[Pkg-exim4-users] Direct messages to specific IP or SMTP server

[Jeffs]

Hello All,

I am new to Exim and could use some help.  I am trying to figure out how 
to direct outgoing messages to a particular IP address or smtp server.  
Assuming an email campaign has several smtp servers each with their own 
IP address at their disposal, how could Exim help in analyzing the email 
message parts/domain to direct this message to, for example, 
xxx.xxx.xxx.xxx and that message to, for example, yyy.yyy.yyy.yyy

Thank you.
