I think you may have misunderstood the semantics of Michael’s reply. A cursory search of this mailing list’s archive will show you that Linode are like Marmite - loved or hated, in terms of reputation, in equal measure. They have a decent response team but the size of the operation and the automation/APIs/web UI they offer means it is almost trivial to turn up an IP, burn it with outbound spam, get whacked, turn up another one and so on. Since late 2019, Linode has blocked outbound SMTP for ALL customers by default, until a support request has been approved to grant removal of the filters for the requesting customer. Support must follow a procedure to verify certain criteria before granting SMTP access, and such requests are tracked. As of this past week, additional steps are in progress to better handle the vetting, and better catch customers who might be gaming the system. Note, Linode has in excess of a million customers, each with one or more VM (Linode), and corresponding IPs. There are also resellers who use Linode resources to host their customers. In at least one recent incident, abuse was tracked down to a reseller with a single abusive customer burning through IPs with SMTP access, so the reseller has been put on notice and has committed to default blocking, and a higher level of vetting before granting SMTP access. I am a Linode employee, though not in the department that handles this kind of issue. For some recipients’ admins, Linode are “block on sight”. It may be that MS have finally had enough, and as has been mentioned many times - their network, their rules (which also applies to you, and Linode, and everyone on this list). We are talking about a massive amount of IP space, and lots of collateral damage for those who do block large chunks of it. I've been impressed with how receptive the powers that be have been to feedback about recent issues that I've passed along and from the tickets from customers. I am optimistic about the situation, for what it's worth. Mark -- Mark G Thomas , KC3DRE ___ mailop mailing list mailop@mailop.org https://list.mailop.org/listinfo/mailop

Re: [mailop] [EXTERNAL] Microsoft IP Filtering - sort of full details
The bounce message is immediate. The response to the forward is immediate. I have gotten the next step after the forward twice, once it took 4 hours, once it took 6. Both of these are in the past 3 or 4 days. It's now been 12 without that. I don't think you can blame this on a linode IP delaying responses, since the response when I forward is immediate. This is something on the Microsoft side. As said below, I will try again tomorrow with a different from and to address. John On 1/12/22 8:47 PM, Michael Wise via mailop wrote: LiNode IP.
