Yes, I have access to another computer to try things out on. Also, what would you not sign up for a free email account with Yahoo?
What do you have against them?
Nope, I don't have anything against Yahoo. I actually use a "My Yahoo" page as my home page, so I do have a Yahoo account. I do not, however, want a Yahoo email account. I have more than enough fun keeping up with the email accounts I already have. In addition, I HATE using a browser to get my mail...and since Yahoo Mail ONLY allows browser access unless you sign up for "Plus" account (and pay money), I have zero interest in a Yahoo account.
So, end result is that I am not gonna sign up for Yahoo email account that I will never use just to help you out. Nothing against you.
I am sure that there is someone else on the forums who does use Yahoo Mail would might be able to test things out, but it shall not be me. Sorry.
BTW, have you tried contacting Yahoo to see if they can help:http://help.yahoo.com/l/us/yahoo/mail/postmaster/forms_index.html
In addition, I am guessing you likely already saw this page, but on the odd chance that you did not, you might see if this helps at all:http://help.yahoo.com/kb/index?page=content&id=SLN4874&actp=search&viewlocale=en_US&searchid=1372294310939&locale=en_US&y=PROD_MAIL_ML
