+A lookup expansion is also available. It takes an email
+address as the key and an IP address as the database:
+
+ $lookup (username@domain} spf {ip.ip.ip.ip}}
+
+The lookup will return the same result strings as they can appear in
+$spf_result (pass,fail,softfail,neutral,none,err_perm,err_temp).
+Currently, only IPv4 addresses are supported.

-SMTPUTF8

+SMTPUTF8
Internationalised mail name handling.
RFCs 6530, 6533, 5890
- DSN unitext handling is not present
- 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.

+DSN extra information
+---------------------
+If compiled with EXPERIMENTAL_DSN_INFO extra information will be added
+to DSN fail messages ("bounces"), when available. The intent is to aid
+tracing of specific failing messages, when presented with a "bounce"
+complaint and needing to search logs.
+
+
+The remote MTA IP address, with port number if nonstandard.
+Example:
+ Remote-MTA: X-ip; [127.0.0.1]:587
+Rationale:
+ Several addresses may correspond to the (already available)
+ dns name for the remote MTA.
+
+The remote MTA connect-time greeting.
+Example:
+ X-Remote-MTA-smtp-greeting: X-str; 220 the.local.host.name ESMTP Exim x.yz Tue, 2 Mar 1999 09:44:33 +0000
+Rationale:
+ This string sometimes presents the remote MTA's idea of its
+ own name, and sometimes identifies the MTA software.
+
+The remote MTA response to HELO or EHLO.
+Example:
+ X-Remote-MTA-helo-response: X-str; 250-the.local.host.name Hello localhost [127.0.0.1]
+Limitations:
+ Only the first line of a multiline response is recorded.
+Rationale:
+ This string sometimes presents the remote MTA's view of
+ the peer IP connecting to it.
+
+The reporting MTA detailed diagnostic.
+Example:
+ X-Exim-Diagnostic: X-str; SMTP error from remote mail server after RCPT TO:<d3@myhost.test.ex>: 550 hard error
+Rationale:
+ This string somtimes give extra information over the
+ existing (already available) Diagnostic-Code field.
+
+
+Note that non-RFC-documented field names and data types are used.
