these are smtp processes, mta clients, sending to port 25's. what about disk i/o? errors in maillog, dmesg, syslog messages if postfix is hurting, it usually logs it somewhere. tcp 0 1 209.113.151.5:4787 24.226.1.21:25 SYN_SENT >tcp 0 1 209.113.151.5:4786 69.60.142.31:25 SYN_SENT >tcp 0 1 209.113.151.5:4784 205.134.161.95:25 SYN_SENT how postfix smtpd and smtp processes are running? max? top shows what is using the cpu, memory? is it swapping itself to death?
