Is there an email client you recommend, other than the default Ecohost webmail?
Using a native IMAP client (email program or mail user agent) on works far better for them than web-based. For example Thunderbird which is popular free and open source software available for Windows, OSX and GNU/Linux. Or if you are on Android, K9 Mail.
The settings you will need are to configure your email client are documented on this site.
