Indicator light flashes for all "sent" emails in blackberry bold 9790

HI, i am having blackberry bold 9790 phone and in that i have always noticed as the indicator light is flashing for every email I take delivery of, but also for every email that I Send..! this is something wired as well as simply annoying because I make use of the light to know whether or not I have to deal with something and I definitely don't require to deal with things I just dealt with. I've looked all over the setting but couldn’t found any option to fix it, or might be I am missing any option, please let me know if any.

Obviously you must be missing something, because as far as i know there should be some settings for getting those indications turned off.

Anyways have you searched them in the manual given to you? I am not sure about that but still you may find any solution from there because they may have mentioned any steps to get them turned off.

there could be something in the potion under the alerts, but still can you please let me know which version of operating system is installed in your phone so that i could assist you better!
