Hi Per, Sorry for posting the same logs twice, and sorry for taking so
long to get back (im stuck in jakarta for a few weeks and only just
had chance to access internet.)

Firstly, sendmail is set to deliver mail for praybourne.local to our
exchange server via [IP Address] and ignore MX records (using
mailertable). This has been set for around 3 years and has never
failed before we moved. Yes on this machine hosts is set before DNS,
the contents of hosts is:
127.0.0.1 localhost localhost.localdomain
212.169.48.90 mail.praybourne.co.uk mail
10.10.5.252 exchangeserver.praybourne.local

DNS is set as:
1. 10.10.5.252
2. 195.8.69.7
3. 195.8.69.12

So looking at this, its searching DNS for praybourne.local, but what i
dont understand is why this worked a couple of weeks ago, but not now.
why is not using hosts first?!!

If in mailertable its specified not to look up MX records, why does it
still use DNS (im really confused)
Is it possible that between moving premises our sendmail configuration
has got messed up?

Dave.
