This question already has an answer here:
I want to send a html message with Mailx. When I try the following command
mailx -s "Subject" user@gmail.com < email.html
I get the content of email.html in plain text. In the message the header Content-Type is set to text/plain. The -a option tries to send a file so I didn't find out how to modify the header. This answer almost worked, it sets well the Content-Type to text/html but doesn't substitute the default Content-Type which is text/plain.
mailx -s "$(echo -e "This is the subject\nContent-Type: text/html")" user@gmail.com < email.html
gives this result :
From: send@gmail.com
To: user@gmail.com
Subject: This is the subject
Content-Type: text/html
Message-ID: <538d7b66.Xs0x9HsxnJKUFWuI%maikeul06@gmail.com>
User-Agent: Heirloom mailx 12.4 7/29/08
MIME-Version: 1.0
boundary="=_538d7b66.z5gaIQnlwb1f/AOkuuC+GwF1evCaG/XIHQMbMMxbY6satTjK"
This is a multi-part message in MIME format.
--=_538d7b66.z5gaIQnlwb1f/AOkuuC+GwF1evCaG/XIHQMbMMxbY6satTjK
Content-Type: text/plain; charset=us-ascii
Content-Transfer-Encoding: 7bit
Content-Disposition: inline
<html>
<body>
<p>Helo wolrd</p>
</body>
</html>
PS : I also tried with uuencode. When I try to display the message in the webmail I get a blank page...
It's easy, if your mailx command supports the -a (append header) option:
$ mailx -a 'Content-Type: text/html' -s "my subject" user@gmail.com < email.html
If it doesn't, try using sendmail:
# create a header file
$ cat mailheader
To: user@gmail.com
Subject: my subject
Content-Type: text/html
# send
$ cat mailheader email.html | sendmail -t
There are many different versions of mail around. When you go beyond mail -s subject to1@address1 to2@address2
With some mailx implementations, e.g. from mailutils on Ubuntu or Debian's bsd-mailx, it's easy, because there's an option for that.
mailx -a 'Content-Type: text/html' -s "Subject" to@address <test.htmlWith the Heirloom mailx, there's no convenient way. One possibility to insert arbitrary headers is to set editheaders=1 and use an external editor (which can be a script).
## Prepare a temporary script that will serve as an editor. ## This script will be passed to ed. temp_script=$(mktemp) cat <<'EOF' >>"$temp_script" 1a Content-Type: text/html . $r test.html w q EOF ## Call mailx, and tell it to invoke the editor script EDITOR="ed -s $temp_script" heirloom-mailx -S editheaders=1 -s "Subject" to@address <<EOF ~e . EOF rm -f "$temp_script"With a general POSIX mailx, I don't know how to get at headers.
If you're going to use any mail or mailx, keep in mind that
This isn't portable even within a given Linux distribution. For example, both Ubuntu and Debian have several alternatives for mail and mailx.
When composing a message, mail and mailx treats lines beginning with ~ as commands. If you pipe text into mail, you need to arrange for this text not to contain lines beginning with ~.
If you're going to install software anyway, you might as well install something more predictable than mail/Mail/mailx. For example, mutt. With Mutt, you can supply most headers in the input with the -H option, but not Content-Type, which needs to be set via a mutt option.
mutt -e 'set content_type=text/html' -s 'hello' 'to@address' <test.html
Or you can invoke sendmail directly. There are several versions of sendmail out there, but they all support sendmail -t to send a mail in the simplest fashion, reading the list of recipients from the mail. (I think they don't all support Bcc:.) On most systems, sendmail isn't in the usual $PATH, it's in /usr/sbin or /usr/lib.
cat <<'EOF' - test.html | /usr/sbin/sendmail -t
To: to@address
Subject: hello
Content-Type: text/html
EOF
I had successfully used the following on Arch Linux (where the -a flag is used for attachments) for several years:
mailx -s "The Subject $( echo -e "\nContent-Type: text/html" user@gmail.com < email.html
This appended the Content-Type header to the subject header, which worked great until a recent update. Now the new line is filtered out of the -s subject. Presumably, this was done to improve security.
Instead of relying on hacking the subject line, I now use a bash subshell:
(
echo -e "Content-Type: text/html\n"
cat mail.html
) | mail -s "The Subject" -t user@gmail.com
And since we are really only using mailx's subject flag, it seems there is no reason not to switch to sendmail as suggested by @dogbane:
(
echo "To: user@gmail.com"
echo "Subject: The Subject"
echo "Content-Type: text/html"
echo
cat mail.html
) | sendmail -t
The use of bash subshells avoids having to create a temporary file.
EMAILCC=" -c user1@dominio.cl,user2@dominio.cl"
TURNO_EMAIL="user@dominio.cl"
mailx $EMAILCC -s "$(echo "Status: Control Aplicactivo \nContent-Type: text/html")" $TURNO_EMAIL < tmp.tmp
Well, the "-a" mail and mailx in Centos7 is "attach file" not "append header." My shortest path to a solution on Centos7 from here: stackexchange.com
Basically:
yum install mutt
mutt -e 'set content_type=text/html' -s 'My subject' me@my.com < msg.html
If you use AIX try this This will attach a text file and include a HTML body If this does not work catch the output in the /var/spool/mqueue
#!/usr/bin/kWh
if (( $# < 1 ))
then
echo "\n\tSyntax: $(basename) MAILTO SUBJECT BODY.html ATTACH.txt "
echo "\tmailzatt"
exit
fi
export MAILTO=${1-noreply@visweb.co.za}
