    I have centos 6 with postfix and few virtual domains on it . Recently I found out that sometimes messages comes from gmail to one of my virtual domains are returned with 550 Relay not allowed and there are no any logs in maillog. Other domains are OK.
    Could anybody give me idea how to investigate this ??

    Check the dns records of these domains of consistency, e.g. at intodns.
