sendoff() defined in deliver.c calls openmailer().  If the return
value of openmailer() was negative, sendoff() returns -1.  This will
cause fatal error.  The E-mail will be sent back to sender.  But
openmailer() returns negative value even if the error is not fatal.
For example, when it failed to create pipe, or when it failed to fork.

So I think sendoff() returns ExitStat in stead of -1.  And the global
variable ExitStat should be set to have proper status in openmailer().

Excuse my English.
