Postfix - masquerade not working

I know the setup is simple but for some reason its not working on my systems. I can send email to external locations and its sent without a problem but the source address is coming up as [email protected] instead of [email protected].

I am running centos 4 with postfix 2.2.10. I have set up the following in main.cf:

myhostname = host.mydomain.com
mydomain = mydomain.com
myorigin = $myhostname
masquerade_domains = $mydomain

Has anyone else ran into this same problem or does anyone have any suggestions?

TIA!!

 

I also checked the logs and when mail is sent it shows as being sent from [email protected].

Everything else in the logs look ok.

Thanks!

(I can provide the full my.cnf if necessary)

 

You must set the correct email address in your email client.

 

how do you set up the mail client? its that the point of setting up masquerading??

 

This should give you the idea: http://mail.cs.uiuc.edu/relay/outlook-config.html (the last screenshot is not necessary).

 

i am not using a windows client. i am sending mail from the command line on the same linux server that i am running postfix

 

Then you must specify the sender address on the command line. You can read the man page for the command you use.
