553 Sender envelope rejected

[ebhannes]

Hi,

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.

Thanks for your response.

This is the spf policy of the recipient:
[v=spf1 ip4:some allowed networks and ip addresses -all].
As far as i know -all restricts redirecting and there is nothing i can do about it, except nasty forwarding.
Please correct me if i'm wrong.

bye
Hannes
