Hi dears,
Since a few time, don't know how much, I get this error when requesting password ou ID.
If I switch configuration to PHPMailer the message is sent, but I need to use SMTP for other reasons.
My smtp server is Elasticemail.com using SSL/TLS port 465.
If I try those parameters with Thunderbird it work.
If I just send a test from Joomla configuration page, it work.

So I guess the problem comme from Community Builder, but don't understand where, no mail configuration inside CB.

Any idea to help me ?
Thank's a lot

Thank's for your answer.
I read the page error, but nothing is speaking to me for that problem.
If the Joomla email configuration was wrong, "send a test message" would not work, isn't it ?
Acymailing work perfectly (an send a test), so DNS configuration of hosting provider is working, isn't it ?
I tried 587 STARTTLS, doesn't work more, nore smtp.elasticemail.com:465

Only a request to the identifier ou password doesn't work, so I guess the problem is only in CB.

I have Joomla 3.9.10 and CB 2.4.2. I read somewhere in the forum someone has the same problem, since CB 2.2. But he speak about none secure smtp config. That's why I tried SSL instead of not secured 25, but it is the same.
Regards

I tried
SMTP Host: smtp.elasticemail.com also tried smtp.elasticemail.com:465
SMTP Port: 465 also tried 587 and STARTTLS
SMTP Security: SSL/TLS
SMTP Authentication: Yes
SMTP Username: (elasticemail username)
SMTP Password: (elasticemail password)

When I use PHP Mailer I received the mail with "via mail-out.cluster023.hosting.ovh.net " in the from field.
