exchange timeout waiting for client input

Hi, I have multiple accepted domains on a SBS 2008 server receiving thousands of e mail each month. Recently E Mails sent from companies that use BT as their provider are being bounced back with the following information. I have deleted my receive connector and recreated, checked my logs but all to no avail.

I changed to Fibre Optic broadband around the same time as this started happening, going to try a new router tonight.

Delivery has failed to these recipients or distribution lists:

What kind of firewall do you have in place?  Most likely that is the cause of this problem.

Hi, I have tried another Router and this hasn't helped.

Windows SBS Firewall, did have kaspersky but have disabled that and still the same.

Hi, take that back as I forgot to open port 25 on the router and all ok now. Seems like the Netgear cable router was blocking some ISPs from sending e mails to me server !
