"Send as ..." Checkbox in Shared Mailbox

[bgszim]

Hi All

I've updated from Zimbra Open Source 6 to Network Edition 7.

I have a shared Mailbox which is used as a "Mail archiv" (normal Mailbox). Every user has this shared mailbox as a public folder attached (additional to his personal mailbox). Since i've made the update to version 7 when a user forwards or reply to a mail which is inside this shared Mailbox there is a Checkbox under the "Subject" Field. This checkbox is checked per default and has the label "Send as share@mydomain.com". So if i user does not uncheck the checkbox the mail has the "share@mydomain.com" as the sender and not the personal emailadress. How can i change that default value of this shared publich folder so this checkbox is unchecked by default?


Thanks + best regards
