Internationalized Email now supported by amavisd (SMTPUTF8, EAI, IDN)

[Mark Martinec]

To go hand-in-hand with the Postfix support for Internationalized Email,
the new version 2.10.0 of amavisd mail content filter was released
today.

So now that we have it covered at an MTA and at a content filter stages,
it's perhaps time to step up the heat on developers of mail clients
and IMAP servers, reminding them that RFC 6530 is now two and a half
years old, and that only 5.43 % of the world population are native
speakers of English (2007) according to Wikipedia/Nationalencyklopedin:

https://en.wikipedia.org/wiki/List_of_languages_by_number_of_native_speakers


Key new features:

- added support for Internationalized Email:
* RFC 6530 - Overview and Framework for Internationalized Email
* RFC 6531 - SMTP Extension for Internationalized Email (SMTPUTF8)
* RFC 6532 - Internationalized Email Headers
* RFC 6533 - Internationalized Delivery Status Notifications

This supports UTF-8 (EAI) in SMTP/LMTP sender addresses, recipient
addresses, and message header section. Feature parity with Postfix
version 2.12 (support introduced in development snapshot 20140715).

The SMTPUTF8 extension is supported by Gmail since 2014-08-05:

- added support for Internationalized Domain Names (IDN) according
to IDNA (RFC 5890, RFC 5891; RFC 3490);
