[Mediawiki-l] SMTP -> ERROR

[KAMOHELO MOFOKENG]

Hi All,
 
What does the error below mean:
 
SMTP -> ERROR: Failed to connect to server: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond. (10060) 
SMTP Error: Could not connect to SMTP host. 
 
I googled with no luck, any help is appreciated.
 
Regards,
Kamo
