Hi! My "no" referred to the fact that I had not read the article before. =D Thanks for linking it - I'm sure it will be very useful. I've been terribly busy during the last couple of days and have therefore not been able to comment much on the list. I'll come back there as soon as things calm down a bit. =) Yours, Jyri -- +358-50-5632104 (24/7) +358-46-8822157 (backup) jyri.hovila(a)turvamies.fi

Outlook and TLSv.1
by Oliver Welter 20 Jan '15

20 Jan '15

Hi Folks, after adding TLSv1.2 to by TLS options a lot of Outlook users complaint about connection errors, openssl s_client and Thunderbird works fine. I found some posts about this but none of them had a real solution on this - I meanwhile disabled TLSv1.2 which made the Outlook users happy. I run dovecot 2.2.13, OpenSSL 1.0.1j 15 Oct 2014 ssl_cert = </var/qmail/control/servercert.pem ssl_cipher_list = ALL:!EXPORT:!LOW:!MEDIUM:!aNULL:+RC4:@STRENGTH ssl_dh_parameters_length = 2048 ssl_key = </var/qmail/control/servercert.pem ssl_protocols = !SSLv2 !TLSv1.2 The certificate is from Comodo using sha256. Any idea? Oliver -- Protect your environment - close windows and adopt a penguin!

Still receiving Quota warning: mailbox 95% full altough now 20% full
by ML mail 19 Jan '15

19 Jan '15

Hello I am using the quota warnings e-mail feature of dovecot to warn users at 80% and 95%. The issue here is that I have one use who his mailbox is now back down to 20% but he still receives the 95% mailbox full warning mail. Any ideas what could be wrong or what to do? My dovecot config of the mailbox server can be found here: http://article.gmane.org/gmane.mail.imap.dovecot/80823 Regards ML

pigeonhole - how to whitelist
by Cliff Hayes 19 Jan '15

19 Jan '15

Hello, When new users are added we start them with a spam rule that routes spam to their junk folder. I don't see a way to assign priority ... so how does a user whitelist a spam-flagged email? Are the rules applied in some order? Alphabetically perhaps? If so I can name the spam rule z-spam. Thanks in advance.

Shared mailboxes not shown or accessible
by Tim ODriscoll 18 Jan '15

18 Jan '15

Dear All, I'm trying (and failing) to implement a shared mailbox folder. My goal is to share the inbox of a user 'invoices' to a test user 'rubbish'. My ACLs appear to be correct: # doveadm acl get -u invoices inbox ID Global Rights user=rubbish create delete expunge insert lookup post read write write-deleted write-seen The shared-dict is being generated: # cat /var/lib/dovecot/db/shared-mailboxes shared/shared-boxes/user/rubbish/invoices 1 Yet when I try to list the mailboxes, the shared namespace has no children: . login rubbish password . OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS THREAD=ORDEREDSUBJECT MULTIAPPEND URL-PARTIAL CATENATE UNSELECT CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS SPECIAL-USE BINARY MOVE QUOTA ACL RIGHTS=texk] Logged in . list "" "*" * LIST (\HasNoChildren \Trash) "/" Trash * LIST (\HasNoChildren \Drafts) "/" Drafts * LIST (\HasNoChildren \Sent) "/" Sent * LIST (\Noselect \HasNoChildren) "/" shared * LIST (\HasNoChildren) "/" INBOX .

Initial development work on fts-elasticsearch
by Joshua Atkins 18 Jan '15

18 Jan '15

Hi all, I have started work on an ElasticSearch FTS plugin for Dovecot. It's available now on GitHub at: https://github.com/ascendantcom/fts-elasticsearch Please note that it is still in heavy development right now. It supports indexing, searching and expunging with some caveats (no multi-mailbox search or attachments). Pull requests, suggestions and bug reports very welcome! Cheers, Josh

dsync SSL fails since 2.2.15
by Martin Carlé 16 Jan '15

16 Jan '15

Hello list, dovecot ran rock-solid on OSX Mavericks for about 1 year replicating my mail between 2 servers via dsync with SSL as that is well described here: http://wiki2.dovecot.org/Replication After upgrading to 2.2.15, dsync gets stuck with the Error: "Received invalid SSL certificate" even though neither any of the dovecot configs nor the certs, keys or the CA have changed! When I simply outcomment SSL and switch dsync to use tcp (instead of tcps) everthing replications still works like a charm. Please help me to get SSL back working! I did a lot of testing and come up with a concrete QUESTION below, hopefully leading the way out of this trap. What happend ============= 2 days before I upgraded one of the machines to OSX Yosemite. Along with this, I also upgraded to dovecot 2.2.15 via homebrew (unfortunately on both machines at once). During this process, also openssl was updated to "OpenSSL 1.0.1k 8 Jan 2015". If checking the unchanged certs against the CA, however, the results are still "OK". 1st check: OK ========== sudo /usr/bin/openssl verify -CAfile /etc/ssl/ca/dovecotCA.pem /etc/ssl/certs/dovecot_on27_signed_cert.pem Password: /etc/ssl/certs/dovecot_on27_signed_cert.pem: OK 2nd check: OK (providing the CAfile and connecting to the doveadm_port) =========== openssl s_client -CAfile /etc/ssl/ca/dovecotCA.pem -connect on27.linkpc.net:8082 CONNECTED(00000003) depth=1 CN = dovecotCA2, O = dovecot, OU = dovecot, ST = dovecot, C = AF, L = dovecot, emailAddress = mc(a)aiguphonie.com verify return:1 depth=0 CN = on27.linkpc.net, O = dovecot, OU = dovecot, ST = dovecot, C = AF, L = dovecot, emailAddress = mc(a)aiguphonie.com verify return:1 --- Certificate chain 0 s:/CN=on27.linkpc.net/O=dovecot/OU=dovecot/ST=dovecot/C=AF/L=dovecot/emailA… i:/CN=dovecotCA2/O=dovecot/OU=dovecot/ST=dovecot/C=AF/L=dovecot/emailAddress=mc@aiguphonie.com --- Server certificate -----BEGIN CERTIFICATE----- dmVjb3RDQTIxEDAOBgNVBAoMB2RvdmVjb3QxEDAOBgNVBAsMB2RvdmVjb3QxEDAO [...] +g== -----END CERTIFICATE----- subject=/CN=on27.linkpc.net/O=dovecot/OU=dovecot/ST=dovecot/C=AF/L=dovecot/… issuer=/CN=dovecotCA2/O=dovecot/OU=dovecot/ST=dovecot/C=AF/L=dovecot/emailAddress=mc(a)aiguphonie.com --- No client certificate CA names sent --- SSL handshake has read 1709 bytes and written 487 bytes --- New, TLSv1/SSLv3, Cipher is ECDHE-RSA-AES256-GCM-SHA384 Server public key is 2048 bit Secure Renegotiation IS supported Compression: zlib compression Expansion: zlib compression SSL-Session: Protocol : TLSv1.2 Cipher : ECDHE-RSA-AES256-GCM-SHA384 Session-ID: C4DDBA1FA50039FA5D94EF2359BA037B3903D66B6B637CA0733A9216BFCC3996 Session-ID-ctx: Master-Key: 0495D21CA11AA54856D78B48C3DBE9B70EFFB65F13224B430D2B4B2F80F12BE5A89F31454F9577F22F5DDC26FDBAAFAC Key-Arg : None PSK identity: None PSK identity hint: None SRP username: None TLS session ticket lifetime hint: 300 (seconds) TLS session ticket: [...] 0090 - 2d 97 37 15 bd a9 be 68-c1 79 fa dd d8 75 76 3f -.7....h.y...uv?

Is there a call to the openssl cmd or is the library linked into dovecotadm? If liked, what version is used and how can I possibly change it? or: What's wrong with my CA and cert(s) all of a sudden? How can I create new CA for two certs fitting the (new) needs of dovecotadm?
