Hello, I have a problem with my account. When I created my account, I was given the name "541225629" and the password "0600806936". This account is functional and I can open a Webmail box in it. When installing the email application "Mozilla thunderbird", an account zmrzlys@iol.cz was created with the password "up5Date" entered. I will not open a Webmail box for this password. I have been using this account for years without any problems. Recently (probably after an update), however, when starting thunderbird, a password for "zmrzly pop3. Iol.cz" is requested. None of the passwords saved for "iol" are accepted. POP3 responds with [AUTH] Authentication failed. After ignoring this request (X), the mail works. When trying to find a valid password on the website, I received the following answers: "Zmrzly account error - sending the password for the user "zmrzly" was not successful. POP3 iol.cz responds [AUTH] Authentication failed. When trying to log in or create an account at "centrum" - zmrzlys@iol.cz indicates an incorrect e-mail address. When creating a new account "zmrzly" the address is taken. Please help with the solution Thanks to Ing. Simon Zmrzl ýCSc.
