the mail is going to proper user it the mail is To/CC but not bcc.The
exact problem I am having is that the mails even send to To/Cc are
going to all the users.Suppor there is a single mail going to john and
marry then john and marry will receive 2 copies of that mail whereas
they should receive only 1 mail each.

Is there any other utility or program  through which i can download
the mails for users from the catchall mailbox without any issues or
problems.

Thanks & Regards
