Time Problem

[MountaiNet Tech Support]

This doesnt sound directly related to qmail, but if I send e-mail from a
Windows based e-mail program using my qmail server for SMTP, the time is
displayed properly when its checked on another Windows based e-mail client.
 However, if I send directly off of my qmail server to a Windows based
e-mail client the time is about 5 hours ahead of the actual time.  The time
and timezone are set correctly on the server.  Any ideas?
