show runqueue

show stats
Displays runtime statistics concerning smtpd(8).
When smtpd receives a message, it generates a message-id for the message,
and one message-uid per recipient. The message-id consists of a
timestamp followed by a random identifier that is guaranteed to be unique
on the host system. The message-uid consists of the message-id followed
by a random identifier that is also guaranteed to be unique between
recipients of the same message.
A command which specifies a message-id applies to all recipients of a
message; a command which specifies a message-uid applies to a specific
recipient of a message.
