Just to say that I followed the multiserver setup guide on the ISPConfig manual and ISPConfig works great!
I am however having problems with email. I have seen where I went wrong with the squirrelmail config - use dovecot instead of courier.
I have setup a new domain and mail box in ISPConfig, I can login to squirrelmail, but cannot send or recieve emails. I get the error :
Message not sent. Server replied:
554 5.7.1 <email@example.com>: Relay access denied
Any ideas?, Thanks very much!.
