SMTPD(8) SMTPD(8) Page 1 of 5 NAME smtpd - Postfix SMTP server SYNOPSIS smtpd [generic Postfix daemon options] DESCRIPTION The SMTP server accepts network connection requests and performs zero or more SMTP transactions per connection. Each received message is piped through the cleanup(8) daemon, and is placed into the incoming queue as one single queue file. For this mode of operation, the program expects to be run from the master(8) process manager. Alternatively, the SMTP server takes an established connection on standard input and deposits messages directly into the maildrop queue. In this so-called stand-alone mode, the SMTP server can accept mail even while the mail system is not running. The SMTP server implements a variety of policies for connection requests, and for parameters given to HELO, ETRN, MAIL FROM, VRFY and RCPT TO commands. They are detailed below and in the main.cf configuration file. SECURITY The SMTP server is moderately security-sensitive. It talks to SMTP clients and to DNS servers on the network. The SMTP server can be run chrooted at fixed low privilege. STANDARDS RFC 821 (SMTP protocol) RFC 1123 (Host requirements) RFC 1651 (SMTP service extensions) RFC 1652 (8bit-MIME transport) RFC 1854 (SMTP Pipelining) RFC 1870 (Message Size Declaration) RFC 1985 (ETRN command) RFC 2554 (AUTH command) RFC 2821 (SMTP protocol) DIAGNOSTICS Problems and transactions are logged to syslogd(8). Depending on the setting of the notify_classes parameter, the postmaster is notified of bounces, protocol problems, policy violations, and of other trouble. CONFIGURATION PARAMETERS The following main.cf parameters are especially relevant to this program. See the Postfix main.cf file for syntax details and for default values. Use the postfix reload command after a configuration change. Compatibility controls strict_rfc821_envelopes Disallow non-RFC 821 style addresses in envelopes. For example, allow RFC822-style address forms with comments, like Sendmail does. broken_sasl_auth_clients http://www.porcupine.org/postfix-mirror/smtpd.8.html 6/26/01
