after upgrading from NC 13.0.6 to NC14.0.1 the installation comes back with all sorts of unexpected issues.
One of these issues is:
Use of the the built in php mailer is no longer supported. [Please update your email server settings ]
on one hand this is annoying since php mailer was working in all versions before and there might be good reasons to use it instead of a SMTP server.
on the other hand… the updater is checking all kinds of stuff before upgrade (or pretends to do so) but there isn’t even a warning that a core feature will be disabled by upgrading.
Further: the manual clearly states (https://docs.nextcloud.com/server/14/admin_manual/configuration_server/email_configuration.html):
Supported methods are php, smtp, sendmail
Nextcloud version (eg, 12.0.2): 14.0.1
Operating system and version (eg, Ubuntu 17.04): 18.04
Apache or nginx version (eg, Apache 2.4.25): Nginx 1.14.0
PHP version (eg, 7.1): 7.2
The issue you are facing:
Use of the the built in php mailer is no longer supported
Is this the first time you’ve seen this error? (Y/N): y
Steps to replicate it:
- run Nextcloud 13
- upgrade to NC14.0.1 using updater app
