[Bug inetlib/29340] New: SMTP Messages with lines with a leading dot (or period)

[rslemos at gmail dot com]

Trying to send an SMTP message with a CSS attached, and the output at MUA was
messy. The cause was the CSS lines, which (almost all) start with a dot.

According to RFC 2821, section 4.5.2, on Transparency, whenever a dot is found
at the beginning of a line, the MUA should escape it (with another dot); the
server MUST remove THE FIRST leading dot IFF the line is not a dot by itself.

Patch follows (albeit a simple one, not the best one)
