Thunderbird Send and receive email

Hello!

For the past few days, I have been having problems with my Mozilla Thunderbird email program. I can receive emails, but I cannot reply to them or write and send emails myself.

When I try to send a mail, I get the following message:

The message failed to send. Error sending the message: SMTP server error. The mail server responded: IP=212.103.61.109 – Your address is blocked.

Can anyone help me? That would be really great!!!

Thanks in advance.

that ip address is listed on mxtoolbox.com as a sender of spam. https://mxtoolbox.com/Problem/Blacklist/s5h.net/?page=prob_blacklist&ip=212.103.61.109&link=button&action=blacklist:212.103.61.109&showLogin=1&hidetoc=1&reason=127.0.0.2

According to mxtoolbox, you can have it delisted here: this is not related to choice of email client.
