SMTP AUTH some day. :-)
If a plugin running the ehlo hook add something to the ARRAY
reference $self->transaction->notes('capabilities') then it will be
added to the EHLO response.
Add command_counter method to the SMTP object. Plugins can use this
to catch (or not) consecutive commands. In particular useful with
the unrecognized_command hook.
