i have just rebuilt a proxy server in a school but now the internal mail server is no longer receiving mails from iside the school or outside, it sends them out ok.

i have these lines in my susefirewall2:

FW_DEV_INT="eth0"
FW_DEV_EXT="eth1"
FW_SERVICES_DMZ IP=""
FW_SERVICES_EXT_IP=""

FW_ROUTE="yes"
FW_MASQUERADE="yes"
FW_FORWARD_MASQ="0/0,10.0.0.19,tcp,25"
FW_ALLOW_FW_TRACEROUTE="YES"


The address of the mail server is 10.0.0.19

the prxy servers internal address is 10.0.0.1 on eth0
