Signal Handling
The Milter library, libmilter.a, manages signal handling, and the
signals do not directly influence filter applications.
Sendmail 8.13.3 includes the following signal handlers:
• Stop – Specifies that new connections from the MTA are not accepted
but existing connections are allowed to continue.
• Abort – Specifies that all filter applications will be stopped after the
next communication with Sendmail happens.
