if I dns query my domain I can clearly see that TXT records has benn propagated...
gmail continues to put my "sales" and "support" emails in the spam folder...
I will wait 24 hours, hope that time and better dns propagation will be the solution.

Gmail puts certain emails in the Spam folder regardless of what you do. Are you sending blank "test" emails? Those almost always get sent to spam. If so, try sending a message with actual content (not fake text; remember, Gmail scans mail and it will know if the message is gibberish).

I'm not sending gibberish message.
the message contains normal text as a normal email.

Is it possible for the user to send you a screenshot of what they see in their gmail account for your message, or to reproduce it yourself with a dummy gmail account? When I look at my spam folder messages, they have a message at the top that says something like "Why is this message in Spam? We've found that lots of messages from infinfolkin.info are spam." and has a link for more information on the different classifications. You can also select "Show original" and read the headers Gmail adds for some hints sometimes on what is going wrong.

thanks for the answer gary.
I have done what you have saied.

There is no reason on why they marked the mail as spam but in the "show original" I can see this:

Received-SPF: neutral (google.com: IPREMOVEDBYMETOPOSTONLINODE is neither permitted nor denied by best guess record for domain of apache@mail.MYDOMAIN.org) client-ip=IPREMOVEDBYMETOPOSTONLINODE ;
Authentication-Results: mx.google.com;
       spf=neutral (google.com: IPREMOVEDBYMETOPOSTONLINODE  is neither permitted nor denied by best guess record for domain of apache@mail.MYDOMAIN.org) smtp.mail=apache@mail.MYDOMAIN.org

X-PHP-Originating-Script: 501:proz.php

linode support saied that I don't have any reference of my IPV6 in the dns manager and this may be the cause since the mail is sent using IPV6.
What do you think about this?

I added the IPV6 in the AAAA records and I put
mail.mydomain.org in the reverse dns.
Before of this thread my reverse dns was mydomain.org

ok, all this steps made my SPF PASS!
Received-SPF: pass (google.com: best guess record for domain of

spf passed and mail are not marked as spam from gmail.
good.

I bump this old thread for a question.

Why the reverse DNS should be mail.mydomain.org instead of mydomain.org ???
What is the reason of this? Why google want this?

I don't believe it should be mail.mydomain.org - iirc, the best thing is to have the reverse DNS set to what you mail from. So if you mail from foo@bar.com set your rDNS to bar.com. Some mailservers check the RDNS records to prevent spam.

I try to set it to bar.com and see what google does.

There is no reason whatsoever why the rDNS needs to match the domain of the email. Lots of email on the internet is sent by third-party servers that do not match the name of the sending domain. The only things that might be checked on the rDNS would be that it matches forward DNS, matches the HELO name of your SMTP server, and that it doesn't contain obvious terms like "dialup".
