A note to friends who also read this blog: I have had an email problem.
While on the road this weekend, my internet provider changed outgoing server settings. Result: I could not send anything out.
It took a while to get things going, since on the provider’s website there was conflicting information on different pages. I called support for a clarification but got someone about as smart as a box of hammers, which resulted in lost time.
To make a long and irritating story short, friends, my email is working properly again.
