I have to move smarthost-B into a different network with different IPs Is there a way to "warm up" the IP-reputation of smarthost-B by starting with e.g. a 90:10 distribution and increase that over the time ?Just a guess (untested) - have you tried sth like hosts = A : A : A : A :A : A : A : A : A : B
This was also my first wild guess, but I thought Exim is too
intelligent for this simple aproach.
But indeed it works !
So, no sophisticated math is necessary, just a line like
hosts = A : A : A : A : A : A : A : A : A : B
and then reducing the number of A's over the time.
