The mailing list for listmasters using Sympa

[Umut Arus <address@concealed>]

Hi,

I want to manage two domain name as smtpserver.domain.com, postfix (A) 
and list.domain.com, sympa (CNAME) on one server. First domain should be 
only "smtp", other domain should be "list".  In this case, sending 
message which both of domain are accepted and delivery messages but it 
have not to accepted for sympa by smtpserver.

I want use first IP as smtp and other as list serv.

Note: I had tested virtual domains and any way etc... Is there any 
suggestion to split these jobs?

regards,
