ESPOcrm not sending mail, SSL error

[jensbee4]

Hi,
since one or two days we cant send Mails from the crm. I get the following in the logs:

[2019-10-10 09:44:53] Espo.ERROR: (0) Could not read from smtp.office365.com; POST /api/v1/Email/action/sendTestEmail; line: 306, file: /app/code/5.7.1/vendor/zendframework/zend-mail/src/Protocol/AbstractProtocol.php [] []

Because this could be an php error i post here first. Sending Mails over Office365 over the Cloudron in generall works.

Someone from the EspoCRM Forum discoverd that i need to enable smtp auth. With this i can send mails.

Background for not enabling smtp auth:
We use Office365 as Mail System. Because we run some Apps in our cloudron i marked the Server as trusted host in the office365 exchange system. With this all the apps can send Mails without entering Mail Server data.
Topic is solved for me.
