My mail server (BT Yahoo) connects to my system with test message, but I cannot persade it to send/receive emails because of 'port or SSL' problems. It the problem was not cured by switching off my firewall (NIS 2006). My notebook connects quite happily with all the same settings via the same broadband router. My wife's laptop works fine too (and she has NIS 2004 firewall active).
I have told the firewall to allow POrts 25 and 110 to accept traffic to no avail. There is nothing on the Symantec site that helps. I have run viruscan and spyware doctor and have found no infections so far.
Many thanks in advance for some advice to help me.
