The following Senders can be added to safelists and blocklists using the following formats:
user@domain.com
server.domain.com
domain.com
[10.1.1.0]
[ipv6:2001:DB8:1::1]
user@[1.2.3.4]
To safelist a partial domain you can add it to the whitelist to bypass Antispam scanning or create a new senders group in the HAT to bypass sender base reputation checks.
