If you've subscribed to some RSS feeds, then these are handled by the mail
side of Opera, but at the last count this only accounted for about 140KB
of code so just ignore it and only use the RSS folders on the mail panel
instead. You can right click on the mail icon in the panel selector and
remove it, but that will make navigating your RSS feeds harder.
If you don't have any RSS feeds then the only reason Opera's mail client
will be visible is because you've set it up! It's hidden by default.
