Hi,
I am trying to configure an email server on my linux box using postfix and dovecot. But I am behind a firewall. The email is working fine whithin my lan but no email is going outside the lan i.e. any email I send to yahoo , gmail etc. are not being sent. Similarly, when I send email from yahoo or gmail to any email on my domain, I get back a Mailer Daemon message saying that the account name doesnot exist on the domain.
Can anyone help??
Thanks,
Sivakalyan.
Give us network details and we can help. Right now I know you are behind a firewall, but I don't know anything about your network topology other than that.
Hi,
I have a small lan behind the firewall/router. The topology is like this:
- Router / Firewall
- LAN
-- Linux Box (Centos 4.3, 2.6 Kernel)
--- This is the machine on which I want to setup the email server. It is also the DNS and the DHCP server for our lan.
-- Two Windows boxes
--- These are general clients. They don't run any services.
- Domain Name
-- Internal : example.com
-- External : www.sivakalyan.com
Hope this information will be useful.
Thanks.
First, you seem to be missing an MX record for sivakalyan.com.
I sent a message to root@www.sivakalyan.com, which will attempt to deliver mail directly to 70.225.41.10 and it seemed to work ok.
Mar 30 12:55:09 eudora postfix/smtp[5087]: C7CEB97BD: to=, relay=www.sivakalyan.com[70.225.41.10], delay=1, status=sent (250 Ok: queued as 7A947DAAD3)
Try setting up your MX record and then try sending mail to user@domain.com.
