[SOLVED] Internal Ip address Showing in Mail headers

[emmaylots]

I want to customize ZCS to display the external IP instead of the Internal IP 192.168.5.19. ZCS sit behind a firewall and the internal IP is NATTED to an external one. I have tried the Solution in the POST: Outgoing header address Masquerading, but it didn't work.

I am using ZCS 5.0.7 is there any other way to do this using zmlocalconfig.
Some mailservers are rejecting our going mails?

Here is a sample of the header:


Recieved: from xbox.mydomain.com ([192.168.5.19]) by mydomain.com with Microsoft SMTPSVC(6.0.3790.3959); Fri, 10 Jul 2009 08:55:19 +0100

Did you try [SOLVED] Outgoing Header Address Masquerading and if so why did it not work ? Can you post what you used in the regex.

Yes I did, I actually got this from the link.

/^Received: from .+\..+\.domain\.com .+(by zimbra\.domain\.com .+) / REPLACE Received: $1

[uxbod]

So you made the change to /opt/zimbra/conf/postfix_header_checks.in and restarted ZCS ? Does the line appear in postfix_header_checks now ? Can you post the full line please ? Have you checked /var/log/zimbra.log to see what is happening when a email is processed ?

[emmaylots]

zimbra@xbox:~/conf$ cat postfix_header_checks.in
%%uncomment VAR:zimbraMtaBlockedExtension%%/filename=\"?(.*)\.(%%list VAR:zimbraMtaBlockedExtension |%%)\"?$/
%%uncomment VAR:zimbraMtaBlockedExtension%% REJECT For security reasons we reject attachments of this type
%%uncomment VAR:zimbraMtaBlockedExtension%%/^\s*Content-(Disposition|Type).*name\s*=\s*"?(.+\.(%%list VAR:zimbraMt
aBlockedExtension |%%))"?\s*$/
%%uncomment VAR:zimbraMtaBlockedExtension%% REJECT Attachment type not allowed. File "$2" has the unacceptable
extension "$3"
/^Received: from .+\..+\.domain\.com .+(by zimbra\.domain\.com .+) / REPLACE Received: $1
zimbra@xbox:~/conf$

Have you updated the regex to use your specific details ? I believe the original OP obfuscated their own domain name.

Can you please make it a bit simple? Do you mean I should replace all instances of " domain" by my real domain name? Please expansiate?

[uxbod]

Yes, it would be something like

/^Received: from .+\..+\.mydomain\.com .+(by xbox\.mydomain\.com .+) / REPLACE Received: $1

Why do you really need to go to this trouble anyway ?

I am currently using an exchange server as the outgoing smtp relay, i want a scenario where i can use ZCS without an additional smtp relay or server.

Well if you want to do that then just ensure you have a valid reverse DNS entry for your ZCS server. As long as the FQDN of your server is resolvable externally, with a valid rDNS entry, and the MX record for your domain points correctly to your server then you should have no issues. Are you on a static IP aswell ?
