Eudora email client: does anyone know it? Problem!

Hi,
I have some accounts gmail.com and all work fine with Eudora 7.1.
Recently my NOT gmail.com email stopped working and now I had to change it. So I thought of choosing gmail [email protected]. But Eudora gives me ERROR when I try oo do the "check mail". I attach a photo.I don't understand why, since on the gmail page on the web I configured it in POP3 and the other gmail accounts work fine with Eudora 7.1. And yet I configured this new gmail account perfectly the same as the others. Maybe in Eudora do I need to choose "SSL" in the configuration? But I don't know how to do it because there are wrong steps on the Internet. I would like to continue using Eudora because it has the ability to configure the Layout.
Thanks for some info.

Outdated Encryption: Eudora 7.1.0.9 and earlier do not natively support modern SSL/TLS 1.2 or 1.3. Many modern email providers (like Gmail and Outlook) now require these protocols, meaning Eudora often cannot connect without unsecure workarounds like stunnel.
Lack of Modern Authentication: It does not natively support OAuth2, the current industry standard for secure logins. Using Eudora with many providers requires enabling "less secure apps" or using app-specific passwords, which increases account takeover risks.
No Security Patches: Development ceased in 2006 (mainline) and 2010 (OSE). Any vulnerabilities discovered in the last 15+ years remain unpatched, leaving the software open to exploits like buffer overflows or malicious code execution through email attachments.
Outdated Certificate Store: Eudora lacks a modern root certificate store, meaning it cannot verify the safety of modern websites or mail servers.

There's no doubt that what you say is true, but then why
1) Do the other 3 old gmail.coms work? Only the new one doesn't work, maybe because I have to configure something.
2) Why if I test this new account with Eudora do I see that everything is OK?

Perhaps the old ones were configured when you could still go the 'Use less secure apps' route.
Happened to me.

Maybe you're right. In fact, I no longer see this line on the Google portal: 'Use less secure apps'.
Have you removed it recently?

A long time ago.

I also had Opera Mail for the longest time, ages ago..., same thing!

Hi,
since Eudora doesn't work anymore, I'm trying Thunderbir, so I transferred the emails with "ImportExport Tool". The emails that are transferred from Eudora to Thunderbird are mixed up with the ones I deleted.I'll give you an example: if I get some propaganda email, I delete them as well as the messages that come from the forums that say: there's a response to your post.In fact, the messages transferred are too many, 2500. And only those messages that I had deleted do not have the subject, but only the title. So I have a lot of confusion of messages.In "ImportExport Tool" I used "Import individual mbox files". What does "Import individual mbox files with sbd structure" mean? I hope I have chosen the right option for importing emails.
Maybe I need to configure "ImportExport Tool"?
Thank you.
