured. To test, I set "mail_max_userip_connections=1" in 20-imap.conf, and noticed that my second connection was closed with the following error: dovecot[13573]: imap-login: Maximum number of connections from user+IP exceeded (mail_max_userip_connections=1) I also attempted the same setting, without the "protocol/imap" prefix. Is this not possible? Are there restrictions to what settings may be overridden in userdb? The documentation appears to suggest that there isn't. Best regards, Eirik Rye

Dovecot LMTP rejecting mail from address with apostrophe
by Michal Krzysztofowicz 18 Jun '19

18 Jun '19

Hi, I have an OpenSMTPD / Dovecot installation on an OpenBSD server. I recently came across an issue where Dovecot LMTP would reject a message sent to a local user from an address which contains a single apostrophe (e.g. firstname.o'lastname(a)example.com) Apparently apostrophe, as well as a number of other special characters, are valid characters in the local part of the email address (that's everything to the left of the @ character). The message I get in the logs is: Jun 14 11:57:34 atlantic smtpd[42606]: 21749fd12ac76b57 mda delivery evpid=56aed6237d6444a0 from=<firstname.o'lastname(a)example.com> to=<me(a)example.org> rcpt=<me(a)example.org> user=me delay=0s result=PermFail stat=Error ("mail.lmtp: LMTP server error: 501 5.5.4 Invalid FROM: Invalid character in localpart") where example.com is external domain and example.org is a local one. The part of the message: LMTP server error: 501 5.5.4 Invalid FROM: Invalid character in localpart is returned by dovecot-lmtp. I’ve had a brief look at the source code, and it seems the responsible code is somewhere inside src/lib-smtp/smtp-address.c and, if I understand the code correctly, the address parsing in actually done in src/lib-smtp/smtp-parser.c. My question is is there a configuration option, similar to auth_username_chars which lists valid characters in the email address, to stop Dovecot LMTP from rejecting such emails? or maybe you know another way of getting it to accept an email from such address? My dovecot version is: $ dovecot --version 2.3.5.1 (7ec6d0ade) And in case that makes any difference, I'm running OpenBSD 6.5 patched to 005_libssl. Thanks!

Problem syncing e-mails with Outlook
by Odhiambo Washington 18 Jun '19

18 Jun '19

Hello all, I am running dovecot- 2.3.5.2 with mdbox storage. I deleted the dovecot.index* from all my folders, which led to mails not being displayed. I rebuilt the indexes for all the users after that, using: doveadm force-resync -u user@domain "*" However, the problem now is that Outlook,configured for IMAP, is not able to sync the mails with the server. I can login to the server using webmail and I see all the e-mails listed. However, when I connect outlook, it does not sync all these e-mails. I am seeing the errors below. Not sure how to fix that.

Deleted dovecot.index.*
by Odhiambo Washington 17 Jun '19

I'm using mdbox. What's the consequence of deleting dovecot.index.* from all folders? All mail gets lost or I can rebuild the indexes and get the mails?

mailbox encryption
by David Mehler 17 Jun '19

17 Jun '19

Hello, I've got dovecot 2.3 going, and I've got a file 10-mailcrypt.conf which is loading mail_crypt, thinking that that plugin would propagate through all the services, sieve, lmtp, and mailbox message storage. I'm not seeing anything in the logs indicating that the encryption is happening. I am using a file format dbox specifically sdbox format, and in my mailbox I am seeing files like u.5 and others, a file check on them reveals them as data. Should I be seeing encryption in the logs? Thanks. Dave.

LDA vs LMTP change in header
by ＠lbutlr 17 Jun '19

17 Jun '19

Switching to dovecot LMTP appears to have change the information in the received header, which appears to be causing my spam filter to wig out and mark local to local emails as spam. Here’s what the received header used to look like: Received: from [10.0.5.3] (c-71-229-144-93.hsd1.co.comcast.net [71.229.144.93]) by mail.covisp.net (Postfix) with ESMTPS id B67B8118AD59 for <kreme(a)kreme.com>; Sun, 16 Aug 2009 22:19:02 -0600 (MDT) As opposed to now: Received: from darth.lan (c-73-14.161.160.hsd1.co.comcast.net [73.14.161.160]) by mail.covisp.net(Postfix 3.4.5/8.13.0) with SMTP id unknown; Sun, 16 Jun 2019 15:26:32 -0600 (envelope-from <kreme(a)kreme.com>) The first has an ESMTPS id and the other has SMTP id unknown, which seems to be causing Spamass-milter to treat the LMTP emails as unauthenticated and then ding them for being from public IPs. -- Thanks to the human heart by which we live, Thanks to its tenderness, its joys, and fears, To me the meanest flower that blows can give Thoughts that do often lie too deep for tears

What does Solr index do and how to handle its high avaliablity?
by luckydog xf 17 Jun '19

17 Jun '19

Hi, guys, Can you give me an example of solr usage in dovecot? As far as I know, you can search email easily by MUA like outlook, so which role does solr play? And based on https://dovecot.org/pipermail/dovecot/2019-April/115575.html I'm going to use an VIP to host 2 mail servers. Currently, it works in fail over and fail back test except solr index, so how to resolve this? Is it possible to put dovecot index on shared storage like NFS? How to if it's a yes. It seems it's under /var/solr/data/dovecot/data/ How to rebuild if I don't put index data on shared storage in case of fail over? Thanks,
