I have client that email is ######@example.com
I tried to send email, but it does not work
I ran dig
against example.com
example.com. IN MX
;; ANSWER SECTION:
example.com. 14399 IN MX 0 example.com.
and found a valid MX record for it.
However I scanned example.com, but port 25 was not open
How can I send mail to example.com in that case?
@ivanivan: Other protocols can use DNS SRV records, which do send a port number, although it's true that MX records used by email don't. – user1686 – 2019-08-01T16:28:49.373
