Decided it was time I arranged to access my emails via my phone. It's a PAYG, so will only do this when I have a Wi-Fi connection, which is fine for me.
I have basically two email accounts. My BT one which I hardly ever use the POP side on - but do use the SMTP side for sending.
The BT one was easy to set up on the phone and works.
My other ones is my own pop box at 123-reg
As well as the @davesound email address it has what this ancient email prog I use here calls a 'remote user' as well as the normal password and server.
On this email prog I'm getting the details from on this computer, with the BT settings, the 'remote user' is the same as the email address. But different with the 123-reg one.
