Have you tried the settings that I shared?

@Rick! Good news, finally they managed to get me in. But now I am confronted with a configuration I have never seen before.

This was cPanel before but somewhere along the road they changed to hPanel which I am not really familiar with. It's supposed to be easier but I find it harder. What am I supposed to change or add in the attached image?

There's one other thing I noticed. Thunderbird assumes automatically that the server is IMAP while in Eudora it's POP, I wouldn't know how to change that

I wrote a long response that has not been posted. I do not know if it is being held for moderation. I will look for it on my computer later.

I'll try again.

What am I supposed to change or add in the attached image?

I do not know what, if anything, you should change in the zone records. I'm assuming, at least for now, that they are correct. But I would like to see your MX records. Would you please use either cPanel or hPanel to show your zone records (as you did in the screen image), select MX records, and either share them in a screen image or type them?

Do you have reason to believe that you should change something in your zone records?

Our task from the beginning has been to ensure that Thunderbird is using the correct information for your incoming and outgoing servers. David suggested sharing that information right away, and I have asked you for that information twice. Would you please share the following information?

INCOMING SERVER Look in account settings > Server Settings. Server type: Server name: Port: User name: Don't share. Just make sure that it is your full e-mail address. Connection security: Authentication method:

OUTGOING SERVER Look in account settings > click on account name > click on "Edit outgoing server". Server name: Port: Connection security: Authentiation method: User name: Don't share. Just make sure that it is your full e-mail address.

finally they managed to get me in

Who or what managed to get you into what?

Thunderbird assumes automatically that the server is IMAP

Are you saying that an IMAP account in Thunderbird is receiving and sending messages? That would be very good news.

I can help you set up a POP account in Thunderbird. Please don't try to change your IMAP account. You have to create a new account in Thunderbird, set settings, and save your IMAP messages. Then you can delete the IMAP account and use just the POP account.
