Hello Poly fans, I sent a couple of emails to our yahoo group korgpolyex over the last couple of months and some of them bounced back with a 554 message. Their explanation is here: https://help.yahoo.com/kb/postmaster/SLN5067 .html Except that there was nothing in my emails that ought to trigger any filter. I was wondering if any of you might have experienced the same problem. Because I am pretty much fed up to here with the Yahoo groups service. Cheers to all, /Mike##SELECTION_END##
