What sieve server are you using?

As I'm running Dovecot as MDA, Sieve is integrated as dovecot-managesieved ( v2.2.13)

Is this the information you needed ?

Yes, thanks.

Does it work when you actually specify a subject?

No, still not working.

I would need you to gather one of those two informations:

1. Ether the JSON payload when submitting /SOGo/so/USER/Preferences/save (you can get it from the developer tools of your browser);
2. Or the Sieve traffic that you could sniff with tcpflow.

I've got the exact same error on 3.2.4 freshly upgraded.

In fact seing what the user does helped a lot, they think the "Custom subject" checkbox is self-sufficient and they don't naturally enter the real subject content in it. They think maybe the "auto reply message" box contains the subject and message.

We are using the French translation which doesn't even mention the "${subject}" variable and is really misleading.

Maybe you could just check that the subject is not empty when checking the checkbox ? (I've tried putting a subject and this makes the error disappear)

Your Sieve server probably doesn't support variables.

Open your JavaScript console from the Preferences page and type:

<pre>sieveCapabilities</pre>

Show me the result.

3.2.4 does validate the subject (see https://github.com/inverse-inc/sogo/commit/c9467e1ce3258ecc8f8b36447b94c30165368f55).

I tested it with 3.2.6a: I always have to save the settings twice: The first time I get the described http 502 error (and the sieve filter will not work although it is created correctly on the dovecote server). The second time the settings will be saved successfully and the filer works as expected. It does not matter, if a subject is set or not.

Which information/files do you need?

Please capture the Sieve traffic to see the full conversation with the server.

<pre>tcpflow -i lo -c tcp port sieve</pre>

It's probably because you enabled the "auto reply subject" checkbox but haven't specify an actual subject. This is no longer possible in the latest versions of SOGo.

I just ran into this issue with a user who enabled "Auto Reply Subject" but didn't enter any text.

In this case the option to save the vacation message is grayed out (which is good) but if the user navigates away from the page they get the dialog "Unsaved Changes Do you want to save your changes made to the configuration?"

If the user selects "Save", a connection error dialog is displayed but the vacation message appears enabled in the web GUI even though the sogo.sieve file is not updated on the mail server.

I'm running SOGo 3.2.9 201705100648

Thank you.
