Postfix Virtual Domain Hosting

Braucht man immer wieder mal,

/etc/postfix/main.cf:
virtual_alias_domains = example.com ...other hosted domains...
virtual_alias_maps = hash:/etc/postfix/virtual

/etc/postfix/virtual:
postmaster@example.com postmaster
info@example.com       joe
sales@example.com      jane
# Uncomment entry below to implement a catch-all address
# @example.com         jim
...virtual aliases for more domains...

postmap /etc/postfix/virtual
/etc/init.d/postfix reload

findet man alles gut erklaert unter http://www.postfix.org/VIRTUAL_README.html
