I have it back in place, Not sure where to go next...

Here is what I found on the internet for using comcast as relay host...but I still see smtp requests going out to dest port 25..

=======================================================================

The geniuses at Comcast (my ISP; no, I don't have any choice) have
suddenly decided that I am a source of spam and hence require me to
send e-mail to port 587 instead of port 25.

So now I am trying to figure out how to make this work, given my
postfix-based system running on Mdv 2006.

I have made the following changes to my main.cf file:

----

# morons. Send it to port 587
relayhost = [smtp.comcast.net]:587

smtp_sasl_auth_enable = yes
smtp_sasl_password_maps = hash:/etc/postfix/sasl/sasl_passwd
smtp_sasl_security_options =

----

Following the instructions at
http://freelock.com/kb/Postfix_relayhost: (but amending the directory
so that it's /etc/postfix/sasl instead of /etc/postfix):

1. I created a file /etc/postfix/sasl/sasl_passwd which contains
[smtp.comcast.net]:587 my- username:my-password

2. I executed:
postmap /etc/postfix/sasl/sasl_passwd

3. I executed:
postfix reload
