Hi, I have sendmail configured on a CentOS linux machine using scalix and I am finding alot of the following error messages in the mailq: -> Deferred: ntvirus3.mitts.net.: No route to host -> Transient parse error -- message queued for future delivery -> Deferred: Connection timed out with peakings.com. Can someone please explain to me what these errors mean? And how can I resolve them (if any)? Thanks in anticipation for your help.
