and Open Technologies has updated Post.Office, their mail server and list server for Mac OS X, to the oddly numbered version 3.5.3 version 711. The update offers enhanced spam filtering and IMAP support.
Post.Office is an SMTP/POP3/IMAP messaging server developed for small and mid-sized Internet Service Providers, which can be administered using a Web browser. It doesn’t run with root privileges and operates independently of the host computer, which Tenon said makes it impossible to compromise the main system security via e-mail.
The update also offers more sophisticated header and message body-based regular expression filtering to let postmasters more effectively manage unwanted e-mail. The new package includes sample spam filters, which are created using Post.Office’s Web-based GUI (graphical user interface). Also included are scripts to import user account information from a range of mail servers (such as EIMS, SIMS, WebSTAR mail). If user account information can be exported into a text file, Tenon’s script can import the accounts into Post.Office. Also, lists from LetterRip can be imported into the Post.Office list server.
Post.Office is licensed on a sliding scale, with a starter package available for US$295 that supports 100 mailboxes and 10 lists. Packages are available for universities, corporations and ISPs as well. A free version of Post.Office, limited to 10 mailboxes and two mailing lists is downloadable from Tenon’s web site.
