Yes, but subdomains that deliver to different locations are treated as separate domains and you must purchase service separately for each subdomain configured this way.
Can I whitelist or blacklist certain email addresses?
Yes, once you sign up, you'll be able to log into your anti-spam account and set up white or blacklists as needed. Each email user can have a separate white or blacklist or you can assign certain global white or blacklisted addresses globally to all email accounts.
Can I import white or blacklists from another service like Spam Assassin?
You can add the same addresses to our white or blacklists as you have set up in another service, but you probably don't need to do so.
Our mail filtering service is far better than what you may be using now (like Spam Assassin), so while other services may need carefully tended white or blacklists to work properly, ours shouldn't. You should only blacklist email that isn't spam, but which is something you know you don't want (for example, mail from someone you never want to talk to). Whitelisting should only be needed if you want to be extra certain that no mail from that address or domain gets filtered as spam.
There is not currently a way to mass-import white or blacklist items from another service, though you can export your white or blacklist as a CSV file if you want.
Does incoming mail filtering cause SPF record issues?
