emails take a LOT of time to be send

Customers are complaining that it takes a lot of time before they're receiving emails send by my server (using PHP mail). It used to work fine, but now it seems that it often takes hours. I did not modify the CPanel configuration, but I'm unaware if any recent (last 2 months?) automatic update may have done so. I tried to send a mail myself and got it right away, but after chatting with a client it seems that if doesn't always take such a long time (even though he suggested that sometimes he doesn't receive the email at all). Not sure if this may help: ]http://puu.sh/rwJz4/0db0b792d2.png
Any idea what can cause these delays?

  Hello, Could you search for the MSGID (available in the message headers) for one of the delayed messages in /var/log/exim_mainlog to see what's happening on the initial delivery attempt? EX:
  exigrep MSGID /var/log/exim_mainlog
  Thank you.
