Next month Google will shut down Postini and retire the program. We are rolling out Antispam Pro as a replacemant for Postini's anti-spam email filtering service. Through the week of Monday, April 22, until Friday, April 26, we will be activating Antispam Pro on all domains that currently have Postini enabled. We will disable all Postini accounts on Monday, April the 29th to prevent mailboxes from breaking when Google shuts down Postini services. You will need to manually recreate your whitelists and blacklists in Antispam Pro, so if you need to reference your Postini filter settings please do so before the 29th of April.
Antispam Pro provides the same service that Postini did, but gives you a chance to save money as well. Where Postini was billed by the mailbox, Antispam Pro is billed by the domain. So you can apply Antispam Pro to as many mailboxes under the same domain without any extra charge. Pricing will be $2.50 per month for Reseller accounts, and $3.00 for Shared hosting accounts plus the MX custom DNS record fee associated with certain accounts. New features such as outgoing mail filters and email archiving are also expected to be offered. Details will be coming soon.
