From the attached log:

newaliases: fatal: myorigin parameter setting must not contain multiple values: ,amkcambodia.com

I have reproduced this. It is a problem with debconf input validation: a comma should not be allowed in debconf fields postfix/mailname or postfix/destinations.

Borin: purge postfix and try again, taking care not to put a comma in your answer to "System mail name".

However I'm leaving this bug open to fix the debconf input validation.

Workaround:

dpkg -P postfix
apt-get install postfix
(and revise mail name)
