I need to let smtp traffic through our pix - our exchange 2003 server can receive email but not send. I have checked over the config and think it has to be a firewall issue. We are trying to relay through our ISP's smarthost (smtp.easynet.co.uk), but no email is being sent. I cannot telnet to the address from inside our network on port 25, but I can OK from a PC outside the network, which leads me to suspect the firewall config. I have added the following commands and saved them to memory, but it still doesnt work:
static (inside,outside) 217.206.*.* 192.168.46.101 netmask 255.255.255.255 0 0
access-list inside permit tcp host 192.168.46.101 any eq smtp
i am running out of ideas, need a cisco guru to lend a hand!
