Updated Roadmap for Dovecot?
by Tanstaafl 06 Mar '20

06 Mar '20

Hello, Just wanted to go take a peek at the latest Roadmap for dovecot, and note that the current wiki page is flagged as obsolete: https://wiki.dovecot.org/Roadmap Is there an updated version somewhere? I'm interested in the list of new features being worked on - especially JMAP support - and a rough idea of when said features might be expected to make it into a release. Thanks!

encrypted storage on the fly using user's password without storing password on the server
by Alex Knowles 05 Mar '20

05 Mar '20

Hi all, I just joined the list. I've read through the mail-crypt plugin docs here https://doc.dovecot.org/configuration_manual/mail_crypt_plugin/ I'm still unclear (I'm not an expert) about the following: Is it possible to obtain on-the-fly encrypted storage using the user's password without the password being stored on the server? Basically a zero-knowledge solution. Theoretically this should be possible as the user provides the password when storing or retrieving emails. The above plugin docs don't make it clear for me whether it is supported. Could a kind clarify? I'd also be very grateful for a working conf as an example. Best wishes and thanks in advance, Alex.

[PATCH] lib-imap: imap-bodystructure: add test with empty header field
by Simon Ser 03 Mar '20

03 Mar '20

This causes the body structure to be incorrect. The RFC says it's fine o have empty header field values. --- This just adds a failing test, inspired from an e-mail spotted in the wild.

Dovecot autoexpunge
by Philip Colmer 03 Mar '20

03 Mar '20

Following a previous suggestion I'd received to turn on autoexpunge (https://dovecot.org/pipermail/dovecot/2020-February/118281.html) I'm now trying to confirm whether or not it is doing what I expect it to do. I've set the expiration to be 12 weeks (as shown below in the config) but a lot of the mailboxes have email in them that is much older. Reading http://dovecot.2317879.n4.nabble.com/Dovecot-2-2-20-autoexpunge-td54644.html, I've tried using "doveadm search -u user mailbox INBOX savedbefore 2w" to see if it finds any email that is older than 2 weeks (just as a test) and it doesn't. If I change "savedbefore" to be "sentbefore" then it works. If "autoexpunge" is dependent on "savedbefore" working then what do I need to do to fix this? Thanks.

dovecot-lmtp dont see otherMailbox record?
by pi0trek75 01 Mar '20

01 Mar '20

Hello Postfix + LDAP , Samba as LDAP server, Dovecot virtual_transport set in postfix to dovecot-lmtp ( for autoresponder support ) Users have their email aliases in the otherMailbox record For example, account_test@example-domain user has an alias: test@exmaple-domain Query from command line works fine: postmap -q test@example-domain ldap://etc/postfix/ad_virtual_ account_test/Maildir/ (The filter in the query ad_virtual_mailbox_maps2.cf looks like this: [cut] scope = sub query_filter = (&(objectclass=person)(|(mail= result_attribute= uid result_format = %u/Maildir/ ) However, sending an email to the alias test@example-domain ends: Feb 28 12:31:40 mbox-01 postfix/lmtp[13474]: 2367A6EF: to=<test@example-domain>, relay=mbox-01[private/dovecot- delay=0.05, delays=0.02/0/0.02, dsn=5.1.1, status=bounced (host mbox-01[private/dovecot-lmtp] said: 550 5.1.1 <test@example-domain> User doesn't exist: test@example-domain (in reply to RCPT TO command)) I modified dovecot-ldap.conf.ext: I changed: user_filter = (&(objectClass=person)(uid=%u) to: user_filter = (&(objectClass=person)(|(uid=% but that didn't solve the problem.
