Dear

Subject to the following mail addresses: gunter.peeters@scarlet.be

We keep getting the following message when sending emails. An error occurred while sending email. The mail server replied: ip 213.49.30.104 blocked for relaying spam http://www.scarlet.be/pm/?e=f53&s=r&p=213.49.30.104. Please check if your email address is set correctly in your account settings and try again.

We are able to receive emails.

Is it possible to check this out?

Thanks in advance!

Kind regards Gunter Peeters

Dear

The previous notification, after a scan, has disappeared. However, we are now getting the message below: Message sending failed. The outgoing (SMTP) server smtp.scarlet.be does not support the selected authentication method. Change the 'Authentication Method' in the 'Account Settings | Outgoing Server (SMTP)'.

If we select 'no authentication' in the account settings, it does work to send mails. However, this is not secure.

What can be done about this?

Thanks in advance!

Scarlet indicates the outgoing server should be smtp.scarlet.be, port 465, SSL/TLS, authentication = normal password, User Name = email address.

Have you tried those settings, and if you have multiple accounts, is the scarlet account sending on the correct smtp, with a matching User Name?

We have two accounts. If we change the username in the first account, the username of the second account is automatically changed with the username of the second account. This was not the case before. How can we change this?

Thanks in advance for the help.

Best regards

You should have separate smtp servers for each account, and make sure each account is sending on the correct smtp:

It has succeeded several times. Now again it has not. Following problem: Message sending failed. The message could not be sent because the connection waiting time to outgoing (SMTP) server smtp.scarlet.be has expired. Please try again.

Yesterday we managed to send emails using the above tips. We tried this again this morning and got the below message again: Sending message failed. An error occurred while sending email. The mail server replied: ip 213.49.30.104 blocked for relaying spam http://www.scarlet.be/pm/?e=f53&s=r&p=213.49.30.104. Please make sure your email address is set correctly in your account settings and try again.

The email addresses are still set as they were last night.

Best regards

An error about possible spam is separate from the issue of having the correct account settings. It means the mail server of the recipient is blocking mail from your server due to alleged spam content. There can be several reasons, but it's best you contact your mail service provider as the problem is not caused by TB (or any other mail client). If your messages contain several links or remotely-hosted images, perhaps included in a signature, that can trigger spam filters at the recipients' server. See if the same error shows when you send a plain text test message without a signature.

As for the 'server expired' (timeout) error, that can be caused by antivirus that scans outgoing mail. If the antivirus is not MS/Windows Security/Defender, set your antivirus to not scan the TB profile folder or outgoing mail or secure connections. Better, if it's something like Avast/AVG/Norton, remove it and use the built-in Windows AV.

Thank you for this info. We only use 'Windows security' and still we keep getting this message.

The problem just doesn't get solved. Now we cannot send mail with either mail address.

We get the following messages:

  • Login to server smtp.scarlet.be with username iris.wouters@scarlet.be failed.
  • Sending message failed.

Cannot authenticate to outgoing (SMTP) server smtp.scarlet.be. Please check the password and verify the 'Authentication Method' in the 'Account Settings | Outgoing Server (SMTP)'.

Kind regards

It appears you can send mail sometimes, so I don't think there's an error in the TB configuration. Are you using a VPN? That could cause authentication errors. Try with Windows running in safe mode to bypass any startup apps that might be interfering.
