Can you please explain the relationships between triggering sensitivity, alarm delay and post delay (especially that last one!)? Thanks.

Sensitivity - is related to size of the moving object (changes before camera) to be reached in order to alarm (to call destinations).

Alarm delay - is to avoid false alarms. Any motion that is shorter than specified amount of time (for example 1 second) will not be detected.
For example, bird flying by, light condition changes, etc.

Post delay - amount of time to continue recording after motion is finished.
It could be used to continue recording multiple motions with small intervals between them - into one video file.
