PHP-IMAP Extension replacement/alternatives

Hello,

I switched to php8.2 remi.
Unfortunately it's worst.

Sending SMTP doesn't work anymore:
2024-04-29 12:42:17.871 ***** ERROR ***** [V10.3.6] PHPMail error : SMTP connect() failed. github.com/PHPMailer/PHPMailer/wiki/Troubleshooting
2024-04-29 12:42:17.871 ***** ERROR ***** [V10.3.6] PHPMail debug :

Troubleshooting tells to not mix SMTPS or STARTTLS but there is no way to select one of these in Projeqtor 10.3.6.

After switching to PHP 8.2, the first error was :
2024-04-29 10:58:25.811 ***** ERROR ***** [V10.3.6] cause = nl2br(): Passing null to parameter #1 ($string) of type string is deprecated

As the first null parameter was username, I set username/password and error became 'smtp failed to connect'.
I followed troubleshooting all was ok except missing sendmail (not neede in php 8.0).
But still error smtp.
I have deleted user/password and it WORKS. PHP8.2 need sendmail.

It seems when you set username/password in Projeqtor, it activates encryption but you cannot select STARTTLS against SMTPS. I don't know how Projeqtor select one.
I hope this is not based on port number because we use a custom port xx25, for internal mailing.

I do not use localhost and I needed sendmail in 8.2 like in

I tried tls:// to use STARTTLS but smtp failed
