Hi, I have received an attack to my pop3 server qpopper leading this to crash, and every time I woke up it crashed again. Eventually I filtered the attacker ip with iptables. The attacker was trying to login with usual names with many attempts per second (AKA brute force). After the attack I'm not very confident to qpooper, so is there any good alternatives to qpopper? what about xmail? Thank you Carlos.
