now i can send but can't receive mails. this is the mail.log for a sending attempt to my domain: Aug 16 19:37:39 localhost postfix/qmgr: 0FA623BB28A: from=<[email protected]>, size=2232, nrcpt=1 (queue active) Aug 16 19:37:44 localhost postfix/smtp: connect to sistem.ath.cx[18.104.22.168]: Connection refused (port 25) Aug 16 19:37:44 localhost postfix/smtp: 0FA623BB28A: to=<[email protected]>, orig_to=<[email protected]>, relay=none, delay=1809, status=deferred (connect to sistem.ath.cx[22.214.171.124]: Connection refused) sistem.ath.cx is not my domain. i believe i deleted this domain name from everywhere: /etc/hosts, from the ispconfig, from the networking panel... and i reboot after every change, but it's still saying 'sistem.ath.cx' how can i fix this? it's possible from ispconfig? it's not a solution but should i add the sistem.ath.cx records?
