Protect your reputation and guard against internal and external threats with email filter software

MSP customers expect seamless, uninterrupted email—but IP blacklisting can block email traffic and stand in the way. Whether it’s a compromised computer linked to a botnet, a fraudulent account, or a user sending out bulk email, the consequence can be irreparable damage to a network’s reputation. 

Low network reputation can lead to emails not being sent, which in turn leads to customer frustration and time-consuming investigations. SolarWinds® Mail Assure is an email security solution that gives you total control over mail protection and lets you view, release, remove, blacklist, and whitelist messages as needed. The Intelligent Protection and Filtering Engine in Mail Assure updates continuously using data from your users to help prevent known internal and external threats, allowing you to protect customers’ IP reputations.
 

Manage outbound spam to keep your customers off IP blacklists

IP Blacklist Prevention Solution 2

Manage outbound spam to keep your customers off IP blacklists

While many organizations are proactive about handling inbound spam, outbound spam is often neglected—which is a mistake. Outbound email protection is just as important as protecting inboxes against incoming threats. If outbound spam causes low network reputation and business emails aren’t going out, MSPs will have to identify and suspend the abused hosting resources while dealing with customer complaints. You’ll also have to communicate to the email recipients to request IP blacklist removal for the affected IP addresses.

Outbound email filtering helps stop spam and viruses from being sent out by hijacked accounts in your customers’ systems. SolarWinds Mail Assure filters emails with 99.999% accuracy and abuse management features show you which accounts are sending out spam, helping you prevent IP blacklisting before it negatively impacts your reputation. Mail Assure also supports SPF, DKIM, and DMARC  to help protect against spoofing.

Frequently Asked Questions

What is IP blacklisting?

A blacklist is a list of entities that are not allowed to communicate with or log into a computer, site, or network because they are known sources of spam. Blacklists typically consist of IP addresses, but they can also include user IDs, domains, email addresses, MAC addresses, or programs. Blacklists are also called domain name system blacklists, or DNSBLs. 

Blacklists are common features in antivirus programs, spam filters, and intrusion detection systems to help prevent potential attacks. Outbound email filtering solutions can help identify which users or domains are sending out spam and block such emails from leaving the network. Some solutions offer recommended blacklists full of likely targets, but blacklists work best when they are customized to your network’s unique needs.
 

How do you check if an IP address is blacklisted?

Many MSPs carefully curate their spam blacklists according to their needs or their customers’ needs, and there’s no surefire way to run an IP blacklist check for these customized lists. However, if you suspect that your customer is on an IP blacklist, the easiest way to check is to use an IP blacklist check website. These sites will cross-reference your IP address against the most popular lists to see if you have been blacklisted.

There are many options out there, but some of the most popular IP blacklist check sites are:

  1. Barracuda Reputation Block List
  2. Invaluement
  3. MXToolBox
  4. MultiRBL

How do you avoid getting blacklisted?

Unfortunately, it’s very easy for your IP to end up on a blacklist—a high spam complaint or a bad email list is all it takes. Here are a few common ways to end up on an IP blacklist:

  1. Spam complaints: Any time a user marks your email as spam, ISPs will think your email content or email hygiene is bad even if they’re legitimate.
  2. Bad addresses: Too many bounced emails indicates your list might not be opted in or current.
  3. Large email lists: If your email list grows exponentially in a short amount of time, ISPs will suspect you purchased the list and blacklist you. 

To help avoid getting blacklisted, you can utilize email filter software that prevents blacklisting, manages outbound spam, and protects your IP reputation.  
 

How do you get your IP off a blacklist?

Sometimes IP addresses wind up on blacklists by mistake. For example, an authorized user might send out one too many bulk emails and have their IP address marked as spam by email filter software. This can seriously hurt the reputation of a business.

If your IP is on a blacklist, it is possible to get it removed. After checking the IP blacklist check sites for your IP, the site will provide instructions on how to get it removed if found. IP blacklist removal is typically simple, but it’s important to be proactive. DNSBL sites like to see that you’re trying to fix your blacklist status as quickly as possible.
