The understanding I have is that you have to establish trusts with
people.  All the keyserver does is shows that someone using your
e-mail address signed the message.  The individual who receives the
e-mail has to establish trust for the key.  They do that either by
contacting you via another method for confirmation, or meeting you at
a 'keysigning' where you establish a face to face with other people.

I'm relatively new to all of this myself, but I'm pretty sure I read
that in the website.  That would be your best source of
information, short of other more experienced people replying here.
