[Elecraft] MSN.COM E-Mail Addresses Blocked ??

[Ken]

Hello all,
 
I've tried to post several messages to the list server numerous times recently. The last time was a few months ago and it worked fine. Both "msn.com" addresses I'm subscribed under no longer work. Using "plain text". 

Sent several requests to Elecraft listserver help and no response.
 
Has msn.com been blocked somehow?
 
I switched to my "verizon.net" address and via a "test" mesage is seems to work.
 
 
Thanks,
 
Ken, W2GIW
