Dovecot send emails as local and not delivery to gmail

[franmm25]

All works nice 5 days ago and now i can receive emails inside inbox of my account in google apps , i have domain in Sentora , and configurate all MX DNS for google apps , and all works perfectly in more of 1 year ago , but now i see don´t receive emails in gmail for that domain

I tested all in Sentora and in Centos , see the hosts file , also verificate configuration of postfix and dovecot and the last i try add email to server for know if receive emails and right in local mode receive all emails , but for example , the problem it´s only for that domain , and if i try send email from other provider to email in gmail dont receive in local of server but yes inside google apps

By other side if i have form and send email never receive in google apps but yes in local

I try also other time delete all emails about this domain and use this as in the first moment and result it´s the same

I see the logs and see that :

Sep 30 11:15:30 cpadmin postfix/pipe[12152]: 14DF22D8E: to=<mike@mydomain.com>, relay=dovecot, delay=0.15, delays=0.02/0.04/0/0.1, dsn=2.0.0, status=sent (delivered via dovecot service)

But 5 days ago i see in logs and all works perfect an logs show this :

Aug 29 23:55:04 cpadmin postfix/pipe[16430]: 0084622D4: to=<mike@mydomain.com>, relay=dovecot, delay=59145, delays=59145/0.02/0/0.07, dsn=4.1.1, status=SOFTBOUNCE (user unknown)

And in this last case the emails receive perfectly in inbox of my domain´s account in google aps


I don´t know why happend this ,some idea ? Thank´s !!!
