exchange timeout waiting for client input
Posted on 2014-01-24
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:
