Utility to import Squirrelmail address book into Horde and Roundcube
As a web-hosting provider, I would like to have a feature that imports Squirrelmail’s address book into Horde or Rouncube so this happens automatically instead of manually.
As we all know, Squirrelmail is deprecated and will be removed as of WHM 78. Many companies have a lot of customers still using Squirrelmail. The Squirrelmail address books aren't automatically exported from Squirrelmail and into Horde and Roundcube. In fact, there is no direct facility in Squirrelmail to export an address book.
My suggestion is that cPanel import the Squirrelmail address book into both Horde and Roundcube as part of their Squirrelmail removal process in WHM 78. Or, at the very least provide an easy-to-use utility that allows admins and users (via the cPanel interface or the Webmail main screen) to import their old Squirrelmail address book into both Horde and Roundcube.
People using Squirrelmail have probably used it for years and likely haven't even bothered to try switching to Horde or Roundcube. As such, they are likely to have substantial address books in Squirrelmail that they will never see once Squirrelmail is removed, unless the Squirrelmail removal process automatically does it or a utility is added to a customer-accessible interface whereby they can choose to import the Squirrelmail address book into one or both of Horde and Roundcube.
