Text Substitution with pcre:

[Jerrale G]

We want the headers to correct show the mail system, with a bug in 
centos, it shows localhost  or 127.0.0.1 where it should show 
mail.sheltoncomputers.com for PROPER, correct tracking.

/etc/postfix/header_checks.pcre:
    s/(127\.0\.0\.1|localhost)/gi
        REPLACE  mail.sheltoncomputers.com

What is wrong with the above? It is not replacing all instances of 
127.0.0.1 OR localhost with mail.sheltoncomputers.com. You can see where 
we want these replaced in our headers.
