[Andrew J Cole]

Roger,

Looking at this one again - and this time reading the detail - explains
a lot (see below).

Strictly no.  "mail" is the MUA (Mail User Agent), the interactions we
are seeing here are between the MUA and the MTA (Mail Transfer Agent)
which looks like and claims it is ***sendmail***.  That would explain
why ist not accepting roger-beaumont.co.uk for local delivery!
