MX not found
I have setting up a mailserver using postfix, but I have some problems to pass the antispam barriers (even when I send one message)... I don't know if this can be a MX issue but when I check my DNS with DNSLookup, I get the message "MX not found".
It seems that all is ok in my /var/lib/bind/mydomain.hosts
mail.mydomain. IN A xxx.xxx.xxx.xxx
mydomain. IN MX 5 mail.mydomain.
Where is the problem?
Thank you and sorry for my bad english

The best way to find out whether your MX record is OK or not is to send yourself an email!
What is the domain in question?
Did you set a SPF/TXT record?
All generalizations are false, including this one. Free hosting

When I send me a mail it works, but not with all domain (1&1 don't receive my mails and the others receive them in spam), but I don't know if this is a problem of the postfix configuration, I just want to solve this DNS problem and exclude it from the causes of postfix malfunctions.

but I haven't a TXT one for "mydomaine"
I need to add others records?

Generally that error is DNS related.
Can you run through your steps. Are you sending out and to who. Does anyone receive it. Can you send internally?
