Email in Queue, SpamAssasin error

If I set emails to be sent via the Queue, and allow a small number of emails to be sent every time the cron job runs, I run the risk of SpamAssassin marking my email with the “DATE_IN_PAST_03_06” flag (for example).

If I understand this correctly, this is because Mautic “creates” the email, puts it in the spool folder and then sends it later, and ofc if I “spool” 1,000,000 emails and only allow for sending one per minute, they will be old.

Am I right in the assumption (that it works this way)?
