Sending mail through an external ISP

Postby mszych » Fri Apr 06, 2018 10:56 am

I need to change form of sending email with zimbra. Now zimbra server is on public IP address in DMZ, but now i need to change network configuration to send all email trafic via ISP.
I was change server to a private IP and change the MX to set on my ISP.
In global settings in MTA tabs i was set in external MTA delivery my ISP, in server settings i made the same things.
Is that correct settings, should i do something more?
How i can check that all email go only via ISP
I will be grateful with any help

use smarthost

Code: Select all

echo relay.xxxx.com postmaster@xxxx.com:password > /opt/zimbra/conf/relay_password
postmap /opt/zimbra/conf/relay_password
postmap -q relay.xxxx.com /opt/zimbra/conf/relay_password
zmprov ms `zmhostname` zimbraMtaSmtpSaslPasswordMaps lmdb:/opt/zimbra/conf/relay_password
zmprov ms `zmhostname` zimbraMtaSmtpSaslAuthEnable yes
zmprov ms `zmhostname` zimbraMtaSmtpCnameOverridesServername no
zmprov ms `zmhostname` zimbraMtaSmtpTlsSecurityLevel may
zmprov ms `zmhostname` zimbraMtaSmtpSaslSecurityOptions noanonymous
zmprov ms `zmhostname` zimbraMtaRelayHost relay.xxxx.com:587

I set command that You send me, i was only changed relay.xxxx.com to my ISP name and zimbra postmaster password
now when i try to send email i got message host said: 550 Relay access denied (in reply to RCPT TO command)
My ISP is sophos devices, i set there Authenticate Device with Smarthost and set user and password zimbra postmaster
I'm shure that the password is ok
What should i check
Where in zimbra i can check that the smartost was configured properly
