Thank you for the quick reply and clarification. I was not
aware of this behavior before.

Everything is normal (counted) when the file is rebuilt
at 5120 bytes.
The problem seems to be when, upon migration to dovecot,
the maildirsize file was already over 5120 bytes (5128,
even 5148, normally consisting of one file entry line).
With this size, dovecot behaves as if there is no
maildirsize file present in the user's maildir.
