Hey,
I have been using cwp from 2012 and with google cloud from 2019 but my any php application's SMTP script does not work. usually I used G Suite. even I also contacted paid support but they unable to provide me support, They told me that Google cloud block 25 port so mail will not work but how could it is possible? WP Mail SMTP. plugins able to manage send and received mail in same server.
There have anyone who can help me to fix it? either I have to switch to aws or other but I believe defiantly there have some solution in cwp
