Hi,
I am currently using exim and was doing and installation on postifx. I
needed postfix to accept mail for domain.com <http://domain.com> and
deliver the email to 2 different servers a local and remote without
configuring forwarders. We have implemented this in exim but would like
to do the same with Postfix.
Can someone shed some light on how to configure this? If you have a
better way to achieve the same thing without the use of forwarders I'm
open to suggestions.

To send mail to an additional destination, you need to add an
additional recipient. Use virtual_alias_maps to add a second
recipient, transport_maps to direct the mail where it should
go, and smtp_generic_maps to rewrite the address back to the
original form as it's transmitted.
A basic example:
main.cf:
virtual_alias_maps = hash:/etc/postfix/virtual
virtual:
[email protected] [email protected] [email protected]
Then use a transport table entry to route the new mail to the
proper server.
main.cf:
transport_maps = hash:/etc/postfix/transport
transport:
new.example.com relay:[192.168.192.168]
Then use a pcre smtp_generic_maps to rewrite the recipient
back to the original domain when postfix sends the mail.
main.cf:
smtp_generic_maps = pcre:/etc/postfix/smtp_generic.pcre
smtp_generic.pcre:
/^(.*)@new\.example\.com$/ [email protected]
Important Notes:
Do not change your current setting for virtual_alias_domains.
Do not use wildcard or regexp rewrites in virtual_alias_maps;
each recipient must be listed individually.
