Hi all, I used the Perfect Setup Ubuntu Dapper 6.06 howto install, and I'm having problems getting email to work on my machine. When following the install, I changed server1.example.com to foo.com (real domain name replaced with generic). Inside ISPConfig I set up another domain name, bar.com. Going to www.foo.com and www.bar.com via Firefox works just fine, but it's the email I'm having problems with. When I go under sites and into www.bar.com and go to add an email, I add it there successfully. If I go into /etc/local-host-names I see that bar.com is in there, and when I go to /etc/postfix/virtusertable I see that the email accounts I add are there. However, when I send an email to any account I have set up, I always get the same error message: Code: PERM_FAILURE: SMTP Error (state 9): 550 <[email protected] When I go into the ISPConfig Admin Panel, Under Server Settings, the VirtUserFile is /etc/postfix/virtusertable and the Sendmail CW is /etc/postfix/local-host-names. If there is any other information I can provide, please let me know. Thanks in advance.
