Whatever you have done, it fixed the problem. I had no problem sending
messages to that address using BDAT. No error messages were reported either.

As EIMS works internally with messages internally stored in raw RFC 822
format, all it does is send the length of the message in the BDAT command,
then send the message. It leaves no posibility of the size being wrong. It
was actually a lot easier to implement BDAT than the normal transfer method
as there is no need to pad lines starting with a '.' or search for
<CR><LF>.<CR><LF> at the end.

EIMS 1.x supports sending using BDAT, but not receiving. Future versions
will support receiving as well. I don't know of any other systems that use
it. Let me know if you want to do any compatibility testing in future.

Yes, there are two CRLF pairs at the end where the Xes are.
