ok this is very weird

from outlook and from telnet through (ssh)
it gives no errors, but does not send


but from netcat(which looks the same as telnet)
it gives
554 5.7.1 <xxxxxxxxxxx@hotmail.com>: Relay access denied


either way this new configuration has the same end goal of not being able to send.... just the error reporting method is different

The most likely reason for that error is the ISP that hosts your server is blocking outbound connections on port 25. I'm guessing you're using a residential style internet connection, which is why you are using dyndns. It's common for ISPs to block port 25 outbound from those kinds of connections to help stop spam from zombied home computers.

Possibly, it may be your own firewall preventing outbound connections on port 25, but most allow all outbound connections by default. Either way, your problem is related to firewalling.

just called my ISP and they said that there was no blocking and its definately not my home router ....

i found this on the internet:
"Note : If you install Postfix/Dovecot mail server you will ONLY be able to send mail within your network. You can only send mail externally if you install SASL authentication with TLS. As otherwise you get “Relay Access Denied” error."

im gonna give this a try in the next couple hours ill let you know how it goes

From the information you've given, I suspect your server is on a Bigpond connection. They definitely do block port 25 outbound on most connections.

I meant to add that if you find out the name of your ISP's mail server, you can just set postfix to send mail out through it to bypass the block. In /etc/postfix/main.cf, either edit or create the line

relayhost = my.isp.mailserver.net

and restart postfix.

Please check if you're blacklisted: http://mxtoolbox.com/blacklists.aspx

If you have a dynamic IP, you will have to set up relaying: http://www.howtoforge.com/postfix_re...her_mailserver

matty was right

my port is blocked by bigpond (who are now my least favourite ISP)

i am on one black list, sorbs-duhl .... only because my ip is dynamic

i used the ping smtp tool on mxtoolbox.com and i got no reply, even though i can still recieve emails,

i think the problem is definately blocked port

im changing my internet connection very soon and this should solve the problem

thank you very much guys, problem well solved
