NOTIFY: bug on mailbox renaming and deletion ?
by kael 16 Jun '19

16 Jun '19

Hello, Testing the NOTIFY extension on imap.vivaldi.net, seems there's a bug when a mailbox is renamed or deleted. Requesting events with: A1 NOTIFY SET (inboxes (SubscriptionChange MailboxName)) Here are the sent events: - mailbox creation with automatic subscription (ok): * LIST () "." foo * LIST (\Subscribed) "." foo - mailbox renaming (bug ?): * LIST () "." bar ("OLDNAME" (foo)) * LIST (\Subscribed) "." bar * LIST () "." foo - mailbox deletion (bug ?): * LIST (\NonExistent) "." Trash.bar * LIST () "." Trash.bar It seems that for the two latter cases, the last received event is incorrect, Dovecot notifying of mailbox unsubscription after the mailbox has been renamed or deleted. In that case a client would consider those two last events not as mailbox renaming or deletion, but as a mailbox creation, wouldn't it ? Am I missing something ? Cheers. -- kael

Dovecot 2.3 error, FreeBSD 12 in a jail
by David Mehler 15 Jun '19

15 Jun '19

Hello, I'm trying to get Dovecot going on my system. It's a FreeBSD 12.0-RELEASE system and it's running dovecot 2.3 via ports in a jail. I'm getting the same error message(s) as in this bug report, which has been marked as closed: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=225078 Dovecot is not starting at all in this jail when starting with service dovecot start. A service dovecot status also reveals the error message about /var/run/dovecot/dovecot.conf file, but a doveconf -n does not reveal any configuration file issues. I did put a symlink in /var/run/dovecot to /usr/local/etc/dovecot/dovecot.conf, this did not correct the issue. Any suggestions welcome. Thanks. Dave.

LMTP doesn't save to +mailbox
by ＠lbutlr 14 Jun '19

14 Jun '19

Since switching to lmtp in dovecot, mail to user+mailboix(a)example.com does not get saved in ‘.mailbox’ as it did with LDA, instead it gets saved into the INBOX. If it matters, these are users who do NOT have a ~/.active_sieve file. I could understand (though it would bene a bit annoying) if the save overrode this mechanism. I did add lmtp_save_to_detail_mailbox = yes in the protocol lmtp block protocol lmtp { postmaster_address = postmaster(a)covisp.net # required mail_plugins = quota sieve info_log_path = /var/log/dovecot-lmtp.log lmtp_save_to_detail_mailbox = yes } This is the error I am getting when sending to luser+covisp(a)covisp.net lmtp(luser(a)covisp.net)<91193><EqkiJV70A105ZAEAIdGjjQ>: Error: sieve: msgid=<A3ED963A-97FB-4A1F-9F09-45F2AEA96CF6(a)kreme.com>: failed to store into mailbox 'covisp': Mailbox doesn't exist: covisp lmtp(luser(a)covisp.net)<91193><EqkiJV70A105ZAEAIdGjjQ>: Error: sieve: Execution of script /usr/lib/dovecot/sieve/default.sieve failed with unsuccessful implicit keep # cat /usr/lib/dovecot/sieve/default.sieve [13:32] [/var/log] require "fileinto"; if header :contains "X-spam-flag" "YES" { fileinto "Junk"; } (This file hasn’t changed in a year, so it worked fine with the lda instead of the lmtp setup.

Dovecot director: show user breakdown by director?
by Eirik Rye 14 Jun '19

14 Jun '19

Hi, We have recently started using the director in some tests. We are using the static passdb setup (proxy=y nopassword=y) for now, where authentication is done on the downstream IMAP servers. "dovecot director status" shows a breakdown of proxied connections per backend, but there does not seem to be a similar breakdown of user connections per director. The output of "doveadm who" is empty. I assume this is due to there being no local userdb/passdb on the directors? root@xxx:/etc/dovecot/conf.d# doveadm who username # proto (pids) (ips) Is there a way in Dovecot to see which (or even how many) users are connected to a specific director without having to count TCP connections? Best regards, Eirik Rye

Addheader specified field name `Reply-To:' is invalid.
by ＠lbutlr 14 Jun '19

14 Jun '19

Well, progress. At least now editheader loads. Sadly that brings up new errors. specified field name `Reply-To:' is invalid. if header :contains "List-id" "<users.spamassassin.apache.org>" { addheader "Reply-To:" "<users.spamassassin.apache.org>"; addheader "X-added-reply-To:" "True"; fileinto :create “spamassassin"; stop;} -- You only had to look into Teatime's mismatched eyes to know one thing, which was this: if Teatime wanted to find you he would not look everywhere. He'd look in only one place, which would be the place where you were hiding. —Hogfather

MultiMaster dsync (cluster1 cluster2 cluster3)
by Matthew Brown 14 Jun '19

14 Jun '19

Will MultiMaster dsync work fine or will be big problems ? I configured dovecot to dsync from serv1 to serv2 to serv3 and repeat to serv1 to serv2 to serv3 and repeat... When email received to serv2, it will be synced to serv3, and serv3 will sync it to serv1, and serv1 will sync it to serv2 and will stop here because emails matched. What problems can be with this kind of configuration ? (except that if one of server(cluster) will be stopped, sync will be stopped too until cluster is online again)

Sieve rewrite headers?
by ＠lbutlr 14 Jun '19

14 Jun '19

I’ve bene looking for examples on how to do this, but so far am coming up short. I want to check certain messages for a reply-ro header and if it is present, rewrite it to X-Reply-To: and then add my own reply-to header. I don’t see anything in the various sieve examples I’ve found on altering the actual message. There is the editheader extension, but I failed to find documentation or examples on how to use it. It appears that I can add a header and delete a header (addheader deleteheader?) but not rewrite one. So something like if header “Reply-to: foo(a)bar.xn--tld-9o0a { addheader "X-Reply-To: foo(a)bar.xn--tld-9o0a deleteheader “Reply-To:” addheader "X-Reply-To: bar(a)foo.xn--tld-9o0a } ?? Do I need to delete the header or will the add header overwrite the one that is there? Also, how do people manage different sieve files? Just cat them all into the active one, or is there a mechanism to import/switch/load other files?
