[ale] How to undo a mail setting.

[Jim Lynch]

A while back on one of my servers I made a change to something (I can't 
remember what) that causes all mail to my server not addressed to a 
specific user to go to one user.  The effect is that I'm getting a lot 
of bounced spam.  I'd like to reverse that setting.  I did it for 
debugging purposes.  I'm running postfix/dovecot on Centos 6.

I looked through all the config files I can think of but nothing jumped 
out at me.  Can anyone help?

Thanks,
Jim.
