Note that the OP is going to have something like 192.168.2.0/24 for dc_relay_nets. Even if exim was listening on an external interface (an empty dc_local_interfaces) exim is not set up to relay mail due to a connection on this interface. And then we have the bedtime stories to frighten the children: hordes of attempts to relay through a mail server. Like this one: 2014-10-06 07:19:44 H=114-43-21-85.dynamic.hinet.net (80.177.21.246) [114.43.21.85] F=<sdf2...@hotmail.com> rejected RCPT <sanjin...@yahoo.com.tw>: relay not permitted 2014-10-06 07:19:45 unexpected disconnection while reading SMTP command from 114-43-21-85.dynamic.hinet.net (80.177.21.246) [114.43.21.85] There is more chance of the 0's and 1's of my exim binary spontaneously disassociating and reassembling into a copy of postfix than one of these getting through. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
