New Features in Exim
--------------------
in the presence of multiple character strings within the RR. Prior to 4.70,
only the first string would be returned. The dnsdb lookup now, by default,
preserves the pre-4.70 semantics, but also now takes an extended output
- separator specification. The first output separator is used to join
- multiple TXT records together; use a second separator character, followed
- by a colon, to join the strings within a TXT record on that second
- character, or use a semicolon to concatenate strings within a TXT record
- with no separator. Administrators are reminded that DNS provides no
- ordering guarantees between multiple records in an RRset. For example:
+ separator specification. The separator can be followed by a semicolon, to
+ concatenate the individual text strings together with no join character,
+ or by a comma and a second separator character, in which case the text
+ strings within a TXT record are joined on that second character.
+ Administrators are reminded that DNS provides no ordering guarantees
+ between multiple records in an RRset. For example:
foo.example. IN TXT "a" "b" "c"
foo.example. IN TXT "d" "e" "f"
${lookup dnsdb{>/ txt=foo.example}} -> "a/d"
${lookup dnsdb{>/; txt=foo.example}} -> "def/abc"
- ${lookup dnsdb{>/+: txt=foo.example}} -> "a+b+c/d+e+f"
+ ${lookup dnsdb{>/,+ txt=foo.example}} -> "a+b+c/d+e+f"
- Some character combinations are currently unsupported.
Version 4.70 / 4.71
-------------------
1. Native DKIM support without an external library.
+ (Note that if no action to prevent it is taken, a straight upgrade will
+ result in DKIM verification of all signed incoming emails. See spec
+ for details on conditionally disabling)
2. Experimental DCC support via dccifd (contributed by Wolfgang Breyha).
