RE: Best TAC Services from Equipment Vendors
That honestly is what my experience used to be but this has not been my observation recently, even when we as a large NSP provide all detail and literally ask about possible bugs.

If something is critical enough, and you push hard enough, Cisco will move heaven and earth to solve your issue.

The "companyname" part is evidently Not reliable. Often the name [dot] onmicrosoft [dot] com is unrelated to Any recognizable business or company name. Companies can generate extra onmicrosoft[dot]com domain names. Possibly an existing tenant for some unrelated company could add nanog[dot]onmicrosoft[dot]com and change it to their default domain, if they wanted. Even if it were; the information could be tampered with on a compromised tenant where the spammers simply change the names after breaching the tenant. Likewise spammers might use robots to Signup for 365 services online, and that there's little verification a requestor's Name and Company name exist beyond the ability to charge whatever stolen payment method was provided by the spammer. Because it behaves like a dynamic domain; with very low friction for scammers to generate new ones quickly. It seems that Refusing all mail from subdomains of that domain by default Other than specific ones you whitelist would be a good policy. > You then add domain aliases if you want to use your own preferred domain name. > Thanks > Travis -- -JH
