From the sendmail man page:

"      With  no  flags, sendmail reads its standard input up to an end-of-file
       or a line consisting only of a single dot and sends a copy of the mes-
       sage  found  there  to  all of the addresses listed.  It determines the
       network(s) to use based on the syntax and contents of the addresses." 

and

" -i  Ignore dots alone on lines by themselves in  incoming messages.
      This should be set if you are reading data from a file."

RFC-822: read http://www.faqs.org/rfcs/rfc821.html and search for
"period", and see section 4.5.2: Transparency.

This stuff originates from SMTP, but should never get as far as a mail
client. Yet, apparently OE and TB have been "robustified" against any of
this getting through...
