Zimbra Relay Problem - All hosts can send e-mail through my zimbra

[ishak]

Hi all, sorry for my english,

I configured zimbraMtaMynetworks as 10.0.0.1/24, my domain name is example.com but I can send mail with all domain names if my ip address is 10.0.0.1/24. How can I configure zimbra for relay domains? (I have multiple domains).

Thanks.

We don't especially mind that your English is weak, but in this case, it's getting in the way of your meaning. Can you explain your problem in a different way?

What you have done is allow ALL email traffic on the 10.0.0.0/24 network to be treated as LOCAL.
Do you have a firewall between the 10.* network and the world?
My guess would be that your zimbra server is seeing all addressed that come through the Firewall as 10.* network addresses "The Firewall's address".

Put exact address for machines that you want to relay for in MyNetworks.

as zimbra user

zmprov modifyserver YourZimbraServer zimbraMtaMyNetworks '127.0.0.0/8 10.0.0.nn/32

repeat the 10.0.0.nn/32 for each server you need to relay for.

hi guys,
OP sorry for hijacking your thread, though ive got a similar/related question

lets say, i do not want to allow a certain subnet (ie 192.168.0.0/24) instead a select IP from the subnet.. is it possible to create a lookup table/file instead or should i just put it this way:
zmprov modifyserver YourZimbraServer zimbraMtaMyNetworks '127.0.0.0/8 192.168.0.10/32 192.168.0.11/32 up to 192.168.0.101/32'
if lookup from a file/table is possible, i have no idead its syntax
TIA!

Hi again,

My problem is not MyNetworks, I am in trusted network and using outlook, my pop3 server is mail.example.com and smtp server is mail.example.com my e mail address ishak@example.com, when I change my e mail address as ishak@ishak.com I can send e mail with ishak.com but my zimbra have not ishak.com. My zimbra must send only with example.com.
