I am running Fedora 23 server. Among other services, I want to deploy
a mail server with postfix.
1- I registered on my DNS provider a A and MX records:
------------------------------------------------
mail.thetradinghall.com. 86400 IN A 212.147.52.214
thetradinghall.com. 86400 IN MX 10 mail.thetradinghall.com.
-------------------------------------------------
2- tested with dig
-----------------------------------------------------
$ dig mail.thetradinghall.com @ns1.he.net
;; ANSWER SECTION:
mail.thetradinghall.com. 86400 IN A 212.147.52.214
$ dig thetradinghall.com mx @ns1.he.net
;; ANSWER SECTION:
thetradinghall.com. 86400 IN MX 10 mail.thetradinghall.com.
--------------------------------------------------------------
3- installed, configured and started postfix.

-----------------------------------------------------------------------
Nothing set in a first step as for TLS./etc/postfix/master.cf is the
original installed one.
No entry in iptables, as until now, I let it permissive :
# iptables -L
----------------------------------------------------------
Chain INPUT (policy ACCEPT)
target prot opt source destination
f2b-pam-generic tcp -- anywhere anywhere
Chain FORWARD (policy DROP)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
Chain f2b-pam-generic (1 references)
target prot opt source destination
RETURN all -- anywhere anywhere
-------------------------------------------------------
Now when testing with telent, I don't have the answer expected :
220 mail.thetradinghall.com ESMTP Postfix
$ telnet mail.thetradinghall.com 25
Trying 212.147.52.214...
Connected to mail.thetradinghall.com.
Escape character is '^]'.
-------------------------------------------------
I must have misconfigured something, but I have no idea what. After
lots of reading, it seems to me the setup is correct.
Thank you for any hint.
