According to https://www.rfc-editor.org/rfc/rfc5321#section-4.5.2 in case the first char of a line is a period, one additional period has to be inserted at the beginning of the line.
In case the second period is not present the first one is simply omitted which can produce e.g. broken domain names / FQDNs.
