and where is in the centos wiki or in the redhat documentation or in the 
sendmail documentation the info to accomplish that? Do you care to give 
me a url to those (un)official sources? In the sendmail doc I can find 
how to use tls and certificates, but so can I in the postfix docs. There 
is no copy paste settings for gmail to accept my email.

I do not use comcast but the above method works perfectly on my 
broadband cable connection in The Netherlands (UPC). In fact, I do not 
even have to authenticate because I am allowed to simply relay from my 
home ip.
