You need to tail your exim mail log (Linux: /var/log/exim_mainlog) and your apache error log (/usr/local/apache/logs/error_log) and look for errors when sending out email. For incoming you obviously only need to watch the exim log.

sending email as Nobody was not disabled from WHM was it?

Also, have you recently turned on phpsuexec?

You should follow chirpy's advice and tail the logs. it will tell you more, however if the above changes were made, this could account for your problems. (possible. not probable)

If you have root access login then click tweak settings near the top and check this is NOT ticked:

Include a list of Pop before SMTP senders in the X-PopBeforeSMTP header when relaying mail. (exim 4.34-30+ required)

If it is untick it
