UCE: Part 3 – SORBS issues are on-going

Having previously posted concerning this and related topics, I just wanted to provide an update and let you know that the issue with the incorrect classification of IP ranges for a particular ISP by SORBS is ongoing. SORBS has yet to turnaround our request, and it has extended beyond what they consider a “reasonable” 2-15 day turnaround.

This has been a particularly difficult issue to get any traction on, as it’s next to impossible to engage SORBS, either directly or though the ISP (which has been very cooperative).

For each affected customer, we’ve started forwarding email traffic through the ISP’s SMTP servers, and this has proved to be a an effective workaround.

If and when something changes, I’ll post with the details.
