qmail-qmtpd - receive mail via QMTP
qmail-qmtpd
qmail-qmtpd receives mail messages via the Quick Mail Transfer Protocol (QMTP) and invokes qmail-queue to deposit them into the outgoing queue. qmail-qmtpd must be supplied several environment variables; see tcp-environ(5).
qmail-qmtpd supports the rcpthosts, morercpthosts RELAYCLIENT, databytes, and DATABYTES mechanisms described in qmail-smtpd(8) .
If the environment variable HIDE_HOST is set, qmail-qmtpd does not write hostnames and IP addresses in the received header.
