Question
How to prevent an email from being filtered?
Answer
By configuring a white or black lists filter rule for outgoing or incoming filter the emails in the configuration will be accepted or sent without the need for the filter to check it.
This is very useful when there is an abuse e-mail address that for example should receive all e-mails.
In this case, add abuse@yourcompany.com to the recipient white list.
The steps for the configuration can be found on the follow URLS of Spamexperts knowledge base for the incoming and outgoing filter rule.
