Black List

[jtsai8585]

Does dash "-" have special meaning in Ironport black listing domains?  (Hat Overview => Sendergroup (blacklist) ) ?

Such as i put in   " .bad-email.com".    Will the dash email cause issues or it will match that domain exact?

Thanks.

Hi,

The entries in HAT sendergroup match the sending server IP/FQDN. Domain is only checked after HAT using message filters, incoming/outgoing mail policies etc.

The hyphen "-" should not cause any issues with matching the hostname of the sending server.

Thanks.  I would assume that it's not using regex in adding domain name.

I do not think HAT supports regex currently.

The following formats are allowed:

• IPv6 addresses such as 2001:420:80:1::5
• IPv6 subnets such as 2001:db8::/32
• IPv4 addresses such as 10.1.1.0
• IPv4 subnets such as 10.1.1.0/24 or 10.2.3.1
• IPv4 and IPv6 address ranges such as 10.1.1.10-20, 10.1.1-5 or 2001::2-2001::10.
• Hostnames such as example.com.
• Partial hostnames such as .example.com.
