User Vacation Message
« on: April 02, 2018, 07:11:01 PM »
Good day!

I have an issue where I have turned on vacation message but for some reason when the auto message is sent outside our domain it's broken:

Subject:   Re:Auto Reply
Date:   2 Apr 2018 13:05:19 -0400
From:   User@domain.com
To:   srs0=cdhtnb=gx=gmail.com=bri.amesse@domain.com

What makes it become:
srs0=cdhtnb=gx=gmail.com=bri.amesse@domain.com

Is there a way to fix this issue? As the messages don't get sent out.

Brian

Well only guessing here as we have only partial and onfuscated info : how the original mail delivered? Is it via a fetchmail, getmail mechanism or any mail transfer / mailing list to this account?

My guess would be for the last one, and the email conversion is to allow to get around the dkim check by using the domain of the transfering box.

If so the vacation message should be set on the original box.

Thanks for the response.

From what I gather it is actually delivered via fetchmail.

I will show the whole source of the sent mail from my gmail:

It seems to me the return path:

Return-path: <SRS0=CDhTNb=GX=gmail.com=bri.amesse@epls.ca>

Is what is creating the issue.

As for why it is read like that, I would love to figure out.

Re: User Vacation Message

this is because of https://en.wikipedia.org/wiki/Sender_Rewriting_Scheme
I thought only From should be reencoded, but it seems that it happens also on Return-Path.

Then vacation should recreate the original email. I found http://search.cpan.org/~shevek/Mail-SRS-0.31/lib/Mail/SRS.pm but was not able to get it working to reverse the string to regular email, which  seems to be bri.amesse@gmail.com




EDIT:
- the Return-Path has been added by qpsmtpd (print MF "Return-Path: ", $transaction->sender->format , "\n";) but this seems that your message has traveled quite a few, can you explain the part you know / have access to?

From the list of transaction the first one acting on the header is the Exim box "s029.panelboxmanager.com", which reencode the return-path without it to be needed. Can you act there ?

see https://www.libsrs2.org/srs/srs.pdf

the issue is not the return path but rather a misconfiguration in term of DNS or on one of your SMTP servers (likely  s029.panelboxmanager.com).

Return-path: <SRS0=CDhTNb=GX=gmail.com=bri.amesse@epls.ca> is correct.
epls.ca should be handled by s029.panelboxmanager.com as this is the one which added the header. It is the one able to match the orginal sender and with its own hash to see if the bounce / vacation message is legitimate.

so if you think that this is not right this is likely that your received a bounce, because epls.ca is configured to point to your sme vmsme.epls.ca  which does not know anything about this SRS.
