I am trying to integrate a new subdomain into our mail system here at
Intergraph, and am having a strange problem.  When mail gets sent from
a Sun installation in Boulder to our main mailhub here in Huntsville (an
Intergraph 6505), the From: address gets a ^P appended to it betwixt here
and there, so that the sendmail process on the mailhub does not recognize
the address, and proceeds to try to fully qualify it, leaving us with

user@host.dazixco.ingr.com^P.ingr.com

, which is hardly useful.  Does anyone know where a spurious character like
this can come from?  There are no strangely embedded characters in the 
/etc/sendmail.cf file on the machine in Boulder, and it is rewriting the
addresses correctly.

Does anyone have any suggestions as to how I might find who's responsible
for adding the ^P and how to stop it?  It only appears to happen on the
From: address; none of the other headers are so affected.
