 * Hi [@ranbac](https://wordpress.org/support/users/ranbac/),
 * I’m sorry for any trouble! There shouldn’t be any issues with PHP 7.4, though,
   and we even encourage all users to use the most recent PHP version available 
   through their hosting provider. So we’d definitely like to help get to the bottom
   of this.
 * In order for us to help you out further, could you please share any details about
   the issue you’re seeing [over in our support forum](https://wordpress.org/support/topic/wp-mail-smtp-support-policy-2/)?
   Specifically, please let us know:
 * – Which mailer you’re using
    – Details on what happens when you try to send a
   test email (under WP Mail SMTP > Settings > Email Test), including the full error
   log if this fails – Any other errors you’re seeing (including screenshots, if
   possible)
 * Thanks!

 * I’m using Other SMTP.
    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.

 * Hi [@ranbac](https://wordpress.org/support/users/ranbac/),
 * Unfortunately, this is most likely a bug in PHP 7.4 and specifically in its bundled
   Filter extension and its PCRE library (the one that parses and validates emails).
 * See this support thread for more information: [https://wordpress.org/support/topic/cant-send-emails-using-php-7-4/](https://wordpress.org/support/topic/cant-send-emails-using-php-7-4/)
 * You should downgrade to PHP 7.3 and wait for a fix for PHP 7.4.
    It might be 
   a good idea to notify your hosting support, so they will monitor the correct 
   version of the PCRE lib included into the next PHP 7.4 build that they deploy
   to all of their clients.
 * PS I hope you will reconsider the rating of the plugin 🙂
