Hello Daisy,   Thank you for your reply.  I am using an email client (Outlook) so I have tried sending emails via Post Office and this works.  However this is really not a satisfactory solution, certainly not long term, as I have multiple folders set up in Outlook that I wish (need) to utilise, plus sync of address book, calendar, etc.  I actually think that I know the reason that I am not able to send emails from Outlook as it has happened before when I have been overseas.  The reason, as advised by TPG tecnical support, is that the TPG mail servers treat my sendings as spam and block them because they are coming from an unrecognised  overseas server.  On the previous two occasions that this has occurred I have been assured by TPG that the issue has been fixed and will not occur again, but apparently it has not been which is very annoying.  I came through community forum to seek a solution as I am not prepared, once again, to incur very substantial international call charges whilst on lengthy hold waiting for a service technician.  I very much hope that you can resolve this issue for me, or if not, give me an email address that I can use to communicate with TPG technical support.   Nicholas. ...
