I am so sorry if i speak english in your forum, i really hope you can help me this way.
Thank you very much.
I arrived 2 days ago in Germany and being trying since to fix my problem.
I am staying at a friend of mine for a while.
He has Alice at home.
I am unable to send emails with thunderbird.
I usually travel with my laptop and ask the smtp connection from the provider of the place where I am loggin in but this is the first time I am having trouble.
I have different email accounts from the domain of the work place and other domains I use, something like
I can download the emails no problem, but when trying to send an email with the Alice smtp configuration it does not allow:
An error occurred while sending mail. The mail server responded: 5.7.3 Client does not have permission to Send As this sender.. Please verify that your email address is correct in your Mail preferences and try again
Then it says
Sending of message failed.
The message could not be sent because connecting to SMTP server smtp.alice.de failed. The server may be unavailable or is refusing SMTP Connections. Please verify...
I have followed all istructions at Alice.de
I also created and tested 2 thunderbird accounts with the credentials of my friend
One Pop and one Imap
User Name: email@example.com
Server Name smtp.alice.de
Secure connection: works with "No" and TLS (if available)
I am able to SEND and receive emails from firstname.lastname@example.org account
but when i use the same smtp server for the outgoing mail of the other domains, I receive the answer i mentioned before
Please, does anyone know how to make Alice send messages from other emails of different domains.
Thank you very very much for your help.
