Delayed outgoing mail in active queue

Question

I am stuck for some time trying to set up an email server. I've been mostly successful in my setup, but I am currently stuck at the following impasse: every time I send an email (regardless of queue size), my message will get stuck in the active queue for ~ 5 minutes, after which it will always be sent and reach it's final destination.

postqueue -p

(shows only one mail in the queue)

postqueue -f

... has no effect

I am running postfix 3.1.0, and dovecot 2.2.22 on Ubuntu 16.04. Also, I used iRedMail scripts for the installation. I can see from /var/log/mail.log that the mail is being stored in a queue by postfix, and I'm assuming there's another setting to set the time at which it will be processed. Any help would be most appreciated.
