Problem
How is the priority of Whitelisting vs Blacklisting handled for VadeSecure?
Solution
The more specific entry wins. In case of a blacklist entry for a domain and a whitelist entry for a specific address of this domain, everything will be blocked except the specific whitelist address.
Example:
- Domain is whitelisted
- Specific address is blacklisted
A match against the blacklist entry wins in this case. If the same entry exists in black and whitelist, the whitelist entry wins.- Regarding other checks, the whitelist is applied on the RCPT TO step. All protocolar rules applied before are not subject of blacklist/whitelist. The protocolar rules concerned are as follows:
HELO : check if the HELO is a FQDN |
