Yes, it is.  The issue you are seeing is the EXACT issue that the other
discussion talked about.

That other discussion already explained what to do.

I already showed code to get TIdSMTPServer's TStream data into a TIdMessage.
Please go read the other discussion again.

TIdMessage cannot directly parse the TStream data because of the issues
described in the earlier discussion.  If you have NoDecode set to False,
then you will have to preprocess the TStream data to reformat it in a way
that TIdMessage.LoadFromStream() can handle.  Otherwise, set NoDecode to
True instead, and use the code I posted in that discussion (TIdMessage will
not parse the data into the MessageParts collection when NoDecode is True,

As it should be.  TIdSMTPServer does provide the correct data in the
TStream.  TIdMessage simply cannot handle it properly at the moment, since
it was designed to parse data that is formatted in another way.

That is because the TStream data is not formatted in a way that TIdMessage
currently requires.  Hense the current delemna in TIdMessage's core design
that needs to be addressed by Indy's developers.  You will have to manage
the data a little more manually in the meantime.

> Is there a problem in idMessage.LoadFromStream with periods?

Yes.  The other discussion went into great detail about that.

> If there is then how do I get around this?

Again, please read the other discussion more carefully.  I did post code to
work around it.
