SIGINT

Handle Control-C sendmail signal

Before V8.7, when sendmail was run in rule-testing mode with -bt, it could be killed with a Control-C (SIGINT). Beginning with V8.7, SIGINT is handled specially. This allows you to resume testing whenever something such as a bad DNS lookup takes excessively long to complete.
