Automatic emails stopped working after V20-upgrade

[gurksallad]

We have setup that a mail is sent out as soon as a customer has signed the proposal. These mail stopped working and I’ve been trying to find out why and I found some errors in the logs.

First, here is the log when sending a test email (I have replaced the actual email adresses with something else):

Here’s the log file when a proposal is signed:

Somehow, the “from=” gets empty here and it seems this is the reason it fails. Sending test emails and sending invoices (or anything, really) with email from within Dolibarr works fine, but the automatic notifications have all stopped working.

I have created a bugreport in #33338.

which dolibarr version?

which notification triggers do you have?

I use proposal validated, order validated and invoice paid - I run v20.0.2 and have not experienced issues

V20.0.2. I use the following triggers:

I found the error. After the upgrade, the “Sender email (From) for emails sent by the Notifications module” field was empty. After refilling it, notification works again.
