i've just setup redhat ES4 and everything seems to be working fine except the email.
I know that the email is working coz i can send out email but i just cant recieve any emails.. i've setup all the mx records.. dns etc.
I have a feeling its something to do with the firewall. I have configured my netgear dsl router to forward all requests on port 25 to my linux server. I've always allowed smtp requests on the redhat firewall but i still cannot recieve any email.
Is there any way i can do some tests to see if any messages reach the machine??
thanks..
Code:
netstat -an | grep :25 | grep tcp
tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN
