Our ISP (Telstra bigpond) is closing port 25. I am on a dynamically assigned ADSL range which will have port 25 shut down. So I will need to move my home mail server to an unaffected IP range http://bigpond.custhelp.com/cgi-bin/bigpond.cfg/php/enduser/std_adp.php?p_faqid=5562 If any list members ISP has done this has it caused any unforseen issues?
