Very bad mail queue statistics

Does anybody here know why only less than 60.7% of the mails were in the queue less than 1 minute, while more than 30% were in the queue for more than one day, on this cPanel server?

Time spent on the queue: messages with at least one remote delivery

Under 1m 2280 60.7% 60.7%
5m 95 2.5% 63.2%
15m 44 1.2% 64.4%
30m 9 0.2% 64.7%
1h 3 0.1% 64.7%
3h 36 1.0% 65.7%
6h 15 0.4% 66.1%
12h 14 0.4% 66.5%
1d 11 0.3% 66.8%
Over 1d 1248 33.2% 100.0%

Something is really wrong here.

Thanks
John
