[SOLVED] Incoming Email

[alex70]

Hello to everyone!

I have recently installed ZCS on a Linux Fedora 11.
I have changed the MX record at my ISP (the one that is currently mantain my domain) to point to my server.

I can send internal and external emails but I can receive the internal ones only.

All the emails sent from outside to Zimbra receive back the following message:

- These recipients of your message have been processed by the mail server:
admin@company.com; Failed; 5.1.1 (bad destination mailbox address)

Remote MTA mx-vip-it.eu.tiscali.it: SMTP diagnostic: 550 RCPT TO: Relaying not allowed - please use SMTP AUTH

Reporting-MTA: dns; smtp-it-1.weh.tiscali.com
Received-from-MTA: dns; popimap-it-1.weh.tiscali.com (10.39.115.208)
Arrival-Date: Tue, 23 Mar 2010 19:33:17 +0100

Final-Recipient: rfc822; admin@company.com
Action: Failed
Status: 5.1.1 (bad destination mailbox address)
Remote-MTA: dns; mx-vip-it.eu.tiscali.it
Diagnostic-Code: smtp; 550 RCPT TO: Relaying not allowed - please use SMTP AUTH

Can you please give me any suggest to resolve this drawback urgently becouse at the moment I am not receiving any emails.

Thanks indeed

Alex

Is your Zimbra server behind a firewall, and if so what configuration changes have you made to allow SMTP traffic?

[alex70]

Thank you for your reply.
Yes ZCS is behind a router/firewall. It has an internal ip address. Router and firewall have open port 25 redirecting traffic to internal server (ZCS)
The server has also been configured with a DNS with MX to resolving the internal address of the server (es. MX mail.company.com point to 192.168.0.99)

Thank you.

So for the MX change that you made with your ISP which server are you pointing to? It has to be a valid Internet name / IP address for your domain -- probably pointing toward your firewall/Internet gateway.

Outgoing SMTP Authentication - Zimbra :: Wiki

Remote MTA mx-vip-it.eu.tiscali.it: SMTP diagnostic: 550 RCPT TO: Relaying not allowed - please use SMTP AUTH

That appears to be a remote sending issue.

Hello Soxfan and Uxbod,

both of you are right! I have investigated through my ISP and infect they had missed to do the proper setting in changing the related DNS. The last night DNS have been correctly propagated and this morning everything is working like a charm.

Thanks to both of you for your prompt support.

Best Regards,

Alex
