If I understand you correctly, you want to send mail in HTML format using linux sendmail command. This code is working on Unix. Please give it a try.
echo "From: [email protected]
To: [email protected]
MIME-Version: 1.0
Content-Type: multipart/alternative;
boundary='PAA08673.1018277622/server.xyz.com'
Subject: Test HTML e-mail.
This is a MIME-encapsulated message
--PAA08673.1018277622/server.xyz.com
Content-Type: text/html
<html>
<head>
<title>HTML E-mail</title>
</head>
<body>
<a href='http://www.google.com'>Click Here</a>
</body>
</html>
--PAA08673.1018277622/server.xyz.com
" | sendmail -t
For the sendmail configuration details, please refer to this link. Hope this helps.
To follow up on the previous answer using mail :
Often times one's html output is interpreted by the client mailer, which may not format things using a fixed-width font. Thus your nicely formatted ascii alignment gets all messed up. To send old-fashioned fixed-width the way the God intended, try this:
{ echo -e "<pre>"
echo "Descriptive text here."
shell_command_1_here
another_shell_command
cat <<EOF
This is the ending text.
</pre><br>
</div>
EOF
} | mail -s "$(echo -e 'Your subject.\nContent-Type: text/html')" [email protected]
You don't necessarily need the "Descriptive text here." line, but I have found that sometimes the first line may, depending on its contents, cause the mail program to interpret the rest of the file in ways you did not intend. Try the script with simple descriptive text first, before fine tuning the output in the way that you want.
Found solution in http://senthilkl.blogspot.lu/2012/11/how-to-send-html-emails-using-sendemail.html
sendEmail -f "oracle@server" -t "[email protected]" -u "Alert: Backup complete" -o message-content-type=html -o message-file=$LOG_FILE -a $LOG_FILE_ATTACH
I understand you asked for sendmail but why not use the default mail? It can easily send html emails.
Works on: RHEL 5.10/6.x & CentOS 5.8
Example:
cat ~/campaigns/release-status.html | mail -s "$(echo -e "Release Status [Green]\nContent-Type: text/html")" [email protected] -v

-a option?
Cf. man page:
-a file
Attach the given file to the message.
Result:
Content-Type: text/html: No such file or directory
This page should help - http://www.zedwood.com/article/103/bash-send-mail-with-an-attachment
It includes a script to send e-mail with a MIME attachment, ie with a HTML page and images included.
The following works:
(
echo "From: ${from}";
echo "To: ${to}";
echo "Subject: ${subject}";
echo "Content-Type: text/html";
echo "MIME-Version: 1.0";
echo "";
echo "${message}";
) | sendmail -t
For troubleshooting msmtp, which is compatible with sendmail, see:
It's simpler to use, the -a option :
cat ~/campaigns/release-status.html | mail -s "Release Status [Green]" -a "Content-Type: text/html" [email protected]
