Quite the reverse of shared-IP virtual hosting!
You are not only in a good position to have Exim use the appropriate HELO for
each IP, you *should* do so. Optionally the smtp 'banner' and certs as well.
You can do this with a separate configuration per-IP invoking a 'listener'
daemon for each, or all within one, or on groups of 'n', even - this by use of
the '$interface' and 'helo_data' tools with conditionals, etc.
There are pros and cons to each approach - what you do with the queue(s), for
example.
There are examples in the list archives.
