Sending email - error message

This issue has been solved. See solution.

Hi,

First, excuse me for my wrong English... So, I have a test appliance since last friday, and it works fine, but there is a permanent error:

- The appliance can't send email at all. When I try to send a test email, I get an error message: The email test was unsuccessful: Called Reset() without being connected

I tried the setting with our Exchange 2003 server, and an external (for example: gmail) SMTP server with the same results. Tha appliance can go out to the net without any firewall restrictions.  Has anybody idea how can I resolve this problem?

Thank you in advance!

Regards,

Oh, excuse me.. so, this is the situation:

- WG sits on a VLAN, Exchange sits another VLAN. Between WG and Exchange there is a Cisco router, and there isn't any blocking rules in the Cisco. When I tried to set  up an external SMTP server as a mail server, and I added full access to WG to reach external network, the error message was the same. First, I thought that the Cisco between the GW and Exchange blocks some protocolls, but when I tried an external mail server (and it didn't work too), I run out of ideas...

telnet to your SMTP port from external ,
Means IP address and port 25 what it says and also tracert from your internal client wether you are able to reach . and what about DNS ,MX records.

I think, it has to be work, because all external/internal mail arrived well (by the way, we use a Symantec Mail Security appliance to receive external mail, and it forwards mail to Exchange), and I think MX and DNS work well too (internal domain name resolving works well)...

Then only issue with sending mail from internal to external domains, then check your Forward lookup zones wher you have configured in DNS server or in the client what is nslookup says

From the Administration -> Configuration -> Maintenance page, have you tried using the Test Ping functionality and can you ping the SMTP server you are trying to use?

Will the Gateway from the VLAN the Web Gateway is on to the VLAN where the SMTP server be the IP configured as the default gateway on the SWG?

Cheers,

Kevin

Hi Kevin,

Thank for your comment, but it was a routing problem in our VLAN.
