That is because you are not using them properly.

Please elaborate.

Please show your actual code.

What is so hard to understand about the SASLMechanisms?  TIdSMTP has a
SASLMechanisms property that is a collection of supported SASL entries.
Simply add a new entry it to, and then assign the item's SASL property to
the desired SASL algorithm that you want to use.

That code is completely wrong.  You do not create the TIdSASLEntries
component yourself at all.  TIdSMTP has its own instance that it owns which
you should be using instead.  As such, your code should look more like the
following instead:

    CRAMMD5.UserPassProvider := TIdUserPassProvider.Create(CRAMMD5);
    CRAMMD5.UserPassProvider.Password :=  'thepw';
    CRAMMD5.UserPassProvider.Username := 'theid';
    IdSMTP.SASLMechanisms.Add.SASL := CRAMMD5;
