Some process caused your panic, which is in this case swi1:net. Any idea what it is? > >ok now onto the next problem. i was running my own mail server until recently as well, but i was getting beaten into the ground by spam. my /var/spool/postfix directory was 1.8 gigabytes. it was all spam i was bouncing from dynamic ips. none of it was getting to my accounts, but my server was getting clogged, since im running this off of adsl. im just wondering what i can do to stop this. the legitimate mail was not a problem at all. also this only started being a problem after a few weeks. as a temporary solution ive stopped postfix and deleted my entire spooled mail directory. however i would like a more permenant solution to these spammers attacking my server. right now postfix is bouncing all emails where the ips dont match the domain name. > > Consider installing spamassassin?
