3 | # This program gives you low level control over an SMTP conversation. | |
4 | # | |
5 | # This program delivers a mail message to an SMTP server. Command line | |
6 | # options tell what server to use and determine the commands this program | |
7 | # sends to it. The program reads the mail message itself from | |
8 | # Standard Input. | |
9 | # | |
10 | # This program does not generate headers inside the mail message (e.g. | |
11 | # RFC 822 headers). You can use the program 'makemail' to do that. | |
12 | # | |
13 | # This program does not extract any envelope information from the mail | |
14 | # message or rewrite the message in any way. | |
