+SMTPUTF8
Internationalised mail name handling.
RFCs 6530, 6533, 5890
Helo names sent by the smtp transport will have any utf8
components expanded to a-label form.
+Any certificate name checks will be done using the a-label
+form of the name.
+
Log lines and Received-by: header lines will aquire a "utf8"
prefix on the protocol element, eg. utf8esmtp.
${utf8_localpart_to_alabel:str}
${utf8_localpart_from_alabel:str}
+New "control = utf8_downconvert" ACL modifier,
+sets a flag requiring that addresses are converted to
+a-label form before smtp delivery, for use in a
+Message Submission Agent context. Can also be
+phrased as "control = utf8_downconvert/1" and is
+mandatory. The flag defaults to zero and can be cleared
+by "control = utf8_downconvert/0". The value "-1"
+may also be used, to use a-label for only if the
+destination host does not support SMTPUTF8.
+
+If mua_wrapper is set, the utf8_downconvert control
+defaults to -1 (convert if needed).
+
+
+There is no explicit support for VRFY and EXPN.
+Configurations supporting these should inspect
+$smtp_command_argument for an SMTPUTF8 argument.
+
+There is no support for LMTP on Unix sockets.
+Using the "lmtp" protocol option on an smtp transport,
+for LMTP over TCP, should work as expected.
+
Known issues:
- - Currently LMTP is not supported.
- DSN unitext handling is not present
- - no provision for converting logging from UTF-8
- - VRFY and EXPN not handled
- - non-smtp input not handled (!)
- - MSA mode not handled (!)
+ - no provision for converting logging from or to UTF-8

+IMAP folder names
+
+New expansion operator:
+
+${imapfolder {<string>} {<sep>} {<specials>}}
+
+The string is converted from the charset specified by the headers charset
+command (in a filter file) or headers_charset global option, to the
+modified UTF-7 encoding specified by RFC 2060, with the following
+exception: All occurences of <sep> (which has to be a single character)
+are replaced with periods ("."), and all periods and slashes that aren't
+<sep> and are not in the <specials> string are BASE64 encoded.
+
+The third argument can be omitted, defaulting to an empty string.
+The second argument can be omitted, defaulting to "/".
+
+This is the encoding used by Courier for Maildir names on disk, and followed
+by many other IMAP servers.
+
+ Example 1: ${imapfolder {Foo/Bar}} yields "Foo.Bar".
+ Example 2: ${imapfolder {Foo/Bar}{.}{/}} yields "Foo&AC8-Bar".
+ Example 3: ${imapfolder {Räksmörgås}} yields "R&AOQ-ksm&APY-rg&AOU-s".
+
+Note that the source charset setting is vital, and also that characters
+must be representable in UTF-16.
