It's easy enough to find the single reference to unsetenv() and comment it
out.  On systems that use the TZ environment variable to set the user's
timezone (like Sys V systems), sendmail needs to call unsetenv("TZ") to
keep users from fooling sendmail as to what time the message was sent.
Current Ultrix systems don't use this convention, so commenting out
the unsetenv() doesn't hurt anything.
