Helpdesk email issues

[krisd32]

On our setup for hap i'm using the email address itsupport@school.sch.uk and that works fine when i'm creating tickets from the admin account but when i try to create a ticket with an actual user i get a "550 5.7.1 Client does not have permissions to send as this sender" error message. and seems as we are using the county email system i can't administer the exchange server at all. problem goes away if i have the itsupport email set in active directory for each user but obviously that won't keep the users involved in the loop. would it possible to implement in the system a way of always sending mail out of the system with out cross referencing the AD email address. so it was always sent as the itsupport email and not trying to send as the current logged in user?
Hope that makes sense. thanks in advance.

Unfortunately not, the system pulls down a lot of information from AD related to the user, one property is the mail attribute. It's all tied into the AD Authentication.

why can't you ask them to give you send-as rights for that user. It only takes about 1 min to do.
