Expiration

A listing is automatically expires after a certain amount of time if no more malware comes from a host.

The exact expiration time depends on many factors, such as:

• How important is that host to Hungarian mail servers
• How long it has already been listed before
• How many times it has been relisted
• How many malware we get from it
• How many listed hosts reside in its subnet
• And others

The expiration times are not made public.

Hosts can be manually delisted prior expiration, but they get listed again if their behavior doesn't change.
