Again I'm using postfix MTA. There are lots of
output when I enter the command grep aron /var/log/maillog. Do I have to
worry.
Aug 14 12:15:54 mail postfix/qmgr[733]: E0D9EAADD0:

output logs that keeps me worrying. Is this normal?

servers communicating to our postfix MTA. Is this normal. Before kasi hindi
naman ganon kadami ang netstat -vat result. About 100 lines ang output or result
ng netstat.
