Oh, of course. I'm sorry if I came off brusk. You are using a free
software email server and letting us know about issues you noticed, that
is AWESOME. If you are continuing to test for this issue with other
email servers, I would really like to know if it comes up in your
logs. If it doesn't, perhaps its not as common in exim as I thought and
we really should change something on our end. You advancing the state of
federation and software freedom in email, unlike the big providers with
their black box software that rejects mail and classifies it as spam
without explanation and never reply to any questions. If you publish a
note about this issue somewhere, a mailing list, a wiki, something, it
would be great for the free software community. Thank you!
