Auto Responses SMTP relayed

[georgelazar]

Hi,

I have the following situation:

1. My OTRS is configured to send emails by default through a local email server.
2. Few queues are for outside customers and I'm using their external email addresses to receive the emails for those queues.
3. Externalk email addresses are assigned per queue and the agents reply using those external addresses as From.
4. Local mail server (Postfix) is configured to relay messages based on sender_dependent_relayhosts. For exemple if From field is matching external address: test@mycustomerdomain.com then it will relay the message to customer SMTP server.
This is to bypass SPF checks.

All ok so far but now I need to configure Auto Responses for each customer queue when a new email arrive/ticket created, whihc I did, and I also assigned the coresponding email addresses to the Auto Response From.
The problem is that the OTRS (v2.4.8 ) doesn't seems to send the full header to postfix in this case and then Postfix doesn't see From field and ignores sender_dependent_relayhosts. The email is sent using local smtp server as coming from my external customer and then arrive in Junk/Bulk folder because of the SPF check fail.

Please advice,

Thanks.
