Telus IP address blocked due to AUP violation on SMTP client.

Hi, I'm trying to troubleshoot an issue where a residential family member using Telus Internet can't seem to send smtp emails through Thunderbird on a Windows PC.  The user has a Shaw.ca address and can receive emails, but recently started getting the following error when sending mail:

I checked the IP address and it shows on Spamhaus's PBL.  The SMTP mail settings show he's using STARTLS auth with a username/password and I don't see any compromise of the PC.  I suspect there's an IP in that range that was actually compromised as shows on SpamHaus:

"66.222.208.0/20 is listed on the Policy Block List (PBL)"

Is there a way to get Telus to get this Ip off the list, or is there a way to get a new IP address?  The DHCP release on the router and shutting off for 10+ hours didn't work.  

Thanks.

    I believe that Telus restricts From addresses to their domain for SMTP relaying. If they are sending from a Shaw.ca address they will need to use the Shaw SMTP server to send with that address. I would check the Thunderbird settings for their Shaw.ca account to ensure it's properly configured to use their SMTP server.
