+JH/13 Do pipelining under TLS, with GnuTLS. Previously, although safe, no
+ advantage was taken. Now take care to pack both (client) MAIL,RCPT,DATA,
+ and (server) responses to those, into a single TLS record each way (this
+ usually means a single packet). As a side issue, we can now detect
+ over-eager senders in non-pipelined mode.
