@krypton No, I actually was not aware of that. I tried for quite some time to figure out what I did wrong, and it didn't say that anywhere. I also didn't expect something like this, as normally the password for the webinterface and imap is the same. Thanks for pointing that out, I changed the imap password and it works just fine now.
hi, I am trying to sync my bluewin email account with a client, namely GNOME Evolution (but that should not matter). Even though the settings are (kind of) mentioned in , the connection breaks with the error message "Failed to authenticate: IMAP server said BYE: disconnecting". I tried all possible types of encryption and authentication, but none of it seems to work. Interestingly, I can't get it to work with Mozilla Thunderbird as well, whereas it works just fine with MS Outlook (which I do not have access to). my settings (IMAP): - Server: imaps.bluewin.ch - Username: (the one I use for the webmail) - Port: 993 - Encryption Method: TLS - Authentication: Password The passwort is correct, I checked it.
