Sendmail命令将文件作为电子邮件正文和附件发送[重复]

使用 mutt 相反

echo "This is the message body" | mutt -a "/path/to/file.to.attach" -s "subject of message" -- recipient@domain.com

要安装 杂种狗 在Debian系统上:

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
}

使用方式如下:

sendmail_attachment "to@example.com" "from@example.com" "Email subject" "/home/user/file.txt" "text/plain"
