Status of SMTPUTF8?
by Noah Tilton 14 Sep '18

14 Sep '18

I was wondering whether there is a roadmap for adding SMTPUTF8 support to Dovecot? My delivery pattern is Postfix -> Dovecot LMTP and it is choking on utf8 messages. I might be able to volunteer some of my time as a developer. Another thread about this seemed to go unanswered: http://dovecot.org/list/dovecot/2016-September/105474.html http://unix.stackexchange.com/questions/320091/configure-postfix-and-doveco… -Noah

LMTP tcp listener with auth?
by Andreas Thienemann 13 Sep '18

13 Sep '18

I am wondering if it's possible to have a tcp listener for LMTP do authentication and not accept any unauthenticated mail. My configuration looks like the following: service lmtp { inet_listener lmtp { address = 192.168.0.1 127.0.0.1 port = 24 } } This gives me a network reachable lmtp socket, but of course no autentication. When reading the docs, it seems though that only userdb lookup and no actual authentication is supported? Is that understanding correct? cheers, Andreas

Server certificate verification error with Dovecot 2.3.2.1
by Robert Gill 13 Sep '18

13 Sep '18

I'm attempting to upgrade my Dovecot installation to 2.3.2.1. My SSL certificate authority provides a bundle containing their CA, plus intermediate CAs, which I configure using the 'ssl_ca' option. The comments in the configuration file say to only set this when you're requiring client certificates, which I'm not, but fetchmail complains with a "Server certificate verification error, Broken certificate chain" error if that setting is not set. This works fine with Dovecot 2.2.34. After upgrading to 2.3.2.1, fetchmail throws that error whether 'ssl_ca' is set or not. Dovecot 2.3.2.1 reports the error SSL routines:ssl3_read_bytes:tlsv1 alert unknown ca: SSL alert number 48 in the logs when attempting the TLS handshake. The permissions on the CA bundle haven't changed and should still be readable by Dovecot. I'm running Gentoo Linux on x86_64 and mail is stored on an ext4 file system. I'm attaching my config files for both Dovecot 2.2.34 and Dovecot 2.3.2.1.

dovecot + centos 7 + internal ca + hostname change
by Matt Bryant 13 Sep '18

13 Sep '18

Not sure if this is dovecot or not but can find very little ie no info around on this ... and added the pem file into /etc/pki/ca-trust/source/anchors and run udpate-ca-trust .. all works ok .. (this is on centos 7 btw) So wanted to change the hostname away from ip-x-x-x-x to something a little bit more descriptive .. but then kaboom .. doesnt work any more and the following errors are seen. Have created and internal CA for domain and added it to Sep 13 10:42:04 ip-10-0-40-230 dovecot: master: Dovecot v2.2.33.2 (d6601f4ec) starting up for imap, pop3, lmtp, sieve (core dumps disabled) Sep 13 10:42:04 ip-10-0-40-230 dovecot: auth: Error: p11-kit: 'attr->pValue != NULL' not true at attrs_build Sep 13 10:42:04 ip-10-0-40-230 dovecot: auth: Error: p11-kit: 'lexer->tok.field.name && lexer->tok.field.value' not true at p11_lexer_next Sep 13 10:42:04 ip-10-0-40-230 dovecot: auth: Error: p11-kit: 'attrs != NULL' not true at attrs_build Sep 13 10:42:04 ip-10-0-40-230 dovecot: message repeated 16 times: [ auth: Error: p11-kit: 'attrs != NULL' not true at attrs_build] Sep 13 10:42:04 ip-10-0-40-230 dovecot: auth: Error: p11-kit: 'new_memory != NULL' not true at maybe_expand_array Sep 13 10:42:04 ip-10-0-40-230 dovecot: auth: Error: p11-kit: shouldn't be reached at p11_array_push Sep 13 10:42:04 ip-10-0-40-230 dovecot: auth: Error: p11-kit: shouldn't be reached at sink_object Sep 13 10:42:04 ip-10-0-40-230 dovecot: auth: Error: p11-kit: 'attrs != NULL' not true at attrs_build Sep 13 10:42:04 ip-10-0-40-230 dovecot: auth: Error: p11-kit: 'new_memory != NULL' not true at maybe_expand_array Sep 13 10:42:04 ip-10-0-40-230 dovecot: auth: Error: p11-kit: shouldn't be reached at p11_array_push Sep 13 10:42:04 ip-10-0-40-230 dovecot: auth: Error: p11-kit: shouldn't be reached at sink_object ... ...

Adding namespace alias_for causes index resync?
by Tom Sommer 12 Sep '18

12 Sep '18

I just added a new namespace-alias with alias_for. Apparently this causes all mailbox indexes to be resynced? Is this intentional and/or is there some way to avoid this? My NFS storage pretty much kills its elf when hundreds of thausands of users needs to resync indexes :) Thanks -- Tom

Hi Stephan, On Wed, 12 Sep 2018, Stephan Bosch wrote: > LMTP currently does not support AUTH. Bummer. Thought so. > What is your use case? Most people hide LMTP behind a firewall, or don't > expose it through TCP/IP in the first place. The port is currently only available to a few trusted machines, but having auth available would have been a nice benefit in case the firewall gets misconfigured. Cyrus for example will expose the LMTP port via TCP if configured, but expects valid user credentials. The larger use-case is a migration from cyrus to dovecot. As it's not just the MDA but also the MTA installation that is being migrated I need a way to deliver mail from the old MTA to the new MDA. LMTP comes in handy. https://github.com/ixs/lmtp_proxy/blob/master/README.md#minmal-downtime-mig… has a rough invocation of the steps needed for that. As I said, LMTP auth isn't critical for this, but would have been a nice addition. cheers, Andreas
