Do you get any mail from them or does this always happen?

define(`confTO_COMMAND', `1m')dnl

Why did you choose this?

Kcheck_client dns -R a -T T -q

Where/how is this used?

mx0a-0017d901.pphosted.com [208.84.65.218]

Maybe 1m is too short, esp. if DNS lookups take a while.
The default is much longer - see the docs.
