can't mail outside of my network

[interactive1984]

Hi,

I am new to setting up mail on my server (snow leopard 10.6)

I have configured the mailserver by clicking on "configure mail service..."

domain name: xxx.nl
Host name: mail.xxx.nl

SMTP IMAP en POP are enabled and running

Relay's
127.0.0.1/8
86.87.38.xxx (ip adres off my incoming internet)
mail.xxx.nl
192.168.x.xxx/24

I told the router to accept incomming traffic from POP and IMAP
I also told my server to accept incoming traffic on these ports (25 and 110)

I have my DNS arranged by the company where the hosting is.

Name Value
@ A 86.87.38.xxx

mail A 86.87.38.xxx

@ MX 10 mail.xxx.nl.

* CNAME @


ftp CNAME @

www CNAME @

I have created zones in the DNS on the server but I am not sure if I had to do this.

I have created in server preferences persons and added them to a workgroup.
this person had his own email address.

I can mail in my network. But that's about all there is

Can somebody please help me out
Take me through some steps which I have forgotten.
I don't know what to do

ThnQ in advance

Do you have a reverse DNS entry for your IP address that points to at least xxx.nl? Otherwise most mail servers will deny mails from your server.

Another thought is to see if your ISP supplies a mail relay for its customers. If so, forward all mail through it.

You can't e-mail people that are outside of your network?
such as somebody@hotmail.com
or
you can't access your mail from outside your network?
