Mail with mail merge not sent to own address

I created in Calc a list of persons with their e-mail adres. This includes myself.
In Writer I composed a document with reference to the calc file, and have my provider’s smtp settings for my own emailadress, and that tested OK in the LO Writer options.
Now I send the mails and they go through, I know because:
two addresses were rejected as invalid (my fault)
and
someone reacted to the mail.
But I notice two things:
The mails sent do not appear in my Sent folder
and
I don’t see my own mail coming in at my own mail adddress.
Is this behavior to be expected or not?
