Email delay through Gmail

Some people at my company are experiencing a severe delay when receiving emails sometimes. We recently had an email that was delayed for 41 hours according to the header.

My question is: how can I tell from the header where the delay occurred?

Here is the header info:

I've tried to block all personal addresses, but I've left something off that is needed for more info on what could be causing this, I'll be glad to share.

Thanks in advance!

To fix problem create DMARC record in DNS for domain example.com:

v=DMARC1;p=quarantine;pct=25;rua=mailto:[email protected]

Delay is between the Qmail SMTP and POP server.

Received: by [IPv6] with POP3 id xxxx;
        ***Thu, 21 Jun 2018 12:09:30 -0700 (PDT)***
X-Gmail-Fetch-Info: [email protected] 1 pop.secureserver.net 110 [email protected]
Received: (qmail xxxx invoked by uid xxxx); 20 Jun 2018 02:04:40 -0000
