I have tried to set up Bubba to work with multiple domains - e.g. abc.co.uk and cba.co.uk and cba.com
I have entered these into the 'Received' page on the Bubba admin with a space inbetween each as suggested.
I am getting the following error when trying to reload postfix:
Please helpbubba:/home/gison# postfix reload
postfix: warning: valid_hostname: invalid character 32(decimal): bubba.abc.co.uk cba.co.uk cba.com
postfix: fatal: file /etc/postfix/main.cf: parameter myhostname: bad parameter value: bubba.abc.co.uk cba.co.uk cba.com

Thanks,
Graeme
