Sort of... that's about the same logic function, but the process is
more like this: tcpserver accepts a connection. It checks its rules
file to see whether to allow or deny the connection, and sets any
environment variables listed in the rules file. tcpserver invokes
qmail-smtpd. qmail-smtpd checks the environment for RELAYCLIENT. If
that variable is set, its value is appended to the local part of the
destination address and the message is accepted. Otherwise,
qmail-smtpd checks for the desination domain in rcpthosts: if it's
there, the message is accepted; if it's not, it isn't.
