Hi,

Anyone know how to work around this error or how to solve it:

09-14-04 09:00:44:671 -- (5424) Socket Error # 10061 Connection refused. - message queued

It is something with listening on port 25 or 110, but how can I make the server do that. It is Windows Server 2003. If I use the command "netstat -an" I can see what port is listening on, but 25 and 110 is not mentioned.

Thanks for any suggestions.

/ Kim

the netstat command will only show you the connections that are already made on the server. If an application is listening on a socket (port), but no connections are made to that port when you issue the netstat command, it will not be listed.

The "connection refused" usually means that SpamFilter could not connect to the destination smtp server you specified where to forward all the emails. The destination port is usually 25, unless you specified differently within SpamFilter. Please note that port 110 is usually reserved to POP3 traffic, not SMTP.

You can usually verify that your destination SMTP server is working correctly by issuing the following DOS command from the SpamFilter server:

telnet your_destination_smtp_server 25

and see if you get a welcome banner. If you specified a port other than the default 25, please use that instead.

Hi,

I think I know what the problem was. In destination server we wrote 192.168.10.5:25 but it should be a space instead ie. 192.168.10.5 25 (not a :)

Then it works.

Thanks for your help.

Kim,

In the "Destination Server" under the Settings - Configuration tab you should actually only enter the server's name or IP, without any port numbers, in the "Name" field. If you use a port other than the default 25, then you should enter that in the "Port" field.

If instead you are adding customized destination SMTP servers for some or all of your local domains in the "Local Domains" list, then each entry should be in the form:

MyDomain.com:my.smtpserver.com:25
