    I'm at my wites end with this problem can some one tell me what is wrong with my configuration. I'm trying to install E-mail Gateway (smarthost). The smarthost will do greylisting, spam, & Virus scanning after that is completed to passes it on to the Internal Mail Server

    <Internet> ---> <Mail Gateway> ---> <Internal Mail>

    I have looked at all configuration at postfix web site and still can't get it to work

    what I'm trying to do is

    Mail comes in by internet goes to my mailgate but it doesn't get delivered to my internal mail server

    Can some look at at my configuration and see if I'm doing anything wrong I'm a newbie to postfix

    I might be wrong but I think this has to do with your transports. Not familiar enough with it to provide more detail though...

    Transport

    <Internet Mail> ---> <Gateway Mail> ---> <Internal Mail>

    <Gateway Mail Server>
    mailgate.cseorks.com
    IP: 192.168.1.100

    <Internal Mail Server>
    mailsrv.cseorks.com
    IP: 192.168.1.110

    Mail doesn't get delivered on the internal mail server

    The transport file, located on Gateway Mail Server
    mailsrv.cseorks.com smtp:[192.168.1.110]

    I have not followed your config fully but first thing i can pick up is that you have specified the mydestination option which should be blank. Did you really read up on the link i gave you ?

    It is working : Mail Gateway Problem

    Thanks for everyone help

    I had multi problems and looking at the "mail log"

    1. I use Comcast as my ISP they were block me of sending e-mail and the fix for that is:

    In my MailGateway (smarthost) added a few lines of code in "main.cf"
    relayhost = smtp.comcast.net
    smtp_sasl_auth_enable = yes
    smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
    smtp_sasl_security_options =

    Created a file /etc/postfix/sasl_passwd
    smtp.comcast.net <userid>:<password>

    postmap sasl_passwd


    2. In MailGateway (smarthost) added a few lines of code in "main.cf"

    mydestination =
    local_recipient_maps =
    relay_domains = cseorks.com

    Change the transport file
    cseorks.com smtp:[192.168.1.110]

    re postmap the file
