@shume . TPG Post Office is not a mail client. It is "webmail" which is accessed by your browser. It already uses SSL/TLS.

In Post Office, Settings, can  you check that Account Name is correct (it can't be changed). And From Address is correct. In most cases, both are the same value.

You say error happens when using Contacts.

Does it happen if you Reply to an email?

Does it happen when you try to send to an email address which isn't a reply or contact?

You can send an email to postmaster@tpg.com.au detailing your problem. You'll need someone else to send it for you or use another mail system (gmail, hotmail). 

Provide an exact date/time of occurrence, your email address, address you're trying to send to.

Include a screenshot showing the error message with the email you're trying to send.

The Mail app on iPad might be a victim of the problem with Post Office.

Thanks everyone for your help. I phoned tpg and got it sorted, although still doesn't work from my iPad.
