[Evolution] Message Receipts option ignored?

["W. Martin Borgert" <debacle debian org>]

Hi,

I have set my Message Receipts as follows:

Send message receipts: Never

However, when I read a message, the sender gets a read receipt,
which I want to prevent. Is this the correct configuration
option or do I have to set something else?

I use Debian with evolution and evolution-exchange 2.30.2-1.
Server is MSexChange idontknowwhat.

Many thanks in advance!
