>&#13;        Webmail IMP allows universal, web-based access to <SPAN
CLASS="acronym"
>IMAP/POP3</SPAN
> servers and provides an address book, <SPAN
CLASS="acronym"
>LDAP</SPAN
> directory searches, full support for sending and receiving attachments, and
        many other features normally only found in desktop mail clients. If you have installed Apache with <SPAN
CLASS="acronym"
>SSL</SPAN
> support, clients can access and read mail through a secure manner by way of <SPAN
CLASS="acronym"
>SSL</SPAN
>
        encryption. By default in this section, we have configured Webmail <SPAN
CLASS="acronym"
>IMP</SPAN
> to use PostgreSQL database and <SPAN
CLASS="acronym"
>IMAP</SPAN
> connections. There is, though, much support for other databases within Webmail IMP. If you prefer, you can use MySQL, Oracle, Sybase, or other well know SQL databases. You may also choose to use POP3 instead of IMAP connection to your clients.
