The whole process is not so much about exim as farmore how the packet management works. (1) If you have your own configuration file in /etc/exim4/exim4.conf there will be no such problem. (2) If you have configured your Exim using the debian packet configuration there also would be no problem. (3) If you are running a modified configuration derived from the debian configuration there might be a glitch but this would be unlikely. > Can anybody recommend one of the approaches or even propose something > better...? - in case of (3) you also can: - prevent exim from starting: set "exit 0" as first line in /etc/default/exim4 - create a packet filter rule dropping connections to port 25/tcp - create /etc/exim4/exim4.conf which just makes exim return SMTP error 451 HTH -- Christian Recktenwald [email protected] -- ## List details at https://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
