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
