[otrs] Attachment Problem in forwarded mail

Hi , We were testing otrs for couple of days.We have come across a scenario in which agent need to forward the mail from user to a man outside OTRS. Then we found that if there is attachments in mail its not going to recepient(man outside OTRS).The forwarded mail is going from OTRS to recepients inbox without attachement.How can I solve this.Plz Help. Thanks, Vimal
