This problem does not exist on our servers, it has to do with the recipients servers. You should contact the provider of the recipient.

the problem is that if exim does a reverse lookup
(my home server does it also)
the ip 74.86.116.190 (it's cossacks.x10....)
resolves to cossacks.x10hosting
and not to cossacks.x10hosting.com
therefor the exim server denies!
if i try a
dig -x 74.86.116.190
the result is
cossacks.x10hosting
and not
cossacks.x10hosting.com !
Can anybody correct this in zonefiles for cossacks

regards
Harald
