Description
When a messages is posted using the web-forum where the last paragraph happens to be 510 characters long followed by a period, its BODY is returned by the NNTP server followed by *two* ".CRLF" pairs instead of one.

Note that:
- ".CRLF" deontes the end of the body.
- a single line containing just an "." should be 'escaped' and returned as "..CRLF"

The current mishap of the server can cause newsreaders to fail depending on how newsreaders handles this.

For instance when downloading all articles using pipe-lining in XanaNews this will result in "pipeline out of sequence error" two times on the following articles (both can be found in embarcadero.public.delphi.non-technical:
article 5052: https://forums.codegear.com/thread.jspa?messageID=22131&tstart=0#22131
article 45490: https://forums.embarcadero.com/thread.jspa?messageID=207036&tstart=0#207036

Since a normal response (to an article or body command) ends with the ".CRLF", the extra ".CRLF" is sometimes read/used as an answer to the following command given by the newsreader. This can result in errors, like "unexpected reply", "invalid reply" or "Perhaps the article has expired" in (other) news readers.

Both above posts will give time-out erros when using MSOE and Windows Mail.

Steps to Reproduce:
When using MSOE try to donload:
article 1874 in embarcadero.public.test:
  https://forums.embarcadero.com/thread.jspa?messageID=143682&tstart=0#143682
-or-
article 2342 in embarcadero.public.test:

When using Thunderbird, try to download:
article 2305 in embarcadero.public.test:
  https://forums.embarcadero.com/thread.jspa?messageID=245460&tstart=0#245460
(and then any other message).


When using XanaNews (<= v1.19.1.296), try to download:
all Articles of embarcadero.public.delphi.non-technical
(it will result in error "Pipeline out of sequence")
