Email - broken links, substitute characters?

[Juscommune]

I am setting up a Word Press site and have installed a plug-in which uses osTickets (I'm assuming it is the latest version)

When running a test the recipient receives an email which has broken links and some characters like the @ symbol being replaced with: %40

Carriage returns have an equals symbol etc.

Does anyone know what needs to be done to correct this? - sample of email below:
