Try 'telnet mail.2hi.co.uk 587'.

Some ISPs do block port 25 to prevent people sending spam from their broadband connection.

See post 8 all ports blocked on FTTP connection.

$ telnet mail.2hi.co.uk 587
Trying 31.220.111.196...
telnet: connect to address 31.220.111.196: Connection timed out
telnet: Unable to connect to remote host: Connection timed out

So your FTTP ISP is blocking some IP's

QED

I have sent them an inquiry about this.

Not sure if I will get any reply as all my tickets to them since they were taken over by Telecom Acquisitions have never been replied.  >:(
I will phone them on Saturday.

If they where blocking it would it not show up on the taceroute ? as it would stop at my isp's IP address ??
