Hi people:
I feel in need to receive advice from you.
My main experience came from sendmail on Solaris 10 and Solaris 11.
We have this site with Solaris, CentOS, Ubuntu and Windows (with SMTP service)
servers.
At first, every server was a SMTP server, but now we want that every box send
email to a pair of postfix servers as mailhubs. Our localsite mailhubs are
running postfix 2.9.4 on Solaris 10 for X86 (right now I'm planning the
migration over CentOS with postfix).
So far I have been able to setup this config but; my problem arises when I need
to expand some aliases; this aliases point to local users on some servers and
the main mailhubs (corporate) that runs Windows Exchange.
I want to process the alias at our mailhubs since they are only two instead 55
servers and I don't have access to the Corporate Mailhubs.
So my setup is like
My site servers-------------------> Our Mailhubs ---------> Corporate
Mailhubs--->realusers@domain
Cases
1) there is an alias on the local mailhubs
{ alias1 -->
finaluser@domain,someuser@mysite-server }
dbauser@domain ---------------> alias1 -------------------> Corporate Mailhubs
--> finalrealuser@domain
^ \--------------->someuser@mysite-server \
\
|
\ ----------------------------------------------------------/
2) there isn't an alias on local mailhubs
dbauser@domain ---------------> no alias -------------------> Corporate
Mailhubs --> finalrealuser@domain
As I told you, my idea is make an easier setup where the future admins just
modify the alias instead setup that alias on every localsite server.
So my request is some advice to accomplish this task with much hassle.
On networks file I have my ip address blocks
On aliases file I have for emails to soapbd@domain
soapbd:finalrealuser@domain,soapbd@mysite-server
on transport file
* smtp:smtpapl.domain
On main.cf
mynetworks = $config_directory/mynetworks
transport_maps = hash:/etc/opt/csw/postfix/transport
Any help or tutorial really appreciate.
