For the 4th in less than a year, my Thunderbird email is denied outgoing mail service, with an error message saying: An error occurred while sending mail: The mail server sent an incorrect greeting: 5.7.1 RBL Restriction: https://www.spamhaus.org/query/ip/216.228.169.64. My ISP insists this is a Thunderbird problem because I can still send emails using their lousy webmail program. I can still receive emails with Thunderbird. When checking the Spamhaus site, I learn that my IP address has been blacklisted on CBL for spam resulting from the "Conficker Worm." However, I've had my computer screened and cleaned, I maintain full level protection using Kaspersky, all devices get scanned before use whenever connected to my computer, and my wireless router is fully WPA-2 protected. Further, Conficker is an old worm easily detected by all modern anti-virus programs. I can still use Thunderbird whenever I'm operating from another wireless device but not at home. My ISP insists that the only solution is for me to shut down my wireless router for more than 48 hours, then turn it back on to receive a new IP address. This has worked but isn't really a good solution for me and it releases the old IP address to get picked up by someone else. Is there something in Thunderbird that contributes to this issue?

O.K. I followed those instructions. Do you need more than what is below?

You ISPs lousy web interface is probably indicative of a greater malaise.

You are sending mail using smtp-server.bendbroadband.com that this srvice is blacklisted by spamhaus is directly your service providers responsibility.

Why does their lousy web service no suffer from the issue? They treat it differently. Looking here I see that the registered mail exchanger for their domain is mx.tds.net. But there are issues with the domain A record. 

Malformed greeting or no A records found matching banner text for following servers, and banner is not an address literal. RFC5321 requires one or the other (should not be a CNAME). If this is not set correctly, some mail platforms will reject or delay mail from you, and can cause hard to diagnose issues with deliverability. Mailserver details:

64.8.70.104 | WARNING: The hostname in the SMTP greeting does not match the reverse DNS (PTR) record for your mail server. This probably won't cause any harm, but may be a technical violation of RFC5321

Basically they need to get their act together and learn how to provide a reliable modern mail system. What they have no has multiple issues. Perhaps if you give them a link to the issues they are capable of fixing the worst ones.
