-** SYSERR -- Print error message.
-**
-** Prints an error message via printf to the diagnostic output.
-**
-** If the first character of the syserr message is `!' it will
-** log this as an ALERT message and exit immediately. This can
-** leave queue files in an indeterminate state, so it should not
-** be used lightly.
-**
-** Parameters:
-** fmt -- the format string. If it does not begin with
-** a three-digit SMTP reply code, either 554 or
-** 451 is assumed depending on whether errno
-** is set.
-** (others) -- parameters
-**
-** Returns:
-** none
-** Through TopFrame if QuickAbort is set.
-**
-** Side Effects:
-** increments Errors.
-** sets ExitStat.
