Firewall drops SMTP Connections from its own WAN interface.

Hi Ulrich,

Could you provide us the dumps for this issue as per the steps mentioned below? 

Step 1: Which port are you using, as per the logs the Port is 25. Is there a dual profile in your Outlook? 

Step 2: Take the dump of the traffic from that system address i.e. 192.168.178.2 and the port used for the connection in console access. 

Command :console> tcpdump 'host 192.168.178.2 and port 25

Output: 

Command :console> drop 'host 192.168.178.2  

Output:

Ulrich,

check that the SMTP relay is enabled on WAN zone under Administration > Device Access.

Regards

The SMTP relay is activated in the WAN Zone.

192.168.178.2 is the WAN Port of the firewall itself.

The firewall wan't to make a connection to port 25.

Ulrich,

what about port 465, port 24?

Check them using telnet.

I have an relay for a specific ip address. And these emails are in the queue.

This is my awarrenmta.log

There are many transactions from 127.0.0.1.

In my firewall log i found the ip-addresses

Why do the firewall uses 127.0.0.1?
