I am trying to contact a person which employer organisation states can be reached at <name>@netscape.net. I have sent an email to this address from my gmail account a few hours ago, and so far have not received the standard message one gets if the address does not exist:

The original message was received at Fri, 31 Feb 2017 09:50:59 -0400 (EDT)
from mx0b-00256a01.pphosted.com []

   ----- The following addresses had permanent fatal errors -----
<name>@netscape.net (reason: 550-5.1.1 The email account that you tried to reach does not exist. Please try)


I know nowadays you can set up email accounts of the like name@whatever.example. However, this person is an old academic (80+), now retired, and I get the impression that email might have been valid at a time when netscape was still around.

How can I know if I have the sightest chance of getting a reply? Is there anything I can do to test through a different mean if an email address is still valid?


I got a reply - he answered! Amazing!

    Setting up a custom domain email as per that question is on-topic. We don't accept questions here unless they are related to your site or domain. – Stephen Ostermiller Aug 31 '18 at 18:04

There’s still an MX DNS record for netscape.net, which points to an AOL/Yahoo mail server, so your email should be going somewhere.

  • Thanks! How do you know this? Can you add some links or reference? (not that I don't believe you, but I want to learn about it). – luchonacho Aug 31 '18 at 15:17
