I have moved from one server to another. It is not good to have a naively trusting faith in everything having gone according to plan and being trustworthy. My initial answer is NO, I have not touched anything, including the smtp server, and I have also not updated the username,password,or port, but who knows what might have happened in the transition. So please let me check.
I will be back directly with what information I can about the mailserver settings.
But in the mean time, I think it best I put another issue I have discovered in its separate posting.
