Hi,

Just over two weeks since I found myself on Microsoft's blocklist and was manually removed, I find myself back on their blocklist again. Possibly coincidentally, this morning MXToolbox informed me that Linode has apparently found itself back on Uceprotectl3. Does anyone know if Microsoft considers that particular blacklist when deciding to blocklist an IP? Naturally, I've submitted a deliverability support ticket, and will probably have to wait several hours for the result.

Uceprotectl3 and Uceprotectl2 are not respected blacklists. Many people view them as extortion. Microsoft does not use them (pretty much no one does). I have a server that's on Uceprotectl3 and periodically is on Uceprotectl2 and Microsoft is not blocking it.

As always, I'm not doing anything wrong (that I know of at least). Even if someone had hacked my server, my hypothesis is that they'd have to be a very careful and methodical hacker if their aim were to get me blocklisted by Microsoft and only Microsoft. If my server were spewing out spam, I ought to be hitting Spamhaus/SORBS/etc. spam traps left and right. Trust me, one time I was hacked, my server was sending out spam and I didn't know it, and I quickly found myself on Spamhaus XBL.

Any thoughts?

Dealing with Microsoft blocks is always a pain. It requires patience and persistence, but if you persevere, they will eventually unblock you.

I am also on Linode and also a repeat-victim of Microsoft: sjdm.org (and Linode thinks we are jbaron.org, both addresses sort of work).

I strongly believe that nobody pays attention to UCEPROTECT3. I don't think we have ever been off of it, and lately we have 100% success except for a few "user not found" or "over quota" messages, including with Microsoft. The last problem with Microsoft took over a week to resolve despite repeated emails from what seemed to be a person saying that they had brought in their escalation team, or something like that.

That weeklong outage was due to an error message about IPv4 addresses in "our range". UCEPROTECT3, as I recall, looks at IPv6. Microsoft uses only ipv4. Of course we control exactly one ipv4 address. (We do have one /64 ipv6 address, installed at my request by Linode, and that fixed some of the other blocklists that look at ipv6, even though we have another ipv6 address without that range specifier, which is what I think it is.)

Spamhaus is a much bigger problem. I think the /64 helped with that. For the last few months they have not given us trouble.

Please feel free to communicate with me directly at baron@sjdm.org or the address I am writing from. I've spent a lot of time getting things to work, and, at this moment, they do.

Any thoughts?

Thanks,
