If you are behind a blocked mail server, you need to be subscribed to
post messages. That is documented in the bounce message AFAIK.

Thanks for the testing, you've shown that there is non thread safe code,
probably in the fhandler_consoler in cygwin, or possibly in the MS
Windows console code. Right now we don't know which.

This will get fixed... eventually :}. If you'd like to help fix it,
we're always happy to help a new developer get started.
