Unblock port 25 for small email server
Hello. I have a home office and I run MS Exchange 2010 for home/business emails. (4 users) I just recently changed my Internet access to AT&T Uverse.
My server is receiving Inbound emails perfectly. OUTBOUND emails are not going out.(stuck in MS Exchange queue) I have been using this server for 16 years with a different ISP. (different versions of Exchange along the way)
Can you remove the block on port 25 so that I can receive emails from outside?
