Hmm...try to add the following clause to your INNER JOIN
AND A.date = B.Date

Like this :

INNER JOIN view_sent_messages B
              ON A.theme=B.theme
            AND A.receiver=B.receiver
             AND A.date = b.Date
            AND B.date=ANY (A.dates)

Doesn't work. I get the result

 sum | theme  |   receiver   |                                     dates

 Which is not correct. The wrong values (  red colored ) remain as before
 adding the clause. And now it is summed  the counter's values per day
 ( first day of dates array ).

I have not your data here, so I am not sure if it'll work.
Also, Ive never worked with vectors on Postgres. I am assuming ANY() returns true if B.date is on the vector A.dates, is this correct??
Correct.
