Email problem with crontab jobs

[henkbart]

Hello,

I have a strange problem.
Once a week crontab sends statistic emails about all the domains.
These emails are also send to the admin of the server.
The headers are fine, but the emails are droped in the wrong email-box and are going to the wrong person.

for example : the admin email is : admin@server.com
The header showing that the messeage is delivered at admin@server.com but the message ends-up in another mailbox (user@server.com).

This is very strange. Sometimes everything goes well, and another time none of the messages is coming to the correct mailbox.

Does anybody knows what is going wrong???

Thanks
