We had a very unusual and scary experience for one business day. We make
extesive use of Sendmail on out HP3000 (MPE/iX 6.5 pp2). Out of the blue
the email delivery stops and a ‘rogue’ ip address is being broadcast.
Almost 24 hours to the minute eureka it is suddenly OK again. Can anyone
offer any suggestions / guidence? And as a secondary can anyone advise
what the DSN n.0.0 messages actually mean? I am particularly interested in
what 5.0.0 indicates.
