I have created a custom rule to allow an email address or domain through but it is still being blocked.
This article shows why creating a custom rule can sometimes not be enough to allow an email address or domain through Kerio Connect.
Creating a custom rule to allow an email address or domain through Kerio Connect on some occasions cannot be enough. A common problem with this is that the email address or domain you are trying to ‘whitelist’ by creating a custom rule is also on an internet blacklist. By default Kerio is set to block any email traffic that is on a blacklist that has been enabled. The way around this is to do the following:
- Check the spam log to see which blacklist the email address or domain is being detected on
- Then once you know which blacklist the email address or domain is on you will need to go to Configuration > Content Filter > Spam Filter > Blacklists
- Double click on the blacklist and change the option from ‘Block’ to ‘Add spam score to message’ (You can set the score to a value you see fit or you could make it equal to your block score set in the spam filter so that the blacklist will still block other spam)
- Then click ‘OK’ and apply the changes
The reason for changing the blacklist to add a score to the message instead of blocking is because the spam filter checks the blacklists before the custom rules. By setting the blacklist to add a score it allows the rest of the filtering settings to check the email.
