Re: dovecot lmtp and smtputf8
Using the changes described in this pull request https://github.com/dovecot/core/pull/190, you can add SMTPUTF8 capability to the Dovecot LMTP server. Work on the patch is still in progress, and UTF8 support is not complete. However, you can use the following trick: Enable SMTPUTF8 support in Postfix, but make emails with UTF8 characters as aliases so that the final recipient doesn't have UTF8 characters. Even in this case, on the LMTP side, you need to announce the UTF8 capability, which will be possible if you apply the changes from the pull request. ___ dovecot mailing list -- dovecot@dovecot.org To unsubscribe send an email to dovecot-le...@dovecot.org

What is the relation between RFC 6531 and the DNS? I’m clearly no expert, but I thought that RFC only specified an SMTP extension. How are DNS servers concerned by that? Anyway, Postfix already implemented SMTPUTF8. Having Dovecot do as well would allow for mail-stack that rely on both Postfix and Dovecot to send e-mail using addresses containing non-ASCII characters. That would be a big progress for people who wish to use internationalized e-mail addresses. And the last time I asked questions about it here, people said to me it was being worked on.

I think you are confusing acceptance of UTF8 in the localpart of the email address (which if I remember correctly worked in the 2.2 branch) with SMTPUTF8 support. As mentioned in the thread above Dovecot does not as yet support SMTPUTF8. Support for SMTPUTF8 would mean among other things changing the source code of Dovecot so that it announces the SMTPUTF8 key word to the upstream MTA. John

Worse, it will create bounces on postfix accepted UTF8 localpart addresses as per https://www.dovecot.org/pipermail/dovecot/2019-March/115286.html This one is tracked as DOP-1045 as per Aki's email linked above. No idea when SMTPUTF8 will be implemented. It will create a big mess as Postfix with smtputf8=on defaults are being used _and_ people start using UTF8 localparts. Cf. http://www.postfix.org/COMPATIBILITY_README.html#smtputf8_enable for postfix info. You should configure a Postfix that delivers to Dovecot with smtputf8_enable=no until Dovecot learns SMTPUTF8. But even in such a defensive setup Dovecot LDA and LMTP can still create backscatter spam bounces as explained in the mailinglist thread linked above.

In this thread someone from Open-Xchange stated that no, Dovecot doesn’t have SMTPUTF8 support implemented, and the same response was given by another Dovecot developer last September (it ‘is being considered’ was the answer then, see https://dovecot.org/pipermail/dovecot/2018-September/112887.html). I am using LMTP to deliver mail to Dovecot from Postfix, and delivery fails with Postfix reporting: ‘SMTPUTF8 is required, but was not offered by host mail.my.org[private/dovecot-lmtp]’. I doubt that this can work without a change in Dovecot LMTP. Anyway, I am also interested in SMTPUTF8 support, so +1 from me! Hello David et al, I have it working with my set up, and I confirm it is not easy. If I limit the stack to OpenLDAP, Postfix and Dovecot to their simplest configuration, it is relatively easy, even with slightly outdated software in Debian Stretch. The trick I am using is to include the internationalised email address aside the main one, and to use Postfix LDAP lookup. For instance, I am using this LDAP schema: https://tools.ietf.org/html/draft-stroeder-mailboxrelatedobject-07 So, my LDAP lookup table for Postfix looks like this: # Basic LDAP settings for postfix server_host = ldap://ldap.rodier.me/ start_tls = yes search_base = dc=rodier,dc=me search_scope = sub # Allow advanced LDAP search with the recipient delimiter query_filter = (|(mail=%s)(intlMailAddr=%s)) result_attribute = mail # Force support for UTF8 version = 3 Therefore, postmap query works as expected: postmap -q andré@rodier.me ldap:/etc/postfix/ldap-aliases.cf an...@rodier.me That said, if only one of the milter reject your message, it is breaking the whole chain. For instance, the quota plugin for Dovecot, I had to use DUNNO when the user is unknown instead of reject. I have it working perfectly from Homebox to Homebox, so perhaps Postfix to Postfix, but I reckon I still have some bugs. Some providers are working, others not. Outlook does not seems to work , but I am on it. Yahoo does not let you type an accent in the email address, only Google allows you to. However, I made a test yesterday, and realised that the emails from GMail are rejected by one of the plugin, and I need to investigate which one. The error message is: Apr 5 10:16:39 portal postfix/smtpd[2566]: Anonymous TLS connection established from mail-lf1-f51.google.com[209.85.167.51]: TLSv1.2 with cipher ECDHE-RSA-AES128-GCM-SHA256 (128/128 bits) Apr 5 10:16:39 portal policyd-spf[2574]: prepend Received-SPF: Pass (mailfrom) identity=mailfrom; client-ip=209.85.167.51; helo=mail-lf1-f51.google.com; envelope-from=andre.rod...@gmail.com; receiver= Apr 5 10:16:39 portal postfix/smtpd[2566]: EB38240467: client=mail-lf1-f51.google.com[209.85.167.51] Apr 5 10:16:40 portal postfix/cleanup[2576]: EB38240467: message-id= Apr 5 10:16:40 portal opendkim[15477]: EB38240467: mail-lf1-f51.google.com [209.85.167.51] not internal Apr 5 10:16:40 portal opendkim[15477]: EB38240467: not authenticated Apr 5 10:16:40 portal opendkim[15477]: EB38240467: DKIM verification successful Apr 5 10:16:40 portal opendkim[15477]: EB38240467: s=20161025 d=gmail.com SSL Apr 5 10:16:40 portal opendmarc[16548]: implicit authentication service: portal.homebox.space Apr 5 10:16:40 portal opendmarc[16548]: EB38240467: gmail.com pass Apr 5 10:16:40 portal postfix/cleanup[2576]: EB38240467: milter-reject: END-OF-MESSAGE from mail-lf1-f51.google.com[209.85.167.51]: 4.7.1 Try again later; from= to= proto=ESMTP helo= Apr 5 10:16:40 portal postfix/smtpd[2566]: disconnect from mail-lf1-f51.google.com[209.85.167.51] ehlo=2 starttls=1 mail=1 rcpt=1 data=0/1 quit=1 commands=6/7 So perhaps it is one of the milter.

Well, what a puzzle. I will have to investigate. I also tried it with Gmail, and the failure was definitely between Postfix and Dovecot LMTP, with Dovecot failing to advertise SMTPUTF8 support. My setup is much more minimal, I use file-based virtual mailboxes and aliases, and only OpenDKIM and SpamAssassin milters. Thank you for your reply, André!

Re: SMTPUTF8 support
André, are you quite sure you have it working? In this thread someone from Open-Xchange stated that no, Dovecot doesn’t have SMTPUTF8 support implemented, and the same response was given by another Dovecot developer last September (it ‘is being considered’ was the answer then, see https://dovecot.org/pipermail/dovecot/2018-September/112887.html). I am using LMTP to deliver mail to Dovecot from Postfix, and delivery fails with Postfix reporting: ‘SMTPUTF8 is required, but was not offered by host mail.my.org[private/dovecot-lmtp]’. I doubt that this can work without a change in Dovecot LMTP. Anyway, I am also interested in SMTPUTF8 support, so +1 from me! -- David

SMTPUTF8 support
Hi, I'm currently trying to set up SMTPUTF8 on my mail stack, but I can't find any information on Dovecot's RFC 6531 support. Has it been implemented yet? If so, does anyone know how to activate it? Regards. -- Sylvhem

I had to reconfigure our MTAs to stop advertising SMTPUTF8 because after investigating complaints of missing mail, it turned out messages were making it all the way through every hop only to be rejected right at the mailbox (quite disappointing). Some senders will resend or send an alternate non-UTF8 message when SMTPUTF8 isn't advertised, but I still wonder how many messages are simply never sent because (a single component of) our mail system can't support it...

Re: Status of SMTPUTF8?
I necro-bump this thread as I have the same problem since I switched to LMTP from LDA (as the wiki recommend). Any news to make dovecot LMTP postix compliant ?

Dovecot lmtp support for SMTPUTF8
Hello, I'm using dovecot lmtp with Postfix. I'm enabling SMTPUTF8 (EAI), but when Postfix (v 3.1.2) tries to deliver the message to dovecot-lmtp it receive this error: status=bounced (SMTPUTF8 is required, but was not offered by host dlvmx.espsrv.net[private/dovecot-lmtp] I'm not sure if Dovecot lda and lmpt support EAI and how can I enable it. I've just found and old thread: http://www.dovecot.org/list/dovecot/2013-January/087756.html Thanks for your help. -- Igor Colombi
