Hi,

Dovecot 2.4 was released today. The binary packages and docker images they’ve built have L1 support/silver level support, if one enables mail_utf8_extensions in the configuration file. It’s disabled by default in this version.

I timidly guess that if they don’t get many bug reports related to mail_utf8_extensions, then a future version will enable it by default. I am happy for now: Progress is progress, more is luxury.

The open source servers with support are now Dovecot, Courier, Wild Duck and Stalwart IIRC. The ones missing support are Cyrus, those that build on Cyrus (mostly commercial/integrated offers) and a few rather minor servers. I have a compliant version of Cyrus running and have passed the changes to the head maintainer. He and I will meet in March, so I feel good about progress on that front.

At some point in the next six months I think it will be simple for mail client authors to test EAI support, because at least one server in their testing setup will already have support.
