Receive and reading confirmations can be set in several ways. For new messages the option is set in
Account > Properties > Templates > New Message and tick the Receipt Request and Reading Confirmation boxes to turn them on, and untick to turn them off.
For replies and forwards the option needs to be set in the Reply and Forward Templates (again found in
Account > Preferences > Templates). Open the Reply and Forward templates in turn and add the following two lines to both templates:
%RCPTCONFIRM%-
%READCONFIRM%-
These are macros which will ensure your replies and forwards always request a Receipt and Reading Confirmations. You can add these macros into any reply and/or forward template anywhere, e.g. in folders, address book entries, or accounts.
Hope this helps.
