Just to clarify. I'm aware that I can get the size value out of
$message_size.
I'm currently experimenting with reducing the amount of greylisting
being performed. My logic is currently as follows:
1.) We only want to greylist spam zombies
2.) We'll greylist everything, with exceptions so we don't miss anything
3.) Spam zombie software doesn't use TLS, so don't greylist on encrypted
connections.
4.) Spam zombie software probably doesn't use stuff like the SIZE
service extension, so don't greylist hosts that use it.
Point 4 was what made the $smtp_command thing catch my attention. I was
going to log the $smtp_command to see what hosts were actually using the
SIZE extension and gather some stats.
