hi .

what is the basic command to send a mail in command line, using
sendmail program.

somebody help me.

Thanks

You normally wouldn't use the sendmail program to send an email from the command line. Usually you would use something like the mail command.

#mail -s "This is the subject" recipient@domain.com
Type message here
CTRL-D when done

or if you want to send a file as the text of a message:

#mail -s "This is the subject" recipient@domain.com < /path_to/message.txt

Using sendmail directly:

/path/to/sendmail -f from@domain.com address@domain.com
<insert custom headers>
To: Someone <someone@domain.com>
From: Me <me@domain.com>
Subject: Hey!
</custom headers>
Type message. Blah blah blah.
.

That's it.... a period (.) on a line by itself sends the message. Put any customer headers you want in the beginning, where I've marked <insert custom headers> and they will be sent as a header.

Good luck.
