Spam Control
Spam can become a big problem. WHMCS comes with spam control filters to reduce the amount of spam you receive. The spam control features will allow you to block email address and keywords or phrases that appear in either the message subject or body. which pipe into the ticket system from email. Messages that you receive via the contact or submit ticket pages are not subject to these spam controls. For those, we recommend using reCaptcha.

Adding a Blocked Email Address
There are two ways to block an email address from opening tickets. The first is the easiest: when viewing a ticket from the email you want to block, click the Block Sender button next to the ticket opener's details.
For the second method, go to Configuration () > System Settings > Support > Spam Control and use the Add box to enter the email you want to block. Then, submit the form to add it.
Blocking Keywords or Phrases
To set up keywords or phrases that, if they're in an email, will prevent the email from opening a ticket, go to Configuration () > System Settings > Support > Spam Control. You can then enter the words or phrases and choose where the system looks for them (either the subject or body of the message).
Further Protection
Obscure Addresses
If you use common email addresses (especially hosting companies) such as support@ or contact@, you will receive more spam. This is due to spammers blindly emailing these addresses on several domains. If you use less-common addresses, it may reduce your level of incoming spam.
For example, you could use:
- helpme@yourdomain
- support-team@yourdomain
- assistance@yourdomain
