No problem. I explore a method to send images up to 1 billion light years (or more) in my article by drawing images from Dyson spheres on a galactic plane.
If your messages which take millions of years to arrive are relevant to a war, the war also goes on for millions of years. Why would you expect to see anything change over a mere century or so?
Intergalactic war may go for million of years. But humans now are naive civilization and the first who can affect it by ideas of a computer program will win it. Basically it would help to convert Earth in a remote fortress which will help to start colonization of our part of the universe. As a result, a territory of the message sender would grow .
Meh. For a war waged over millions of light years (and, necessarily, lasting millions of years) what can Earth offer? Some atoms? They are easily found elsewhere.

A new starting point to send probes with the half speed of light in all directions in the backland of the enemy.
Any star system will do for that purpose. All you need is star’s energy.
No, you need a traitor behind enemy lines to receive a message and start an attack. Star system without a civ can’t receive a message.
Ah, I see. You’re thinking, basically, about an information plague which, moving at c, leapfrogs physical probes.
See astronomer Fred Hoyle’s A For Andromeda for a fictional exploration of the idea (and a pretty good novel).
I was thinking more of Vernon Vinge’s A Fire Upon the Deep, but yeah, this is not a new idea.
Yes!
