I will say, as a data-point, that dayjob has had one customer that required us to use a CA for our SMTP server that’s on a whitelist-approved by a certain automaker industry consortium. To the point where when they decided they couldn’t communicate with a secure SSL cert (even though SSL was there), they started faxing us their tickets.
I can imagine other industries requriring the same. What’s annoying is that some commercial CA’s are just barely starting to support ACME, and it’s not as reliable/well-documented/transparent as the free stuff. > On Oct 16, 2021, at 12:10 AM, Grant Taylor via mailop <mailop@mailop.org> > wrote: > > On 10/15/21 11:54 PM, Michael via mailop wrote: >> Remember, each lookup against Let's Encrypt shares information, that can be >> resold. > > What is different for a CA that a certificate is purchased from? > > > > -- > Grant. . . . > unix || die > > _______________________________________________ > mailop mailing list > mailop@mailop.org > https://list.mailop.org/listinfo/mailop _______________________________________________ mailop mailing list mailop@mailop.org https://list.mailop.org/listinfo/mailop
