You might want to look at moving to MailSite:

We have many customers that have moved from Post.Office. We value our customers
and offer very reasonable upgrades.
>The pricing is simply ridiculous. We like Post.Office 3.1.2 very much. But,
>at that sort of price, there is no way we are going to even consider
>upgrading. Most vendors give their customers free, or very low cost,
>upgrades within version types. Apparently Software.com doesn't think this
>way, and doesn't care about customer loyalty. This pricing structure will
>drive customers away in droves.

>On the other hand I must admit that the Postoffice E-Mail server works

>>pricing strategy of software.com is becoming a problem for us.
