Are you getting this from the "confirm friends" email? If so, did you happen to edit the email template from phpMyAdmin? If so, that would be the only reason that you could ever get a "?phpMyAdmin" string attached to an email. Whenever you edit templates in phpMyAdmin, certain tags have to be escaped (such as URL links) because they can interfere with how SQL is executed. In some rare cases, phpMyAdmin can escape the link and append a session key to the URL that was escaped. This issue was corrected with updated versions of phpMyAdmin. If you are using your control panel to access phpMyAdmin, I would look into updating your control panel. If you are using a standalone version of phpMyAdmin (one that you uploaded yourself), I would upgrade it.
