Suppose an e-mail address foo@gmail.com
, everyone knows it is served by gmail.com
site and mail client parameters can be found somewhere near that site.
Now suppose you have an addressfoo@obscuremail.nou
. Can any information be obtained with just that? I.e. can mail web interface be located or can smpt-, imap- server addresses be determined?
You can find the incoming mail server by viewing the MX record for the domain. Web interface, smtp, and even IMAP server could be anything. (IMAP often is the same as the MX record tho). – Tyson – 2018-04-03T13:31:25.260
Right, domain is
obscuremail.nou
in the above? – Dimitry – 2018-04-04T14:59:41.483
