Hi bill. not sure what you want me to look there. The Cobalt will go away and will probably be used in other task. We are not trying to rescue it.

Have you looked at the BlueQuartz project? It is specifically for the Cobalts, and I think is CentOS based.

Hi, I have a customer with a sun cobalt running Sendmail 8.10.2/8.10.2 and we are phasing out the sun cube due to some limitations. So we have installed a new centos 5.x server. the format of our current emails are username@domain.com and the new format will be name.lastname@domain.com. We have 1600 accounts.

Both server are in the LAN.

The MX record that the world sees, point to our current AV/AntiSpam appliance, then our AV appliance forwards to the mail server (its a trendmicro IMSS) The AV appliance lets me define rules that emails for username@domain.com should be sent to the mailserver with the cube, and it also let me define a rule for name.lastname@domain.com to be sent to the centos machine, so I have covered the "from internet" inbound email issue. going out to the internet, both servers can send emails perfectly.

However, Since both servers will "answer" to the same domain, i need some guidance as to how to 1- If user hosted on the Sun sendmail Cube sends emails to name.lastname@domain.com, make the Cube forward/send the email to the Centos machine. 2- If user hosted in centos, sends email to username@domain.com, make the POSTFIX forward/send the email to the Cube machine.

Due to internal regulations i must say that: 1- users cannot be moved all at once. 2- centos machine must use postfix - not sendmail. I can however, install sendmail on centos and make it listen in another port other than 25 if some solution arises that needs sendmail in both sides.

Anyways, any guidance as to how to solve this mess is welcomed!!!!

Thanks,

for the postfix side, use transport_maps:

username@domain.com relay:[remote.host.example] (use the brakets to avoid MX lookups).

i read about transport maps in postfix, just tried and worked perfectly. thanks, now i have to figure the sendmail part (i think virtusertable)

Do you know how to make the sendmail part?

If you are already accepting for the domain in question, all you need are aliases. Just be careful you don't set up a loop as you move people.
