Transport only works with .com domain not working with .com.ar domain --eFa-3.0.1.9

[Dawara]

Hi All,
Im adding two domains in Mail transport Settings
1) egxx.com.ar 192.168.x.251
2) esdxx.com 192.168.x.251

only esdxx.com mails pass through
Mails with egxx.com.ar are not working. ( of course DNSs MX's are ok )

When I redirect traffic on the firewall directly to the mail server , both domains are working fine.

Any workaround ?

I've installed eFa-3.0.1.9-VMware

Thanks in advance

What do you see in /var/log/maillog from the domain that is not working?

[Dawara]

I tested with an smtp telnet session and I get
Recipient address rejected: Domain not found
trying to send to the .com.ar domain

[Dawara]

in var/log/maillog file there is a bounch of lines with NOQUEUE : Reject RCPT from .......

Can you resolve that domain on the efa from the console?

[Dawara]

Thank you very much for that reply.

I solve the DNS resolution for that domain from the EFA machine and it is working now ( both domains ) .

So:
If you have 2 or more domains in Transport Settings and one of the is not working, check the DNS resolution for that domain.
