Login to the server pop.gmx.net with username "..." failed.
I have several accounts with GMX. Two work, and the other two display the above error message. Everything works when I log in via a browser, but not in Thunderbird. The account settings are identical for all four accounts except for the password and username.
What can I do?
Thank you in advance.
