More Information About Sorbs Block

Specific SORBS BLOCK Details

This SORBS Zone lists IP addresses and networks that have requested to be omitted from the SORBS scanning and processing. SORBS makes this zone available so that administrators that wish to use SORBS can identify mail from these IPs as having not been included in other zones.

SORBS General Info

The SORBS (Spam and Open Relay Blocking System), owned and operated by Proofpoint, Inc., provides free access to its DNS-based Block List (DNSBL) to effectively block email from more than 12 million host servers known to disseminate spam, phishing attacks, and other forms of malicious email. The list typically includes email servers suspected of sending or relaying spam, servers that have been hacked and hijacked, and those with Trojan infestations. In an attempt to provide preemptive protection, SORBS also lists servers with dynamically allocated IP addresses.

Sorbs Block Reports Subnets

Subnet-based Blacklists are used to reject email from entire ranges of IP Addresses, i.e. providers that are hosting companies sending spam, as well as single IP Addresses that may fall in that range of IP Address.

Sorbs Block Requires A Manual Delisting Request

This blacklist does support a manual request to remove or delist your IP Address from their database. Please note that removal requests that are submitted without addressing the core problem will likely result in your IP Address or Domain being relisted in that database, which can cause subsequent problems and extended listing periods without release.

Your Email Deliverability is in Jeopardy!

Blacklisting is a sign that you are not actively managing your email deliverability. Other technologies - SPF, DKIM and DMARC are now just as important to get your email placed in the Inbox of your recipients. If you aren’t managing email deliverability, your message may never be heard.

MxToolbox Delivery Center Features:

  • Insight into your SPF, DKIM and DMARC configuration to ensure your sending email properly
  • DMARC Compliance checks for all of your reported email
  • Adaptive Blacklist Monitoring of all your email senders
  • Recommendations for improving DMARC compliance and DMARC policies
  • Event-based reminders for emergent issues and on-going maintenance

DMARC is a necessity for your business!
