AWS SES processing delay

We are sending emails with SES.

There seems to be delays in emails arriving for some users. For other users, emails arrive almost instantly. I've switched on notifications and can see the processingTimeMillis is extremely high for some emails:

{
    "notificationType": "Delivery",
    "mail": {
        "timestamp": "2016-04-14T14:02:50.000Z",
        "source": "[email protected]",
        "sourceArn": "...",
        "sendingAccountId": "884660938610",
        "messageId": "...",
        "destination": ["[email protected]"]
    },
    "delivery": {
        "timestamp": "2016-04-14T14:19:29.072Z",
        "processingTimeMillis": 999072,
        "recipients": ["[email protected]"],
        "smtpResponse": "250 [email protected] Received OK",
        "reportingMTA": "abcdef.smtp-out.us-west-2.amazonses.com"
    }
}

I've read around online but haven't been able to see what may cause these types of delays.

Email addresses and domains are all verified.

I've removed account specific information from the above. The processing time value was not changed.

Thank you to those who commented, led me to find the answer.

There were several email servers which were delaying the emails from being delivered to the inboxes.

SES was sending these correctly and quickly however once they arrived at the destination server, this was taking time to process and release.
