Hi everyone. I installed ISPConfig3 yesterday on Ubuntu 11.04 64 bit. So far everything is working except that I cannot connect to the smtp server to send emails. I can receive emails and I can send emails throught squirrelmail. When I try to send emails via Mac Mail application or on iPhone, I cannot connect to the smtp server. I have used as url the FQDN of my server and as username I used my email address and the password of my emailaddress. What am I doing wrong?
