Hi,

I have been running XEAMS as SPAM Firewall in front of my Exchange 2010 server in my home lab for a while now. But a couple a days ago i noticed that e-mails are not coming thru so i started to troubleshoot the issue and i cant seem to the issue or fix it.

When i run a diagnostic check - Inbound the result is: Server Communication - Failed.

Like the description says i made sure that the:

- IP/Host is correct; checked even did a nslookup on the machines where xeams is installed on returning the correct IP and Hostname

- Ping the server; checked did this on the machine where xeams is installed on

- is listening on the correct port; Recieve connector on exchange is 25 and in XEAMS configured on 25

What i did test too:

- Enable SMTP Proxy; On

- Asynchronous Processing; On

- Exchange Receive connector -> Permission Groups -> Anonymous users; this is checked

- Windows Firewall; allows TCP-in on port 25

- Machine where XEAMS is installed on; Telnet {IP} 25 -> EHLO; Did get a response from the exchange server

- Exchange Services; all running; even did a restart of all service and a reboot

- XEAMS Host; Reboot server

Specs:

- Xeams Community Edition Version 6.1, build 5960; Ubuntu 17.04

- Exchange Server 2010 Version 14.03.0352.000; Windows server 2008 R2
