There seems to be a bug in gmail that can suddenly start occurring on some accounts. Whenever you send an email that sent message immediately appears in your inbox as well as in your sent items (as if you cced yourself in on the message).

This quickly becomes very annoying and although some people have had success at stopping it by turning POP off and on again, nothing seemed to work for me.

The solution I eventually settled on was to create a filter to remove this stuff. The filter looks like this:

from:([email protected] OR [email protected] OR [email protected]) to:(-([email protected] OR [email protected] OR [email protected]))

Do this: Skip Inbox

This will send any email from any of my email addresses straight to archive (alternatively you could delete them entirely if you wish).

However, notice there is an exception to this. It will not skip the inbox if the message has been sent to me. This is because like many people I occasionally send emails to myself.

Hope this helps if you are having the same problem.
