[Exim] Bcc problem ! - Bcc headers in Body of mail !

Hi All,

I am not quite sure what this is at this point in time, but I think it could
become a problem as it is the second time it has happened.

One the two occasions, two of our staff has bulk email out their retail
customers. They all add up to around 1000 contacts. which btw, if anyone is
interested, makes the mail header over 72k big.

All the contacts were in Bcc: plus 'the staf themself' in the To:.

I havent had confirmation from ALL customers, but so far the staff had three
customers inform them that their mail outs contained all the hundreds or
email addresses in the body of the email. (which should have been in Bcc
instead)

I have looked up the archives of the list, but it is not currently making
any sense to me.

I was wondering if anyone has had this problem before ? And if so, how do
you fix it ?

Thanks for any input.

Regards

Chris G.
