POP3 error message with Thunderbird and Internet Security 5.0.507

[GSW]

Hi
I get an error message:
Translated from Swedish: "An error occurred at the server for incoming messages (POP3). The E-mail     \
server mail.indell.net responded:"

It makes it impossible to get any email messages from the server to my computer.
I've read another post about a problem that looks like this, but in that case it was about SSL and TSL.
In my case I have "Use Secure Authentication; Never", so it must be another problem.

The problem occurred after I hade installed Internet Security instead of the free version of Avast.

Anybody who can help?

Problem solved.

Internet Security had made my connection a secure SSL connection and changed the port to 995.
When I changed to "none" in Encryption and to my ordinary port the mails started coming again.

2 days of work to get it to work again after updating.

Hope it will help someone.
