Alternate SMTP port number in alias file

[Jim Balo]

Hi,

I need to redirect a few accounts on my Postfix server to a different SMTP 
server, but this server is using port 2525 instead of 25.  I have tried this in 
my /etc/alias file:

"joedoe:   [EMAIL PROTECTED]:2525"
and
"joedoe:   [EMAIL PROTECTED] 2525"

The above does not work.  How can I accomplish this?

Thanks,
JB
