1374120 - authentication error with gmx.fr account because ISP setting "«POP3/IMAP functions» to authorize e-mail clients" not enabled

Status: UNCONFIRMED

(Thunderbird :: Account Manager, enhancement)

Description

[polo]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:52.0) Gecko/20100101 Firefox/52.0
Build ID: 20170613225334

Steps to reproduce:

I just created a gmx.fr account and I tried to setup thunderbird with it.
I use thunderbird 45.8.0 on debian testing (stretch) 64 bit. Same problem on an ordissimo (it's a PC for «old» people with a debian based distrib with very simplified interface).


Actual results:

I had this message in french:
«Échec de l'envoi du nom d'utilisateur. Le serveur de courrier pop.gmx.com a répondu : authentication failed»

Same problem with POP3 and IMAP.

Yet all parameters was correct (adress, password, name of account, POP, IMAP and SMTP servers, port number). Changing server parameter changes nothing.

I teared my hair out and ask my search engine. In fact, e-mail clients was blocked by default, except the android and iphone app. User must connect in the website and tick a box in «settings» => «POP3/IMAP functions» to authorize e-mail clients.


Expected results:

Thunderbird could anticipate this problem and inform lost users, for exemple with a link to this page:
