[SOLVED] Send Zimbra to Relay

[space007]

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
save

restart zimbra

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 ?

Welcome to the forums

Did you also disable DNS look ups on the page where your specified the ISP relay ?

[space007]

yes i did.

From the error message it looks like the ISP server is denying you relay access. Does your ISP require any setup on their end to allow your server access?

Most ISPs will use a alternative port to 25 for client relay.

Nope, this one is for sure port 25

Again nope. At the moment I am having Desknow running on another box with the same configuration (pop3 for in, smtp relay for outgoing mail) on a CentOS box and is working. I am in the process to get off the desknow wagon, zimbra looks like a nice alternative.

Well for whatever reason their server is denying your Zimbra server from relaying messages. Are you sure you don't need to authenticate?

I swear on my root password that is a mail relay for the IPs of that ISP

Hi to all, first thanks for so fast replays and suggestion you all made.

I give up on the relay server, as its everything like is written in wikies and still doesn't work.

I went up the Outgoing SMTP Authentication road.

Made the:

zmprov ms zimbra.server.com zimbraMtaRelayHost mail.server.com:25
echo mail.server.com user.name@server.com:123password456 > /opt/zimbra/conf/relay_password
postmap hash:/opt/zimbra/conf/relay_password
postmap -q mail.server.com /opt/zimbra/conf/relay_password
postconf -e smtp_sasl_password_maps=hash:/opt/zimbra/conf/relay_password
postconf -e smtp_sasl_auth_enable=yes
postconf -e smtp_cname_overrides_servername=no
postfix reload

then because of the error ((Authentication failed: cannot SASL authenticate to server ...: no mechanism available)) I run the following:

postconf -e smtp_sasl_security_options=noanonymous
postfix reload

Now in the Zimbra log got this error:

Mar 18 10:58:24 zimbra postfix/smtp[4642]: D9D406486E: to=, relay=mail.server.com[X.X.X.X]:25, delay=1.2, delays=0.06/0.12/1/0, dsn=4.0.0, status=deferred (SASL authentication failed; server mail.server.com[X.X.X.X] said: 535 Incorrect authentication data)

Naturally, before posting here I tested with Thunderbird pop3 and smtp for the mail.server.com

Ideas ?

I would ask your ISP what they are seeing from their side.
