New Features in Exim
--------------------
go while a single connection is being processed. When a child process
terminates, the daemon decrements the variable.
+ 6. There's a new control called no_pipelining, which does what its name
+ suggests. It turns off the advertising of the PIPELINING extension to SMTP.
+ To be useful, this control must be obeyed before Exim sends its response to
+ an EHLO command. Therefore, it should normally appear in an ACL controlled
+ by acl_smtp_connect or acl_smtp_helo.
+
+ 7. There are two new variables called $sending_ip_address and $sending_port.
+ These are set whenever an SMTP connection to another host has been set up,
+ and they contain the IP address and port of the local interface that is
+ being used. They are of interest only on hosts that have more than on IP
+ address that want to take on different personalities depending on which one
+ is being used.
+
+ 8. The expansion of the helo_data option in the smtp transport now happens
+ after the connection to the server has been made. This means that it can
+ use the value of $sending_ip_address (see 7 above) to vary the text of the
+ message. For example, if you want the string that is used for helo_data to
+ be obtained by a DNS lookup of the interface address, you could use this:
+
+ helo_data = ${lookup dnsdb{ptr=$sending_ip_address}{$value}\
+ {$primary_hostname}}
+
+ The use of helo_data applies both to sending messages and when doing
+ callouts.
+
+ 9. There is a new expansion operator ${rfc2047d: that decodes strings that
+ are encoded as per RFC 2047. Binary zero bytes are replaced by question
+ marks. Characters are converted into the character set defined by
+ headers_charset. Overlong RFC 2047 "words" are not recognized unless
+ check_rfc2047_length is set false.
