I want postfix to send out all email via noreply@mydomain.com

My main.cf looks like

sender_canonical_maps = regexp:/etc/postfix/canonical
local_header_rewrite_clients = static:all

and my canonical file looks like

/domain.local/ noreply@mydomain.com

Anybody know why this isn't working? I have already tried restarting the server.

I am not sure what the /domain.local/ part does, as the content was motivated by a blog post.

Are you sure all your outgoing emails look like user@domain.local? Check /var/log/mail or /var/log/maillog file. –  Laurentiu Roescu Nov 20 '12 at 7:07
    
@LaurentiuRoescu I don't know what /domain.local/ means. A lot of my outgoing emails looks like uname321@yahoo.com . Basically I need to change the FROM field to be noreply@mydomain.com –  Mikhail Nov 20 '12 at 20:25

domain.local is the pattern. When pattern matches an email address it is replaced with noreply@domain.com.

If you want everything replaced you can use .* as the pattern.
