HPop 1.2 for Mac could be downloaded from the developer's website when we last checked. We cannot confirm if there is a free download of this app available.
Please check the Mac app with an antivirus before launch as it is downloaded from the developer's website, and we cannot ensure that it is safe. This software for Mac OS X was originally designed by HSoftware. The program lies within Communication Tools, more precisely E-mail.
From the developer:
HPop is a POP email checker with filter actions. You can add multiple accounts and apply filters to each mail. For example, the emails can be stored in a file to do a later process like adding emails to a database. Also, you can delete ane mail without downloading it.
You may want to check out more Mac applications, such as Zimbra Toaster, PageSender or Mail to ToDo X, which might be similar to HPop.
