Notification Mail - Invalid Addresses

Hi Everyone,
I configured my smtp server as follows :

<entry key='mail.smtp.host'>smtp.gmail.com</entry>
<entry key='mail.smtp.port'>465</entry>
<entry key='mail.smtp.ssl.enable'>true</entry>
<entry key='mail.smtp.ssl.trust'>*</entry>
<entry key='mail.smtp.from'>example@gmail.com</entry>
<entry key='mail.smtp.auth'>true</entry>
<entry key='mail.smtp.username'>example@gmail.com</entry>
<entry key='mail.smtp.password'>*******</entry>

when I try to do a test send notification, I have this error:

Invalid Addresses - SendFailedException (... < NotificationMail:123 < NotificationResource:73 < ...)

thanks for the help

Error message is pretty self-explanatory.

Thank you @anton

I know but the emails are valid, and I activated the security parameters on gmail and then I tested with a php script (smtp) write by me and the emails are sent

If computer says it's invalid, then it's invalid. It doesn't lie. You must be missing something.

I'm sure that emails are valid and smtp from my gmail works. I don't know what's wrong :(

Can I have access to take a look?

Sorry for the delay, I was working locally, so I was looking for a way to put it online.

you can access this link : Link with user/user like login/password

Thank you

Well "user" is not a valid email.

the notification uses the user's email or the email provided in the configuration

No, it does NOT. Configuration only has "FROM" email. "TO" email is your user email address.

oh I'm really sorry, I did not pay attention, I always thought "TO" in place of "From".

Thank you very much Anton.
