Exchange Port 25
Posted on 2013-05-10
I manage my own emails via Exchange 2010 at my home. I was thinking of switching my internet provider from ATT to Comcast but Comcast blocks port 25 and they will not allow it for residential connections. They are only allowing port 465 and 587, so the question is can I use port 465 for Exchange to send and recieve mail, and will my SSL certificate be affected or will I need to create a new CSR. Comcast has a really good deal but I don't know if I can use exchange with the ports they allow. Please and let me know and give instructions or a link on doing this. Thanks in advance.
