Does your server support port 465? That should be configured to always use SSL without the need for STARTTLS. Perhaps outlook is simply not sending STARTTLS (which makes sense, as Outlook took over the 465 port ages ago). I don't use android, so I'm just guessing here, but enabling port 465 is simple enough and there is no reason not to do it. -- Turning and turning in the widening gyre The falcon cannot hear the falconer;
