vacation response empty from /usr/sbin/exim -t -oem -oi -f <> -E1ucjOO-00000006Yc9-2gr3

Hi all,

When sending a vacation (auto-reply) message, the server sends out the response email without a sender:

/usr/sbin/exim -t -oem -oi -f <> -E1ucjOO-00000006Yc9-2gr3

In the Exim uservacation log, the From: address is present (e.g. email@address), but Gmail rejects the message because the sender is missing.

What can I do to make it work?

Thanks!

Hello,

You might try and use Sieve filtering managed in RoundCube: https://help.poralix.com/articles/creating-autoresponder-via-webmail-in

Sieve doesn’t work either.

The solution in this case is: the server’s hostname is used as the sender, and this is what Google (and others) also checks.

Therefore, you need to create a valid SPF record for the server’s hostname – this way, the email will be accepted.

Feel free to update exim configuration to rewrite sender per your needs then. I don't have a solution by my hands right now, but I did something similar a while ago.

Thank you for your help. Creating an SPF record for the server’s hostname solved the issue, without needing to modify any Exim configuration.
