Hello all, Again a problem with my server. The situation is like this: I have setup my own server here at home. Its in my home network. I used the perfect setup with Ubuntu 7.10. I have setup an domain for our band with email users. I CAN sent and receive email without any problems all is working fine. So postfix is running nicely for me in my network at home. However if any of the other band members are trying to use their email, outside of my network, they can receive email but they cant sent any out. I have tryed it my self from outside my network and indeed its not sending emails out. I am getting the following error (in dutch) Code: Het maken van een verbinding met de server is mislukt. Account `www.dcs-online.nl`server`www.dcs-online.nl`protocol (:SMTP,poort : 25,beveiligd (ssl):nee, socketsfout,10060 foutnummer x800cccoe Rougly translated Code: cannot connect to server. Account `www.dcs-online.nl`server`www.dcs-online.nl`protocol (:SMTP,poort : 25,secured (ssl):NO, socketsfout,10060 foutnummer x800cccoe Yes authenticate smtp is enabled in outlook express. And is using the same as pop3. Must I forward some other ports in my router? I have forwarded the following 80, 81, 25, 2525, 110, 20 and 21 I am confused can someone point to the solution please.
