  • Hello,

    I don’t know how you find this log. Can you tell me how to find it?

    I seem to have the same issue with mailjet as SMTP server

    Hello @kundaweb12
    Inside the plugin
    After sending a test email, if sending is a problem, you can see the log at the bottom of the page.

    Hi @mbagheri,

    Thanks for reaching out! Most probably your server’s Firewall or ModSecurity rules are blocking your SMTP connection requests. Could you please get in touch with your hosting support with the error log and they should be able to assist you accordingly.

    I hope this helps. Thanks!

    Hi @kundaweb12,

    When you send a test email from WP Mail SMTP > Tools area, you should be able to see the full error. Here’s a screenshot of the option to get a full error log. This will provide you with an idea of what might be going on.

    Thanks!

    Hello @darshanaw
    thanks for your help
    This was because the mail server and site domain were the same
    I solved my problem by changing the phpmailer file and changing the domain address
