BTW, for info
Windows Error 0x0000274C - 10060 - WSAETIMEDOUT
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.
Possibly firewall issues (maybe suppressing 'unauthorised' attempts to send emails in case they are spam; or, just misconfiguration). But it could simply be that the server is not listening on 25, yes
