Mail on iPhone auto Bcc's

Dear Forum,

i set up a while ago, maybe on my blackberry, a system were my email auto Bccs myself in so as a copy of the sent mail was generated and could then be downloaded to my MBP once i downloaded email to at the end of the day.

Now i have an iPhone and IMAP email i dont need this but i cant find a setting anywhere that tells my mail to keep auto BCCing me. Any ideas where this would or could be?
