I’m only a casual user. I wanted to begin experimenting with internationalised email envelopes, but I now realise that support is poor and interest is low throughout the email universe.
Dovecot alternatives with good i18n support?
Hello! I’m interested in exploring alternative IMAP servers that have good support for internationalised email, such as support for SMTPUTF8, IDN mail domains, Unicode local-part, etc. etc. If you used to use Dovecot, and found an alternative that does such things well, I would very much like to hear it. Thank you, -- David
Still interested in SMTPUTF8 support
I haven’t seen this term on the mailing list for a while. I don’t know if you’re tracking this somewhere, in any case I’m curious if you are still planning to add support for SMTPUTF8. Cheers,
Re: SMTPUTF8 support
I’m afraid there is a possibility that your setup only works by chance … I don’t think Dovecot LMTP is SMTPUTF8-capable according to RFC 6531. It needs to advertise the SMTPUTF8 extension but doesn’t. # nc -U /var/spool/postfix/private/dovecot-lmtp 220 mail.my.org Dovecot ready. LHLO mail.my.org 250-mail.my.org 250-STARTTLS 250-8BITMIME 250-ENHANCEDSTATUSCODES 250 PIPELINING -- David
Re: SMTPUTF8 support
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
