Hi ,
You should should find the mail handler of the domain
"hotmail.com". You may get the answer from your DNS server as following:
; <<>> DiG 9.6.-ESV-R3 <<>> @8.8.8.8 hotmail.com mx
; (1 server found)
;; global options: +cmd
;; Got answer:

After doing this, you could choose one of them and try to telnet the
smtp port at the host you picked. For example, if you try to telnet
the smtp port at mx1.hotmail.com, you may get the greeting message as
following:
Trying 65.55.92.184...
Connected to mx1.hotmail.com.
Escape character is '^]'.
220 SNT0-MC4-F13.Snt0.hotmail.com Sending unsolicited commercial or
bulk e-mail to Microsoft's computer network is prohibited. Other

Please do not try to telnet "hotmail.com", it may not set to forward
your request to the mail handler. Thanks!

No route to host means your IP cannot reach the remote IP, not port
related. Check your IP/gateway/subnet mask settings, and try `nslookup
hotmail.com` and `traceroute hotmail.com`

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?

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.
