    Hello,

    I set SMTP Port 465 (my server supports ssl/tls) and i choose tls.
    and i got this msg:

    An issue was detected.
This means your test email was unable to be sent.

Typically this error is returned for one of the following reasons:

Plugin settings are incorrect (wrong SMTP settings, invalid Mailer configuration, etc).
Your web server is blocking the connection.
Your host is rejecting the connection.
Recommended next steps:
Triple check the plugin settings, consider reconfiguring to make sure everything is correct (eg bad copy and paste).
Contact your web hosting provider and ask them to verify your server can make outside connections. Additionally, ask them if a firewall or security policy may be preventing the connection - many shared hosts block certain ports.
Note: this is the most common cause of this issue.
Try using a different mailer.

    on my csf have set
    PORTS_smtpauth = 25,465,587
    PORTS_eximsyntax = 25,465,587

    Why i got problems with your plugin?

    Hi @b_dark,

    Thanks for reaching out! The error indicates that your web server is blocking your SMTP connection requests.

    If your SMTP configurations are correct, it could be your server’s Firewall or ModSecurity rules are blocking your SMTP connection.

    Please get in touch with your hosting support with the full error log, and they should be able to assist you further.

    I hope this helps. Thanks!

    Hi @b_dark,

    As I have mentioned earlier, you need to check that with your hosting support.

    Your server may have been configured in a specific way, and you can request them to open preferred ports.

    I hope this helps. Thanks!
