emails sent on thunderbird post update 102.14.0 being blacklisted

I updated to latest version of Thunderbird 102.14.0 on 4th August and thereafter all emails being sent by me are being blacklisted by spamhaus.

When i put in a request to Whitelist, it changes for some time and again all mails sent from my inbox are getting blacklisted. The message which i get is as under:

"Your IP address is either exhibiting suspect behavior, is misconfigured, or has a poor sending reputation.

As a result, the IP is listed in the CSS Blocklist (CSS)

Click on Show Details to see if you can request a delisting from this blocklist. This will also display any further information we have relating to this listing."

We have checked with our internet service provider, my email server works perfect. We have checked with ISP there is no problem there too as my colleague uses same network but different mail (outlook) works perfectly.

Please help as I am unable to use Thunderbird for sending emails. While I can receive emails.

regards Vineet

I'm sorry to hear about the trouble you're facing with Thunderbird after the recent update. It sounds like your emails are being blacklisted by spam filters due to some suspicious behavior from your IP address. To resolve this, you might want to check if your IP address has a good sending reputation. You can try contacting your email service provider and see if they can provide any insights or help with delisting from the CSS Blocklist. Additionally, you could consider reaching out to Spamhaus directly for further assistance. It's also worth confirming that your Thunderbird settings are correctly configured for outgoing emails. If all else fails, you might consider using an alternative email client temporarily until this issue gets resolved.
