Can please anybody help me,
This is my box: Debian Netinstall 5.04, Zimbra (zcs-6.0.5_GA_2213.DEBIAN5.20100131173855)
got a domain name for the familie, zimbra in internal network all of us.
Followed the wiki about splitdns and the Zimbra Collaboration Suite (ZCS) Open Source Edition v5.0 On Debian Etch
MX for domain.com is resolved internally, thats fine.
Hosts file is fine.
For incoming mail I will use external pop3 from my domain.com, as for smtp I will use the ISPs mail relay.
Getting mail via pop3 works..
as of sending emails it doesnt.. internal mail works
- Configuration - Server config i specified ISP mail relay server and port,
- Unchecked Enable authentication
after sending the email got the message back "Undelivered Mail Returned to Sender"
Client host rejected: Access denied (in reply to RCPT TO command).
what can be wrong with the configuration ?
