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.
