Thanks. Some digging indicates that this is equivalent to doveadm reload. Both paths ultimately send a SIGHUP to the server which initiates a full reload of the configuration.

I'll be combining this with a restart of sendmail. Alas, I don't see a way to get it to reload its configuration.

Should be the same way: send a SIGHUP signal to the parent process.

I'm not sure whether this will cause the sendmail worker processes to dump their cients, but if it did, SMTP is fault tolerant enough that delivery should be retried later.
