Hi List, Well, there was already similar problem mailed on this list, but somehow I missed the solution. The problem is next - suddenly I began to experience delivery problem with mail, INCOMING to my domain. I got the error "Deferred: Name server: host.domain.co.il: host name lookup failure" for EACH host in the domain. I can ping from the mail server any host in the domain and I can telnet 25 any one of them. Nothing was changed into Sendmail configuration, few A records was added to DNS during two last days. Is there specific sendmail mailing list with big archive?
