Hello, I have updated from civicrm 2.0.1 to 2.0.3 and I have solved some problems but when I´m trying to send an email I receive the next message:


" A fatal error occurred when CiviCRM attempted to send an email (via SMTP).
If you received this error after submitted on online contribution or event registration - the transaction was completed, but we were unable to send the email receipt.


This is probably related to a problem in your Outbound Email Settings (Administer CiviCRM » Global Settings » Outbound Email). Possible causes are:

    * Your SMTP Username or Password are incorrect.
    * Your SMTP Server (machine) name is incorrect.
    * You need to use an Port other than the default port 25 in your environment.
    * Your SMTP server is just not responding right now (it is down for some reason).

Check this page for more information.

The mail library returned the following error message: authentication failure [SMTP: Authentication failed.
(code: 221, response: smtp.1and1.es Bye)] "

Before I updated it, the e-mails were sent correctly, anyway I have reconfigurated my email setting and I have the same error.
What is the problem?
I have this problem for two weeks now and I can´t solve it. This is the reason why I wrote this post: http://forum.civicrm.org/index.php/topic,3677.0.html
but it´s not the best solution.

thanks

Thanks for your reply Dave.
1and1 says me that they can´t give me the logs. I have configurated Mozilla Thunderbird and I can send emails and I have installed a new  local civicrm and I can send emails.
