Hello,
I am writing due to the fact that I cannot send e-mail from my Exchange 2010 Server to my Yahoo! address for testing. When trying to do so, I get the following error message:
mta1106.mail.gq1.yahoo.com gave this error:
Mail from xxx.xxx.xxx.xxx not allowed - 5.7.1 [BL21] Connections not accepted from IP addresses on Spamhaus PBL; seehttp://postmaster.yahoo.com/errors/550-bl21.html [550]
As one can see, because my IP address is residential, I cannot send e-mail to all addresses on the web. I really would like to use this as my primary contact, and thought of using a proxy. Can someone recommend a good proxy, or workaround for this? I am sorry for posting in Exchange 2013, but I couldn't find the 2010 forum. Thank you to all who reply.
Mike
