We have written a Knowledge Base article on how to setup a new account with Mozilla Thunderbird which can be read on our support portal at https://www.redit.co.uk/support/index.php?act=article&code=view&id=6
If you would like to change to secure eMail using our service please let us know so we can write a guide on how this is done, we plan on having the guide on changing within Thunderbird completed by the end of today (Wednesday 8th July 2015)
