On some appointments I set a mail reminder to confirm my participation in addition to display and audio reminders. For the mail reminder I set mail address, message text and when the it should be sent.
Regrettably Kontact does anything a bit different as planned.
a) Instead of the configured message it sent a remind note to.
b) This remind note is sent every time an other reminder is falling due. Example, an audio reminder is set 2 hours before event start - so at the same time (2 h before) with this a remind note will be sent. Embarrassing in face of customers and suppliers.

Reproducible: Always

Steps to Reproduce:
1. Configure a future appointment with some reminders. One of them must be a "Send email" reminder type.
2. For this one choose when, the email of the partner (it can also be your own) and edit a message (i.e.: I'm appreciate to participate on the next briefing) 
3. Wait for the set reminders and you will note what happens wrong.

Actual Results:  
A email reminder (not the message edited) is sent and that also when other kind of reminders falling due

Expected Results:  
1. The email sent contains the edited message (not a reminder note)
2. The email should be sent only for the "Send email" reminder (not also for other reminders)
