IMAP has the Internal Date Message Attribute, which ostensibly tells
you when the message was delivered. A good idea, poorly thought out
and even poorer in implementation, if you will.
It's left entirely up to the IMAP server as to how it wants to
generate an IDMA -- the standard says that it SHOULD (not even MUST!)
be the delivery date and time for messages delivered over SMTP -- and
for that reason it's about as reliable as delivery status
notifications and read receipts, an "only rely on this if you know
everyone involved uses the same software" sort of feature.
