"cannot connect to the mail server to verify your account information, your server is not responding"
Hi, I was advised by my ISP to use their details to receive incoming email (pop) and to use my mobile phone provider's details for outgoing email (smtp).
E.g., Incoming: mail.velocitynet.com.au
You will need to use your username and password.
Outgoing: mail.bigpond.com
There's no need to change any of the settings other than unticking the tick box.
