Did you verify that TIdSMTP is actually transmitting any data over the
connection? You can use a packet sniffer for that. If it is indeed not
sending anything during that hour, then it sounds like TIdMessage is having
trouble encoding the attachment (it is probably stuck in a loop internally),
or is not sending all of the necessary commands to the server, or the server
is not responding to them correctly.
