[Discuss] Yahoo and Exim4 configuraiton

[bill at horne.net (Bill Horne)]

I  have just seen an odd log entry after sending an email to yahoo, 
although I don't know if it's something I need to work on: I just sent 
an email to a yahoo user, and I found the following in my Exim4 log:

2014-05-16 15:05:01 1WlJgz-0002cM-QR <= bill at redacted.invalid U=bill

is not acceptable (not lo

Please tell me if this indicates a configuration problem with my Exim4 
setup: it appears to be yahoo asking for TLS, but I don't see similar 
entries for other ISP's, so I wonder why yahoo is different.
