A mail transfer agent such as Postfix is both a SMTP server to receive mail from other MTAs, and a SMTP client, to relay mail to other MTAs. The trailing "d" in smtpd(8) is a Unix standard to indicate a daemon or server process. smtpd is the server, smtp(8) is the client. The postconf(5) setting prefix of smtp_ indicates client-specific settings, whereas smtpd_ indicates server settings. See wikipedia about SMTP and mail for general information, and here for Postfix design: http://www.postfix.org/OVERVIEW.html > What port is good for sent email via outlook express with postfix > TLS 25 with requires a secure connections (SSL) or port 465 ? Outlook Express is buggy, broken, and not supported by its maker. Generally a very poor choice, considering that many good and free alternatives exist. The smtps protocol (port 465) was deprecated by the move of SSL to TLS 1.0. New sites should not be implementing smtps. RFC 4409 designates port 587 for mail submission from clients. See the lines for submission in master.cf -- this is commented by default, but can be enabled easily. A submission service usually requires SASL AUTH, so see here as well: http://www.postfix.org/SASL_README.html -- Offlist mail to this address is discarded unless "/dev/rob0" or "not-spam" is in Subject: header
