The spam protection (incoming scanning) from Spamexperts is included free of charge in all premium web hosting packages for 1 domain.
The spam protection is domain based and it doesn't matter whether you have 1 mailbox or 100 mailboxes. The number of mailboxes is unlimited.
Avoid blacklisting your company's IP addresses by filtering outbound spam, viruses, phishing, malware, ransomware, and other email-based threats. By avoiding your IP addresses being blacklisted, you not only protect your IP addresses but also your reputation.
Use the proactive monitoring of emails and filter reports to benefit from more transparency in the network so that you can more easily identify network abuse. Block compromised accounts automatically or manually with Spamexperts spam protection.
Blacklisting can be extremely costly. Quite apart from the damage to your company's reputation, it takes enormous time and money to identify affected accounts and arrange for them to be removed from the blacklist. Add to this the cost of user support and user dissatisfaction.
