I've not found it, but is there any way to turn off giving requested receipts globally? I'm aware they can be turned of on an email by email basis, but I want stop all of them.
Two reasons, I hate the pressure as a recipient then knows you've read it, and expects a prompt answer, and it also serves to notify spammers that the address they've used is valid.
I'm using the 'advanced email', and was previously using the Madasafish one which does not give receipts.
Fixed! Go to the fix.
