[SOLVED] Auto responses not working, blank sender

[Guybrush]

Please help,
I have just upgraded to 3.3.4. I have attempted to configure auto-responses for the first time.
The problem is that the system is trying to send the messages with a blank from field.

"
Feb 3 13:20:05 <hostname> OTRS-otrs.PostMasterMailbox.pl-10[11655]: [Error][Kernel::System::Email::SMTP::Send][Line:122]: Can't use from '': 554Mail from rejected for policy reasons.#012! Enable Net::SMTP debug for more info!
Feb 3 13:20:05 <hostname> OTRS-otrs.PostMasterMailbox.pl-10[11655]: [Info][Kernel::System::Email::Send] Error sending message
Feb 3 13:20:05 <hostname> OTRS-otrs.PostMasterMailbox.pl-10[11655]: [Error][Kernel::System::Ticket::Article::ArticleSend][Line:2078]: Impossible to send message to: <email address> .
"

As a test, I have tried explicitly specifying the address in Article>SendAutoResponse (line 2897) but this has no effect.

The auto-responses are not accepted for delivery. However, normal replies are working as usual.
Many thanks for your assistance...
Best regards
Guybrush

Notification Sender is blank

ask your mail server guys for assistance

Dear Crythias,
Thank you very much for your swift response.
For the benefit of others, the setting I needed is under Framework -> Core::Sendmail >> SendmailNotificationEnvelopeFrom
It might be useful to include a comment in your documentation to remind the admin user to check this setting.
However there is a field on the autoresponse "Auto response from:" that appears to define the address from which the notification is sent, this does not seem to be used?
All the best

this setting only needs to be set if <> as a sender is not allowed (which is an violation of the RFC). Also setting the envelope from might cause other issues as now all mails will use this envelope from.

For changing documentation you can send a pull request via github

Actually I think it would be best if the system behaved as suggested by the option "Auto response from:" in the auto response object.
As I see it, it is unlikely that the user would want emails to come from <> or from a single address, as different addresses for different queues would be a common set-up.
Why isn't this setting honoured? It doesn't appear to be used at all.

[jojo]

you now the difference between
mail from and from in the SMTP dialog?

an envelope from might be different from the from visible to the receiver.

All Notifications and aut replies are sent with an empty envelope from (which is RFC compliant for this use) to prevent backscatter

[Guybrush]

I see there is some reasonable explanation...
Thanks again for your help.
Have a great day
