hi There, thank you for your help. I believe I have set up ssl on my PHP server but I am not sure how to check this. I have tried to input ssl://smtp.gmail.com to force ssl but after I have saved it and return to the global parameters page I see only this smtp.gmail.com. I have pasted an excerpt from the log in the hope that it helps. Please can you point me in the right direction?
