how to delete space before emails - line by line

[erapop]

I have a big list like:

(space)email1
(space)email2
(space)email3
(space)email4

before each email i have a single space- but i need the email list clean - without spaces, like

email1
email2
email3

(i cant use simple email extract command or program because i have duplicates in list -and i need this emails too) and i need it to be in that line now are

thanks for any help

Sounds like you could use the whitespace catchers in sed, very similar to the last command Luuk posted.
