Hello all,
thanks to everybody who has replied to my email !
Yes, my sole concern is actually the performance of my pop server when my pop3 users base getting larger.
But I think with a E250/220 running having 2 CPUs , 1MB of RAM, around 200GB HD I should be able to handle up to 20000 pop3 users easily, shouldn't I ?
Roeland, you mentioned in your email about XTND XMIT, may I know what is that ?
And about HA for Qpopper, are you saying that you have HA agent for Qpopper ?
thanks,
Muljawan
