Postfix has an SMTP server (smtpd(8)) and an SMTP/LMTP client (smtp(8)
and lmtp(8) are the same program under two names).
The documentation of "postconf -[Aa]" makes the appropriate
distinctions:

This feature is available with Postfix 2.3 and later.

The SMTP server receives mail from another mail handling system into the
Postfix queue. The SMTP and LMTP client deliver mail mail from the
Postfix queue to another mail handling system.
