Hi John,
To warm IPs, instead of sending high volumes slowly (yeah, 20K per IP isn't
"high", but it might be too high anyway), you'd better send a small volume
per day, for several days.
If you have another pool already warm, you should use cold-virtual-mta in
some of the warm IPs in order to warm the cold IPs. By default,
cold-virtual-mta would take the 1000 first messages of each domain from the
warm vmta, and re-route them by the cold vmta. That makes 1000 @hotmail.com,
1000 @outlook.com, etc., that's enough for a warming.
Warming IPs at hotmail could take a few weeks, and of course depends on the
quality of the traffic, the number of complaints and traps you hit, etc.
You know your IPs are warm when they turn green in SNDS.
Hop that helps,
Benjamin
