For the sake of compatibility with existing 24 1.1.1.4 tron applications, some Sendmail command-line options are recognized but 25 1.1.1.4 tron silently ignored. 26 1.1.1.4 tron 27 1.1.1.4 tron By default, Postfix <a href="sendmail.1.html"><b>sendmail</b>(1)</a> reads a message from standard input 28 1.1.1.4 tron until EOF or until it reads a line with only a <b>.</b> character, and 29 1.1.1.4 tron arranges for delivery. Postfix <a href="sendmail.1.html"><b>sendmail</b>(1)</a> relies on the <a href="postdrop.1.html"><b>postdrop</b>(1)</a> 30 1.1.1.4 tron command to create a queue file in the <b>maildrop</b> directory. 31 1.1.1.4 tron 32 1.1.1.4 tron Specific command aliases are provided for other common modes of opera- 33 1.1.1.4 tron tion: 34 1.1.1.4 tron 35 1.1.1.4 tron <b>mailq</b> List the mail queue.
