Sendmail命令将文件作为电子邮件正文以及附件发送 [英] Sendmail command to send a file as an email body as well as attachment

问题描述

我想使用bash中的sendmail命令发送电子邮件.电子邮件应通过阅读Input_file_HTML来获取其内容，并且还应发送相同的输入文件作为附件.为此，我尝试了以下方法.

I want to send an email using sendmail command in bash. The email should get it's body by reading Input_file_HTML and it should send same input file as an attachment too. To do so I have tried the following.

sendmail_touser() {
cat - ${Input_file_HTML} << EOF | /usr/sbin/sendmail -oi -t
From: ${MAILFROM}
To: ${MAILTO}
Subject: $1
Content-Type: text/html; charset=us-ascii
cat ${Input_file_HTML}
Content-Transfer-Encoding: 7bit
MIME-Version: 1.0
Content-Disposition: attachment; filename: ${Input_file_HTML}
EOF
}

上面的命令给出的电子邮件仅带有Input_file_HTML的附件，而不是将其写在电子邮件正文中.您能帮我指导一下吗?我正在使用Outlook作为电子邮件客户端.我什至在上面的命令中删除了cat命令，但是它也无法正常工作.

The above command is giving an email with only the attachment of Input_file_HTML and it is not writing it in the body of email. Could you please help/guide me on same? I am using outlook as the email client. I have even removed the cat command in above command, but it also is not working.

推荐答案

使用mutt代替?

echo "This is the message body" | mutt -a "/path/to/file.to.attach" -s "subject of message" -- [e-mail]

要在Debian系统上安装mutt:

To install mutt on Debian systems:

sudo apt-get install -y mutt

编辑，如果您只能使用sendmail:

sendmail_attachment() {
    FROM="$1"
    TO="$2"
    SUBJECT="$3"
    FILEPATH="$4"
    CONTENTTYPE="$5"

    (
    echo "From: $FROM"
    echo "To: $TO"
    echo "MIME-Version: 1.0"
    echo "Subject: $SUBJECT"
    echo 'Content-Type: multipart/mixed; boundary="GvXjxJ+pjyke8COw"'
    echo ""
    echo "--GvXjxJ+pjyke8COw"
    echo "Content-Type: text/html"
    echo "Content-Disposition: inline"
    echo "<p>Message contents</p>"
    echo ""
    echo "--GvXjxJ+pjyke8COw"
    echo "Content-Type: $CONTENTTYPE"
    echo "Content-Disposition: attachment; filename=$(basename $FILEPATH)"
    echo ""
    cat $FILEPATH
    echo ""
    ) | /usr/sbin/sendmail -t
}

像这样使用:

sendmail_attachment "[e-mail]" "[e-mail]" "Email subject" "/home/user/file.txt" "text/plain"
