My first post so please forgive me is something is wrong with it. While I don't consider myself a NOOB, I must admit that I'm not a seasoned Linux pro either. I have several services up and running including Samba, Squid, VSFTP, SOCKS5 etc. - all on Redhat 9 with updates and no signs of trouble.
However, I recently made some major changes to my /etc/hosts file in which I denied access to my LAN for certain workstations. I received a message immediately after restarting my network stating that I had mail in /var/spool/mail/root. Examining the file I noticed that it was approximately 20mb in size and contained several hundred Spam e-mails.
I ran ethereal several times and haven't noticed anything particularly suspicious and I do not have this unit set up as a mail server of any kind. The only e-mail I use is 'excite' which is web based and only on certain workstations. SpamAssassin is running; as I was planning to set up a mail server in the future.
Any information relating to this matter is very greatly appreciated. I usually browse these groups when I have troubles and very many helpful people have resolved them, but alas I am perplexed.
