[exim] Different hostname for different IPs

Hi, all!

How can I configure Exim to use different hostname for the HELO with other
Server depending by the IP I use for this route?

Example: I have 3 routes, that use 3 different IPs.
Can I use 3 different Hostname for the HELO with the remote Servers?

Thanks
