right.  the issue is not whether you accept LF as a command terminator
(unless you use the same routine to read commands as you do to read DATA)
the issue is whether a server accepts LF . LF as a message terminator 
for DATA.  related issues include when a client sees a LF . in a message
body - does it send LF . or LF ..?  and when a server sees LF ..foo in a
message body, does it remove the first dot?

note that detecting the use of bare LF as a command terminator may be
an effective way of identifying broken clients before the DATA phase,
where it's easier to provide meaningful error messages.
