Thunderbird 148.0 no longer connects to SMTP server hostrocket.com
I have spent most of two days trying to Thunderbird to send email. It has worked perfectly for years. Suddenly, emails end up in Sent folder but go nowhere. My email host service sees nothing wrong. I can send emails through webmail and usually through Outlook. I have spent most of the day getting coached by Copilot and I am quite sure I have all the settings the way that worked flawlessly until two weeks ago. Is Thunderbird just dead and I need to go to Outlook?

First, you have provided no details that allow someone to investigate this. I suggest posting a screenshot of the SMTP server settings pane, plus screenshot of any error message. Please also provide detail on what you mean by the messages being in Sent folder, yet going nowhere. Thank you. I do not mean to imply that I have the solution; I only mean that nobody can assist without more information. thank you

If I look in Sent, I see the message that I sent to myself, but it does not arrive in my inbox either in Thunderbird or webmail or Outlook.
Curiously, it does not send from Outlook either.
Is this an IMAP account? If so, I suggest checking the sent folder from your online account to see if it is there. That would be helpful.
IMAP. From webmail, I can see the email in Sent folder..
Thank you. That confirms that Thunderbird is working. The fact that it does not appear in inbox is because 'something' is discarding the email, possibly your email provider. Depending on the email host, an error message may be returned to sender or the message may just be deleted. That is what is happening to you. You will not resolve this from Thunderbird, as it is doing what you ask. You might try sending test messages to friends who use different email provider. I suggest that because another email host may accept or send useful error message. I wish you well in this.
To add more info, it may be that your IP is blocked, your mail looks like spam, or that the email host doesn't like your settings. I have no idea on what the true reason is.
Thank you. This provides evidence that Thunderbird is working,

There is no Dmarc, so that will cause Google Yahoo and Outlook delivery issues. See https://mxtoolbox.com/SuperTool.aspx?action=dmarc%3aclaytoncramer.com&run=toolpage
SPF and DKIM are very important in mail delivery these days and cheapest providers generally do not do well in complying.
