Email address in cc field

Hi,

I have ManageEngine Service Desk Plus 8110 connected to the mailbox (exchange 2010) ticket@mydomain.com and it works perfectly.

All users
write their requests for assistance via email at helpdesk@mydomain.com.

Helpdesk@mydomain.com

redirects all mail to ticket@mydomain.com.

When I reply to the ticket I find always address helpdesk@mydomain.com in CC and I have to delete it manually. (wrong)

If users would write directly to ticket@mydomain.com when I answer the ticket can not find the address in CC helpdesk@mydomain.com. (right)

Of course if you go into outlook mailbox "ticket@mydomain.com" (stopping the mail fatching) if I do a test response by client outlook can not find the address in cc helpdesk@mydomain.com. (right)

So the rule redirects it works fine in outlook, but when ManageEngine fatching mail and reply to an email, it puts the address helpdesk@mydomain.com CC field
I do not know if I can explain it well, sorry for my English.

Thanks

Daniel
