[batradio]

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>
192.168.1.100 192.168.1.110

MX Record is: mail.cseorks.com

You are not telling us how your current setup is not working, but this should give you pointers on the setup you want.

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

[volksman]

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

[batradio]

<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]

[topdog]

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 ?

[batradio]

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
