My solution was in some ways the “obvious” one, which was to configure my SMTP server to accept the sent value.

Thanks Gregor. I found a different workaround/solution so this should now be unnecessary for me now, however for future searchers, I believe it should be wp_mail_smtp_mailcatcher_smtp_send_before (no pre), based on the code in src/MailCatcher.php.

Looks like PHPMailer supports setting the $Helo configuration value: https://phpmailer.github.io/PHPMailer/classes/PHPMailer.PHPMailer.PHPMailer.html#property_Helo

I have the same issue. However, my canonical domain name is https://www.example.com, so I cannot change the nginx settings.

Is there a way to override the EHLO server name without modifying the server_name in nginx?
