Connection to remote SMTP server timed out

delivery failure message;

Router: Failed to connect to SMTP host PHILMAC.COM.AU because Connection to remote SMTP server timed out:

i presume this is because the server at the other end is too slow in responding (i can telnet to port 25 on this server and it takes over 90 seconds for connection to establish) so a connection cannot be made, there are a couple of other domains that always generate this message as well.

does anyone know what the default time out value is and how to increase it?

Well, you can try to increase the timeout value by this way :

TCPIP_TcpConnectTimeout=0,120

where 120 is a number of seconds.

Add this in the server’s Notes.ini
