Hello forum,
I am using K-9 Mail v6.804 on a Samsung Galaxy S23 with Android 14.
Sorry, but as a new user I had to replace @ with at
Long time ago I registered an e-mail adress at arcor.de with 3 alias adresses.
This was the reason why I choosed K-9 Mail years ago.
Since a couple of years Arcor was taken over by Vodafone so the new e-mail adresses are “_at_vodafonemail.de” but the older “_at_arcor.de” still work fine.
I am using 4 different Mail accounts, all set up as IMAP-accounts.
The other three work fine, except this arcor/vodafone account.
Since maybe 4 weeks or longer I tried to send a message via this arcor account and received the error messages:
- Messages can not be sent. Error: authentication failed
- Authtication failed. Check your server setting
So I checked “Settings - Send e-mails - outgoing mail server” and saw:
Server: smtp.vodafonemail.de
Security: SSL/TLS
Port: 465
Authentication: Normal Password
Username: myname_at_vodafonemail.de
Password: hidden
Client-Certificate: None
Of course this will lead to an authentication error because the username had to be myname_at_arcor.de.
I can change the username and check the server settings via continue-button but I still receive the authentication error.
If I close server settings and enter them again, the username ist set to myname_at_vodafonemail.de
On my PC I can still send e-mails with this accout.
Is there any chance to get it working again?
