Hi all

I have a server Domino (9.0) with SMTP enabled

The server is behind a firewall with nat forwardingon port 25

On server is installed a antispam software from my customer (ESET)

when I going to check the email (info@domain.it) I have follow response

I don’t understand where is the problem (my suspect is on antispam…)

any ideas?

thx

You can check your antispam software if it is blocking that domain.

If the antispam is blocking that domain , then ask the software provider to unblock that domain.

If the antispam is not blocking that domain , please answer the following questions.

Subject: You also may want to install 9.0.0.0 IF6 in case they are blocking SSLv3

In this link http://www-01.ibm.com/support/docview.wss?uid=swg21653364 you will see 9.0 IF6 posted that had a fix for POODLE attack with implementation of TLS 1.0. Some vendors are disabling SSLv3 and requiring TLS 1.0
