issue with extra top level domain appened to mail

[Matthew Davidson [DATACOM]]

Yes it does have the feel of a wayward '.' but... get this...

If I rename my box to 'matdav.datacom.com',  email comes thru from
root at matdav.datacom.com
If I rename my box to 'matdav.datacom.nz',  email comes thru from
root at matdav.datacom.nz
If I rename my box to 'matdav.datacom.com.au',  email comes thru from
root at matdav.datacom.com.au
If I rename my box to 'matdav.datacom.govt.nz',  email comes thru from
root at matdav.datacom.govt.nz
BUT..
If I rename my box to 'matdav.datacom.co.nz',  email comes thru from
root at matdav.datacom.co.nz.co.nz
If I rename my box to 'matdav.datacom.org.nz',  email comes thru from
root at matdav.datacom.org.nz.org.nz
If I rename my box to 'matdav.telecom.co.nz',  email comes thru from
root at matdav.telecom.co.nz.co.nz

I see the same issue with 6.3/6.4.  I've not tested 6.2,  but 6.1 I
don't see this issue.

I'm hoping someone may have the seen the same issue,  or take the time
to build a box and replicate this to confirm it's not just me being a
plonka.

For now I'll just have to rename my 6.3+ boxes to hostname.datacom.com
to work around it.
