Hi everyone, Since last friday i saw that my qmail qeue had over 1000 mail.I checked and saw that almost 500 of them where coming ftom a domain no t in my IP and were going to a recipient not in IP too. I thought it was relaying.I have added the domain to my black list but i need some help with the realying issue.I have an open relay but with both smtp and pop (10 min) auth. How did he get a relay despite the auths? And if i set from my plesk 7.5.3 the relay mode to off what my clients will not be able to do? Should i set relaying to off? What is MAPS? Thanks I have choosen to have a unique IP for qmail than the one pointing to the domain.Does that matter?
