Gmail in Apple Mail self message issue..

Hi. I have a gmail account that I access using Apple Mail. Account is IMAP.

I frequently CC or Blind CC myself on outgoing messages.

Most of the time the messages appear in my inbox when I check mail. Sometimes (1 out of 3) they do not appear in the inbox. They do appear in the Gmail>All mail folder and in Gmail on the web.

Any ideas?

Thanks
