Sendmail interprets exit codes from programs according to sysexits.h.
If you've written your own mailer, it should either exit with a zero
return code, or with one of the codes defined in sysexits.h.

If you look in sysexits.h, you will see that there is a return code
EX_TEMPFAIL defined to be use for temporary failures.  If your mailer
program calls "exit(EX_TEMPFAIL)" when it detects a temporary failure,
the mail should be retried.
