Sorry for asking everything but I want to make sure there isn't any rejection.
I run the command you told me. To my weak understanding ther is no
restrictions at all in the iptables isn't it?--------------
root@xn--hadibakalm-5ub:~# iptables -L -nChain INPUT (policy ACCEPT)target
prot opt source destination
Chain FORWARD (policy ACCEPT)target prot opt source
destination
Chain OUTPUT (policy ACCEPT)target prot opt source
destination

Hi there, I asked to my ISP to open port 25 but they insisted on that they
are not blocking any of my ports. But still the below command outputs "no
route to host" error message.
#telnet hotmail.com 25
On the other hand to make sure I am not blocking any outgoing port myself,
I installed firestarter program and selected the "allow everything except
selected ports" option then blocked nothing. I hope this will allow any
outgoing ports to be opened.
This is very weird that the mail server send mail when relayed from any
machine except the localhost itself. On debian how can I send mail with php any
suggestion would be apprecriated.
