Hello!

This morning I have got this reply from courier mail server 0.54.2

---------------------------------------------------------------------------

UNDELIVERABLE MAIL Your message to the following recipients cannot be delivered:

<meta@bestguidedes.info>: <<< This domain's DNS violates RFC 1035.

---------------------------------------------------------------------------

Anyway domain exists in DNS

nslookup set type=MX bestguidedes.info

Server: 127.0.0.1 Address: 127.0.0.1#53

Non-authoritative answer: bestguidedes.info mail exchanger = 10 217.20.163.50.

Authoritative answers can be found from: bestguidedes.info nameserver = ns1.fastmessage.org. bestguidedes.info nameserver = ns2.fastmessage.org. ns1.fastmessage.org internet address = 62.149.13.107 ns2.fastmessage.org internet address = 217.20.163.50

Please, why .info DNS violates RFC 1035, what could be the problem ?

Host name and not IP address should be in the MX record. Best option is to contact admin of that domain and ask to respect standards. Quick and temporary option is to add a record to your esmtproutes file: bestguidedes.info: [217.20.163.50]

P.S. Subject in the e-mail messages is for the good reason -- to know what the messages is about without opening it. Please use it. And please, describe well what the message is about.
