TFA authentication in dovecot, using XMPP and RFC 4226
by André Rodier 03 Apr '19

03 Apr '19

Hello, I would like to implement some kind of two factors authentication, in Dovecot. I am thinking about using the post login script, to check for unusual behaviour, like say, a different country / IP address or an unusual hour. I already wrote a simple shell script that check these factors, but now, I have some options for the following, and I need to know your opinion if this is feasible or not. I want to use google authenticator Debian package (support the HMAC- Based One-time Password (HOTP) algorithm specified in RFC 4226 and the Time-based One-time Password (TOTP)) The challenge would be send via XMPP. This second part is fairly easy to do, I have all the packages on Debian, for instance sendxmpp. The first tests are promising. In case of success, the IP address is added to the list, let's say for one month... My back-end for authentication is OpenLDAP. My questions are: - Do you see any performance issues for other users or login processes, if I implement this? - I am planning to use a timeout, for instance one minute to confirm the connection. Does Dovecot have a timeout on its side, that would abort the connection before? Otherwise: - Is it possible to have multiple authentication back-ends in Dovecot? For instance LDAP and/or OTP? - I think to have seen some TFA options in Dovecot, but AFAICS, they are mandatory. Thanks for your insights, and this fabulous software. -- André Rodier HomeBox: https://github.com/progmaticltd/homebox

where shall I enforce sieve and quota plugins

Hello, guys, I'm going to using sieve and quota plugins, but I'm not sure where shall I enforce against properly? I see somebody uses them against 20-imap.conf, 15-lda.conf, or 20-lmtp.conf I use LMTP as MDA, so where is the correct location to call these plugins and why? Thanks,

Trying to track down source of duplicate messages
by Alex 02 Apr '19

Hi, I have a fedora28 system with dovecot-2.3.5 and I'm trying to figure out why I'm increasingly receiving duplicate emails. The message IDs are exactly the same. It's always two of the same messages. I don't think it's ever occurred in the inbox. It doesn't happen with every message or seemingly in every folder. I've read about dovecot deduplicate, but of course I want to prevent them from being duplicated in the first place. It's also happening much more frequently now. Could something in my configuration cause this problem? Below is the contents of my doveconf # 2.3.5 (513208660): /etc/dovecot/dovecot.conf # Pigeonhole version 0.5.5 (2483b085) # OS: Linux 4.20.11-100.fc28.x86_64 x86_64 Fedora release 28 (Twenty Eight) #

ssl_min_protocol
by ＠lbutlr 02 Apr '19

02 Apr '19

What are the possible settings for ssl_min_protocol? I only see it on the upgrade page where it mentions the default is TLSv1. Searching on the dovecot page gives me "Your search query "ssl_min_protocol" didn't return any results." -- Up the airy mountains, down the rushy glen...

sql table definitions
by Richard Hector 02 Apr '19

02 Apr '19

Hi all, Trivial question ... I'm using PostgreSQL for my auth db. I used the example CREATE TABLE statement in the config file, but now I find the fields are too short. I assume dovecot will be fine with 'text' type columns replacing the varchars? Or failing that, I can change the length of the varchar fields? Cheers, Richard

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Hi, are there any known issues with dovecot/director (2.2.13) when receiving e-an mail with multiple receivers?

mail_crypt not working on incoming messages?
by Dave 01 Apr '19

01 Apr '19

[Dovecot v2.2.33.2] I'm testing out mail_crypt on a fresh Dovecot install to get a feel for how it works, but I'm running into something unexpected. The mail_crypt plugin does seem to be working, but NOT on incoming email. What I mean is, if I send a test email to the server that has Dovecot installed, the message correctly arrives in the user's Maildir folder (I'm using Maildir format, not mbox), as I can see the mail message file appear. However, the message file is in plaintext and is not encrypted. But, if, using my Thunderbird email client connected to that account via IMAP, I move that message out of the inbox of that account to a folder on another account, and then move it back in to the original inbox, the file that appears in the Maildir folder structure IS encrypted. I have confirmed that mail_crypt is active in 10-mail.conf, 20-imap.conf, and 20-pop3.conf. The global public and private keys are working because (a) there are no errors and (b) it DOES encrypt -- just not on incoming email. mail_crypt_save_version is set 2, as per the docs for Dovecot 2 instruct. What am I missing? Does anyone have any thoughts as to why JUST incoming messages aren't encrypted, but that messages moved into the IMAP account DO get encrypted? Did I set up something incorrectly? I'm using sendmail as the MTA, if that matters, and messages are routed to the user's Maildir folder structure using a .procmailrc in that user's home folder. -Dave

dovecot ssl error message from my own connections
by Esteban L 01 Apr '19

01 Apr '19

Hello all, Just a minor thing. Not a big deal, because everything works fine, and I feel secure with my setup. But, I get this error message pretty much throughout the day/night, which appears to come from my own mail clients (desktop or mobile). I would like to resolve it, because it must me something (that is not good--that I may not understand), that may have other ramifications. So, here it is. date time myserver dovecot: imap-login: Debug: SSL error: SSL_read() syscall failed: Connection reset by peer Anyone have a suggestion of what this might hint to, other than obvious SSL. I tried parsing through various logs, but the most I find is just this single line. I can produce it, whenever I close my email client. Thanks in advance.

Possible bug with last_login plugin and PostgreSQL
by Zhang Huangbin 01 Apr '19

01 Apr '19

Dear all, I'm trying to get last_login plugin working with PostgreSQL, but seems Dovecot doesn't handle duplicate key while updating last login time (note: same setting works fine with MariaDB).

Purges now happen 5 times faster
by Steve Litt 29 Mar '19

29 Mar '19

Hi all, I use Claws-Mail to look inside my local (same metal) Dovecot server. All incoming mail is dumped into Dovecot folders via procmail. All of a sudden today, mass purges of "marked for delete" happen about 5 times faster. The process used to be a significant productivity destroyer, but now is easy to work with. In other words, it's a good thing, but until I know why this happened, I'll have that little voice inside telling me there's some evil side effect somewhere. Does anybody know any reason this should have happened? I'm using Dovecot 2.3.5 (513208660) and Claws-Mail 3.17.3. Thanks, SteveT

Hi, I've been having an issue with the indexer giving me errors on mailbox in dovecot. I managed to narrow it down to a specific email in that mailbox. Various dovecot functions have issues with this email. The email itself is just spam. I can email it to you if you want to analyse it. I did run it through mbox-anonymize but its not clear to me that that would be of any use. Happy to email the suspect email privately to anyone who wants it. /home is mounted nfs4 and is zfs on the nfs server.

Apparmor problem
by Ervin Hegedüs 28 Mar '19

28 Mar '19

Hi there, I know this isn't a Dovecot issue, but hope that somebody can helps me. I've successfully installed and configured Dovecot to a Debian 9 server. Looks like everything works as well, I just see a line in the log when I send a mail: Mar 28 22:21:47 mailng kernel: [3150146.825007] audit: type=1400 audit(1553808107.757:286204): apparmor="DENIED" operation="open" profile="/usr/lib/dovecot/dovecot-lda" name="/usr/share/dovecot/protocols.d/" pid=26197 comm="doveconf" requested_mask="r" denied_mask="r" fsuid=5000 ouid=0 The /usr/share/dovecot/protocols.d/ directory and its content (.../protocols.d/**) set up in usr.lib.dovecot.dovecot-lda apparmor profile with mask "r", but this line every time comes, when I send a mail through webmail - think when the client copies the message to the Sent folder (anyway, the sent messages are in Sent folder after sending, so everything works). Do you have any idea? Thanks, a.

Regression ACL & namespace prefix
by Michal Hlavinka 28 Mar '19

28 Mar '19

Hi tl;dr: Seems that for Global ACL directory, namespace prefix is not part of the path, when looking for acl file. Long version: We're planning to update dovecot in next os update to 2.2.36 and while going through regression testing, we found a problem with ACL configuration combined with namespace. Test uses "Global ACL directory" configuration. Relevant configuration part: mail_location = maildir:~/Maildir namespace inbox { hidden = no inbox = yes list = yes location = prefix = separator = / } namespace { hidden = no list = yes location = maildir:/var/mail/pub prefix = pub/ separator = / type = public } mail_plugins = acl protocol imap { mail_plugins = $mail_plugins acl imap_acl } plugin { acl = vfile:/etc/dovecot/global-acls } ACL config file is stored at: /etc/dovecot/global-acls/pub/.DEFAULT when trying to examine "pub", it is denied: fetchmail: IMAP> A0005 EXAMINE "pub" fetchmail: IMAP< A0005 NO Mailbox doesn't exist: pub (0.001 + 0.000 secs). # doveadm acl debug -u d2 pub doveadm(d2): Info: Mailbox '' is in namespace 'pub/' doveadm(d2): Info: Mailbox path: /var/mail/pub doveadm(d2): Info: All message flags are shared across users in mailbox doveadm(d2): Info: User d2 has no rights for mailbox doveadm(d2): Error: User d2 is missing 'lookup' right doveadm(d2): Info: Mailbox pub is NOT visible in LIST because it did not find acl file: imap(d2): Debug: Namespace : type=public, prefix=pub/, sep=/, inbox=no, hidden=no, list=yes, subscriptions=yes location=maildir:/var/mail/pub imap(d2): Debug: maildir++: root=/var/mail/pub, index=, indexpvt=, control=, inbox=, alt= imap(d2): Debug: acl: initializing backend with data: vfile:/etc/dovecot/global-acls imap(d2): Debug: acl: acl username = d2 imap(d2): Debug: acl: owner = 0 imap(d2): Debug: acl vfile: Global ACL legacy directory: /etc/dovecot/global-acls imap(d2): Debug: pub: Mailbox opened because: EXAMINE imap(d2): Debug: acl vfile: file /etc/dovecot/global-acls//.DEFAULT not found imap(d2): Debug: acl vfile: file /var/mail/pub/dovecot-acl not found see it's looking for: /etc/dovecot/global-acls//.DEFAULT instead of /etc/dovecot/global-acls/pub/.DEFAULT Checking with documentation https://wiki.dovecot.org/ACL it seems that prefix should still be part of the path, as it was before: """The filenames must start with namespace prefix (if it has one). For example with namespace prefix=INBOX/ containing mailbox "foo" use /etc/dovecot/acls/INBOX/foo.""" Just for comparison, previous version (2.2.10) would work fine: imap(d2): Debug: Namespace : type=public, prefix=pub/, sep=/, inbox=no, hidden=no, list=yes, subscriptions=yes location=maildir:/var/mail/pub imap(d2): Debug: maildir++: root=/var/mail/pub, index=, indexpvt=, control=, inbox=, alt= imap(d2): Debug: acl: initializing backend with data: vfile:/etc/dovecot/global-acls imap(d2): Debug: acl: acl username = d2 imap(d2): Debug: acl: owner = 0 imap(d2): Debug: acl vfile: Global ACL directory: /etc/dovecot/global-acls imap(d2): Debug: acl vfile: reading file /etc/dovecot/global-acls/pub/.DEFAULT imap(d2): Debug: acl vfile: file /var/mail/pub/dovecot-acl not found I've localized problem to: src/plugins/acl/acl-backend-vfile.c: acl_backend_vfile_object_init(...) and change from: vname = mailbox_list_get_vname(_backend->list, name); to: vname = *name == '\0' ? "" : mailbox_list_get_vname(_backend->list, name); that happened quite time ago during bigger acl changes and I don't know why exactly this line was changed previously. Anyway, reverting this line alone fixes the problem and while testing both per-mailbox ACL vfile and Global ACL file, reverting this did not affect them.

CVE-2019-7524 backport patch for 2.2.33.2
by Gerald Galster 28 Mar '19

28 Mar '19

Hello Aki, I'm currently stuck with 2.2.33.2 as 2.2.36 still duplicates mails after pop3 deletion on a two node dsync cluster. Therefore I've created a small patch and it seems only these two files are affected: dovecot-2.2.36.3/src/lib-storage/index/index-pop3-uidl.c dovecot-2.2.36.3/src/plugins/fts/fts-api.c Please correct me if I have missed something. Best regards Gerald

CVE-2019-7524: Buffer overflow when reading extension header from dovecot index files
by Aki Tuomi 28 Mar '19

28 Mar '19

Product: Dovecot Vendor: OX Software GmbH Internal reference: DOV-2964 (Bug ID) Vulnerability type: CWE-120 Vulnerable version: 2.0.14 - 2.3.5 Vulnerable component: fts, pop3-uidl-plugin Report confidence: Confirmed Researcher credits: Found in internal testing Solution status: Fixed by Vendor Fixed version: 2.3.5.1, 2.2.36.3 Vendor notification: 2019-02-05 Solution date: 2019-03-21 Public disclosure: 2019-03-28 CVE reference: CVE-2019-7524 CVSS: 3.0/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H/E:P/RL:O/RC:C (8.8) Vulnerability Details: When reading FTS or POP3-UIDL header from dovecot index, the input buffer size is not bound, and data is copied to target structure causing stack overflow. Risk: This can be used for local root privilege escalation or executing arbitrary code in dovecot process context. This requires ability to directly modify dovecot indexes. Steps to reproduce: Produce dovecot.index.log entry that creates an FTS header which has more than 12 bytes of data. Trigger dovecot indexer-worker or run doveadm index. Dovecot will crash. Mitigations: Since 2.3.0 dovecot has been compiled with stack smash protection, ASLR, read-only GOT tables and other techniques that make exploiting this bug much harder. Solution: Operators should update to the latest Patch Release. The only workaround is to disable FTS and pop3-uidl plugin. -- Aki Tuomi Open-Xchange Oy

dovecot mailing list stopped delivering mail
by Christian Anthon 28 Mar '19

28 Mar '19

Strangest thing. Since some time Marts 25. I'm no longer receiving mails from the dovecot mailing list server. Mails from other sources are behaving fine. Instead I'm just seing Mar 26 08:27:54 dna01 postfix/smtpd[107746]: Anonymous TLS connection established from talvi.dovecot.org[94.237.25.159]: TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits) Mar 26 08:27:54 dna01 postfix/smtpd[107746]: disconnect from talvi.dovecot.org[94.237.25.159] ehlo=1 starttls=1 quit=1 commands=3 And then no more. I tried turning up the postfix verbosity, but I'm none the wiser. I realize that this is probably not a dovecot issue, but anybody with any ideas?
