Mail not sending since 1.11.20

[RobinKal]

Describe
After the migration from 1.11.18 to 1.11.20, mails stopped to be sent.
PHPMailer works as intended, we tried with a test script file.

To Reproduce
Steps to reproduce the behavior:

1. Use the same configuration (app/config/mail.conf.php) on both versions
2. Send a mail through the app
3. Check web server logs

Expected behavior
Mails being sent to the destinator

Screenshots
Nothin is being sent, error is :
Got error 'PHP message: ERROR: mail not sent to testmail testmail (*) because of SMTP connect() failed.

**Server

• OS: Linux Ubuntu 18.04 AND 20.04
• Version of Chamilo: 1.11.20
• Version of PHP: 7.4

Hi @RobinKal
Can you try with the changes from 9180710?

Hi I confirm, it works fine.
Many thanks for the fix.

I am also having this issue on my mac with mail not being sent since upgrading to 1.11.20
I have not applied the fix as yet. That will be technically difficult for me so I'm waiting to see if my host can do it.

[riesaau]

I applied the fix (my host did it for me since I am not a programmer). The reset password no longer gives me a failed message but the email never arrives. Also the announcement tool will only send emails to myself and not to the other emails that it was meant to send to.
This issue now seems similar to this one. #3625

[riesaau]

There was a delay but the email reset message eventually came through okay. so it is only the announcement tool which fails to send to anyone else except myself.

[riesaau]

One person on the announcement got the email from the tool besides myself. so I will have to look into the issue more.

[riesaau]

I think it is all working now since the fix. Thank you.

Have the same problem as mentioned above... I did make the fix as mentioned, and that did actually worked - now able to send mail if someone missing password... Also sending mail - if somebody buy a course (extension buycourses)..
But - But....
If I assign a course to a student - it does not send any mail about the assignmet to the course.
Also if a student registred to the portal - they dont receive any email - with username and password.
Any surgestions ??
