Can´t send e-mails with Thunderbird, all settings from my provider are right. I called my provider, they didn´t change a thing. I can send and get e-mails over the web-mail account, but can´t send mails over thunderbird (but I get e-mails). Password reseted, Firewall and Antivirus (Avira) deactivated - but no result. Mail Server answers: 5.7.1 Rejected due to from vs authenticated sender inconsistency. Check your mail and try again.

There's a mismatch between the sender email address of the message you're sending, and the user ID for your provider's SMTP server. Fix that. It's not a Thunderbird problem.

Thanks for the answer, but the provider confirmed the settings I sent with the jpeg. Everything worked until yesterday!

When you try to send email using 'Write' window, look at the email address you are using in the 'From' section. Q: What comes after the '@' sign in your email address?
