Can’t Send Emails using PHP 7.4

    I tested my site with the new PHP 7.4. Using 7.4 I am unable to send emails. It works with 7.3.

    Obviously with PHP 7.4 just coming out, it’s reasonable for it to not be supported yet. I just thought I’d let you know that there does appear to be an issue.

    The debug info is below, for reference.

    Versions:
WordPress: 5.3
WordPress MS: Yes
PHP: 7.4.0
WP Mail SMTP: 1.7.1

Params:
Mailer: smtp
Constants: Yes
ErrorInfo: Invalid address: (setFrom) [email protected]
Host: localhost
Port: 25
SMTPSecure: string(0) ""
SMTPAutoTLS: bool(true)
SMTPAuth: bool(false)

Server:
OpenSSL: OpenSSL 1.0.2k 26 Jan 2017
Apache.mod_security: No
SMTP Debug:
Invalid address: (setFrom) [email protected]

    Thanks!

    The latest Cloudlinux PHP 7.4.1 build does have the correct PCRE 10.33, and emails from this plugin are sent with it.

    As the previous build with the old PCRE version was also 7.4.1, you’d have to check the phpinfo page to see if you have the correct version of PHP installed. (Or just send a test email. If it works, you’re good.)

    @bradbrownmagic, thank you for the update!

    7.4.2 has been released? I’m still at 7.4.1. ??

    No, it’s still at 7.4.1. The problem wasn’t PHP itself. It’s the version of the PCRE library that was bundled with it. (The PCRE library handles pattern matching. In this case it’s being used to validate email addresses. Version 10.31 is old, and has a bug breaks the email validation process.)

    Cloudlinux messed up and originally released their builds of both PHP 7.4 and 7.4.1 with the old PCRE library. They’ve now released a corrected PHP 7.4.1. So, there are now at least two Cloudlinux PHP 7.4.1 builds out there:

    PHP 7.4.1 with PCRE 10.31 which won’t work.
    PHP 7.4.1 with PCRE 10.33 which will work.

    I checked, working. Thank you. ??
