problem arise, when redirecting mail to a mailbox which belongs to the same domain like the sender.
Some of our employees have two mailboxes. One companys mailbox (to which scalix server belongs) and a second box at a customers company (as an external employee)
When you or someone else from the customer company mailbox send some mail to some mailbox in our domain, which is redirected to customers company mailbox, mail is rejected with following message:
Code: Select all
external.Employee.A@customercompany.com
SMTP error from remote mail server after MAIL FROM:<prvs=347446ff22=internal.Employee.B@customercompany.com> SIZE=5868:
host mx1.customercompany.com [153.153.153.153]: 553 Envelope sender <prvs=347446ff22=internal.Employee.B@customercompany.com> rejected
Looks like this
Code: Select all
unknown.employee@customercompany.com --------> employee.A@company.com (scalix domain) -----retain in mailbox
|
| redirect
V
external.employeeA@customercompany.com <-------X (rejected)----------
In my opinion this is due to Sender Policy framework or the use of SenderID. But how to avoid this without switching to forwarding?
Annoying when forwarding the mail is that original mail isn't display inlined, only attached. Also the sender changes to the first adressee, which is not quite comfortable.
