FIX IT PLEASE

The concept is GREAT there is however a serious issue.
There are commas which are in the senderss return address field that can not be removed. I emailed the app developer and he said he didnt own the app? Please remove the commas.
The concept is better than anything on Pages but in present for is of NO use. Again if you download..there are commas in the return address field that can not be removed....please fix
