The error is from your providers SMTP server. Web mail does not use that server. Thunderbird does not run on phones or tablets. Simple deduction says this is not a Thunderbird issue.

Contact your provider and tell them the error you are getting. Clicking the link indicates that you provider is blacklisted due to spam or other inappropriate content.
