Smarthost and "Error 40.4.1: Direct mail from client hosts does not accepted"

[blusowiec]

Hi,

I have problems with this error, from some our clients:

<email@domain.com>: host fast.mironet.ua[193.178.147.152] said:
550-"Error 40.4.1: Direct mail from client hosts does not accepted, use
your 550 ISPs mail server" (in reply to RCPT TO command)

Email header is looking like this:

The answer is in the error message from the server (highlighted in red above).

I'm not sure which one you're saying is your server but neither of them appear to have a valid reverse DNS (for your server):

host 85.128.181.155
155.181.128.85.in-addr.arpa domain name pointer aly155.rev.netart.pl.

host 58.10.125.24
24.125.10.58.in-addr.arpa domain name pointer 58-10-125-24.static.asianet.co.th.

Thanks for your answer.

host 85.128.181.155 -> this is my relayhost - I'm using this server to send my emails.
host 58.10.125.24 -> this is my local (in Thailand) public IP

If you read the Admin Guide or search the wiki for authentication or even go to the Admin UI and set-up a relay to your ISPs mail server that should solve the problem (you could even search the forums for an answer).

As I've said in my previous post, apparently neither of those has valid reverse DNS records (look at the output I've posted). In fact, your DNS records don't even point to your local IP for direct mail delivery to your Zimbra server..

I have like there: Outgoing SMTP Authentication - Zimbra :: Wiki
I was reading about smtp-auth but I cannot find where is the problem...

My main.cf
------------
...
relayhost = ultimatravel.nazwa.pl:587
...
mydestination = localhost
myhostname = zeus.ultimatravel.com
...
smtp_sasl_auth_enable = yes
smtp_sender_dependent_authentication = yes
smtp_sasl_password_maps = hash:/opt/zimbra/postfix/conf/sasl_passwords
smtp_sasl_security_options = noanonymous
smtp_cname_overrides_servername = no
sender_dependent_relayhost_maps = hash:/opt/zimbra/postfix/conf/sender_relay

sasl_passwords:
------------------
daniel@ultimatravel.com daniel@ultimatravel.com:111pass222
...

sender_relay:
---------------
daniel@ultimatravel.com ultimatravel.nazwa.pl:587
...

Zimbra is sending every day lots of emails, but only with two clients i have this problem.
Do you have any idea where is the problem??

Thanks again!

Problem was resolved.

My ISP has problem to resolve my revDNS (unknown [58.10.125.24]):
