They are mainly used to publish lists of addresses that are known to be involved in spam activities. All mail servers can be configured to reject or flag messages that have been sent from a site listed on one or more such RBL blacklists.<\/p>\n<p>This RBL blacklist is an effort to stop email spam. It is a \"blacklist\" of locations on the Internet that are notorious for sending email spam. The locations consist of IP addresses that are most often used to publish the addresses of computers or networks linked to spam. Most mail server software can be configured to reject or flag messages that have been sent from a site listed on one or more of these lists.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div><\/div><div data-vc-full-width=\"true\" data-vc-full-width-temp=\"true\" data-vc-full-width-init=\"false\" class=\"vc_row wpb_row vc_row-fluid vc_custom_1669133976112 vc_row-has-fill vc_row-o-content-middle vc_row-flex\"><div class=\"wpb_column vc_column_container vc_col-sm-6\"><div class=\"vc_column-inner\"><div class=\"wpb_wrapper\"><div id=\"ultimate-heading-21976a15575c07eeb\" class=\"uvc-heading ult-adjust-bottom-margin ultimate-heading-21976a15575c07eeb uvc-9297\" data-hspacer=\"no_spacer\"  data-halign=\"left\" style=\"text-align:left\"><div class=\"uvc-heading-spacer no_spacer\" style=\"top\"><\/div><div class=\"uvc-main-heading ult-responsive\"  data-ultimate-target='.uvc-heading.ultimate-heading-21976a15575c07eeb h4'  data-responsive-json-new='{\"font-size\":\"desktop:45px;tablet_portrait:34px;\",\"line-height\":\"desktop:50px;tablet_portrait:44px;\"}' ><h4 style=\"--font-weight:theme;color:#ffffff;\">Let's work together<\/h4><\/div><div class=\"uvc-sub-heading ult-responsive\"  data-ultimate-target='.uvc-heading.ultimate-heading-21976a15575c07eeb .uvc-sub-heading '  data-responsive-json-new='{\"font-size\":\"desktop:25px;tablet_portrait:20px;\",\"line-height\":\"desktop:30px;tablet_portrait:30px;\"}'  style=\"font-weight:bold;color:#ffffff;\">We would love to hear about your next project and show you how we can help.<\/div><\/div><\/div><\/div><\/div><div class=\"wpb_column vc_column_container vc_col-sm-6\"><div class=\"vc_column-inner\"><div class=\"wpb_wrapper\"><style type=\"text\/css\" data-type=\"the7_shortcodes-inline-css\">#default-btn-fe066e1174e3a4e558f04bc44e1e27ce {\n  border-radius: 0px;\n  font-size: 24px;\n  line-height: 26px;\n}\n.btn-shadow#default-btn-fe066e1174e3a4e558f04bc44e1e27ce {\n  box-shadow: 0 1px 6px rgba(0,0,0,0.12);\n  transition: box-shadow 0.2s ease-out, opacity 0.45s;\n}\n.btn-shadow#default-btn-fe066e1174e3a4e558f04bc44e1e27ce:hover {\n  box-shadow: 0 5px 11px 0 rgba(0,0,0,0.18), 0 4px 15px 0 rgba(0,0,0,0.15);\n}\n.btn-3d#default-btn-fe066e1174e3a4e558f04bc44e1e27ce:hover {\n  box-shadow: 0px 2px 0px 0px #e0e0e0;\n}\n.btn-flat#default-btn-fe066e1174e3a4e558f04bc44e1e27ce {\n  box-shadow: none;\n}\n.btn-flat#default-btn-fe066e1174e3a4e558f04bc44e1e27ce:hover {\n  box-shadow: none;\n}\n#default-btn-fe066e1174e3a4e558f04bc44e1e27ce.ico-right-side > i {\n  margin-right: 0px;\n  margin-left: 8px;\n}\n#default-btn-fe066e1174e3a4e558f04bc44e1e27ce > i {\n  margin-right: 8px;\n  font-size: 24px;\n}\n#default-btn-fe066e1174e3a4e558f04bc44e1e27ce:not(:hover) {\n  border-width: 0px;\n  color: #ffffff;\n  padding: 26px 10px 26px 10px;\n}\n#default-btn-fe066e1174e3a4e558f04bc44e1e27ce:not(:hover) * {\n  color: #ffffff;\n}\n#default-btn-fe066e1174e3a4e558f04bc44e1e27ce:hover {\n  border-width: 0px;\n  color: #000000;\n  background: #ffffff !important;\n  padding: 26px 10px 26px 10px;\n}\n#default-btn-fe066e1174e3a4e558f04bc44e1e27ce:hover * {\n  color: #000000;\n}\n#default-btn-fe066e1174e3a4e558f04bc44e1e27ce.ico-right-side > i {\n  margin-right: 0px;\n  margin-left: 8px;\n}\n#default-btn-fe066e1174e3a4e558f04bc44e1e27ce > i {\n  margin-right: 8px;\n}<\/style><div class=\"btn-align-center\"><a href=\"\/en\/contact\/\" class=\"default-btn-shortcode dt-btn link-hover-off full-width-btn btn-flat\" id=\"default-btn-fe066e1174e3a4e558f04bc44e1e27ce\" title=\"Mobile application development\"><i class=\"icomoon-the7-font-the7-arrow-29\"><\/i><span>Ask us for a quote<\/span><\/a><\/div><\/div><\/div><\/div><\/div><div class=\"vc_row-full-width vc_clearfix\"><\/div><div id=\"table-of-contents-2\" class=\"vc_row wpb_row vc_row-fluid justify vc_custom_1669133631174\"><div class=\"wpb_column vc_column_container vc_col-sm-12\"><div class=\"vc_column-inner\"><div class=\"wpb_wrapper\">\n\t<div class=\"wpb_text_column wpb_content_element  justify\" >\n\t\t<div class=\"wpb_wrapper\">\n\t\t\t<h2><span class=\"ez-toc-section\" id=\"Listas_Negras_RBL\"><\/span>RBL Blacklists<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>RBL email blacklists are everywhere.

If your IP is on the lists, especially the Spamhaus lists, you will have major deliverability problems with your emails.<\/p>\n<p>Spamcop &amp; CBL are used by default in many shared hosting control panels such as cPanel. If you are a small business, you will most likely have your email with a shared host using these email blacklists. WHM \/ cPanel supports the Spamcop and Spamhaus Zen lists. The Zen list is an aggregated list of the entire Spamhaus list which also includes the CBL.<\/p>\n<p>Barracuda is used by a number of larger companies and cloud-based email security services. If you are doing business with larger companies, you may be protecting your email with a Barracuda anti-spam appliance. Barracuda also makes your list available to others. So even if the recipient server isn't using your device, they could still be using your data.<\/p>\n<p>There are websites where you can check if your IP is listed on some RBL blacklists. Some of them are: <a href=\"https:\/\/rblwatcher.com\" target=\"_blank\" rel=\"noopener noreferrer\">rblwatcher.com<\/a> or anti-abuse.org.
