Hi All,
We are using a Linux sendmail as our email server.For few days weare facing with a problem of worm that sends emails(spam) automatically,due to this problem some ISP's have blocked us.Is there a software/antivirus to resolve this problem. Alternately how can we find out the spam software,whether is a virus/is due to open relay or some other issue.
Mmmm, relevant logs? Is this host also acting as a NAT gateway? Are you on any DNSBLs? what are the bounce messages you are getting? Are you running SA/dspam on your gateway?
