Wrong mail recovery

[lordddevil]

I was mailing some items to my friend but i guess i used the wrong name. Is there a way i can check who i sent those items(an addon or something)?

There was a postal addon where when u type a letter shows name of last persons u sent mail But You should have it installed Before . Now all u can do is wait 30 days to get a mail back if that guy is not looking mail or hoping he would reply . what did u mail btw

actually my friend did it. i paid him for primos and now he is telling that he mailed it to the wrong person which i m sure is a lie. so i wanted to check whether he mailed or not. I logged into his account but found nothing but one of his characters was missing which he told he deleted( which adds up more that he is lying).
Is there any way i can check his mail history or something?
