Server configuration

Operating system:

Web server:
Apache 2.4.34
Database:
MySQL 5.6.40
PHP version:
7.2.9
ownCloud version: (see ownCloud admin page)
10.0.9.5
Updated from an older ownCloud or fresh install:
9.x
Where did you install ownCloud from:
cpanel

an email is sent and verified when a user testmail is tested.
no folder updates or any other notifications are sent.

How did you configured this?

I am using smtp theclients normal smtp server and the test works.
not sure what other settings need to be done.

I had to change list($name, $domain) = explode(’@’, $email, 2);
$domain = idn_to_ascii($domain, 0, INTL_IDNA_VARIANT_2003);
in the mailer and message php config files to get the system to save the email addresses.

I can give you access to the server to check if needed.

Have you installed, enabled and configured the activity app?

I see there is a nottifications app that is applied , the apps that are active are the basic ones that come with the softalicious cpanel installation.

How do I install the activity app.

Go to market - in ownCloud - and install the app as an admin user

thank you , let me give that a try.

Further question, I have a client that is looking at using owncloud , and will upload approx. 15 000 pdf a month , will OC handle this type of volume.

I suppose, but many files will take a while to sync if you want to sync it at once.

thanks
They will be uploading a few 100 per day , will do a test run on a test setup for them.
