Is there a character limit on the Addresses Discard Filter in the mailbox configuration?
Oracle B2C Service
There is a 4,000 character limit to the Addresses Discard Filter in the mailbox configuration of the CX application, and this field currently cannot be extended to additional characters. However, please note, you can use an asterisk (*) as a wildcard to match any characters. For example, to discard all email from 'firstname.lastname@example.org' and all 'example.org' addresses, type: 'email@example.com,*@example.org'. You might also want to review any commonalities in the email addresses to reduce some characters.
There are several other options available to filter email addresses in order to prevent Spam. It is highly recommended to use the blocklist feature in the Spam filter as the feature is the same as the Discard Addresses field that is configured for mailboxes within your CX application. You also might be able to create a business rule using something similar to:
IF certain keywords in the email address = <'value'>
THEN 'Do Not Create Incident'
See Answer ID 11713: Managing the new Spam Quarantine and Answer ID 908: Preventing spam/junk email from becoming incidents for further information on Spam filtering and configuring a rule to manage your emails.
