Requirements

PHP 4 or higher is required, but PHP 4.2.0+ is recommended. PHP must be compiled with at least the --with-imap command (whether using IMAP, NNTP or POP3 support).

In addition, the following flags are needed for optional features:

--with-imap-ssl for IMAP/POP3 over SSL
--with-db for Sendmail virtusertable support
