It's been made clear to me now that I need to look closer at greylisting in postfix before mails are passed to the proxy_filter. But if you're interested I'm talking around 62k mails a day. My experience with this amount has led me to use 64G RAM on each MX but that's only to handle a certain incident with very high load. Usually RAM usage is much lower than 64G and there's plenty of IO cache available. |
