We’re still unable to send any email successfully to Yahoo addresses. After experimenting, it seems that all messages to any Yahoo addresses are being returned with “message not allowed”.
I talked to our ISP about the problem, and they say that this is happening only to us; i.e. it is specific to our email account. This may mean that we have been maliciously reported to Yahoo as spammers.
As a result, we can’t reply to any messages that come to us from Yahoo. At this point there doesn’t seem to be anything we can do about it.
If you have a Yahoo account and are waiting for a reply from us, I apologize. You may want to complain to Yahoo and ask them to unblock unspiek(at)chromatism.net and dymphna(at)chromatism.net.
