Callbox Sales and Marketing Solutions

I didn’t receive this one myself. Instead, I noticed it on the Spamhaus Blocklist “Lastest SBL Changes” page.

Looks like a company called “Callbox Sales and Marketing Solutions” is trolling for B2B leads and it attracted the attention of Spamhaus, who has now listed the source IP on their SBL. The ESP is Streamsend.
