I've set up an email within my cpanel and am using roundcube as my email client. This is a fresh install and am having issues with recieving emails. I can send emails from my roundcube to an external email successfully. If I try to reply (using the same external gmail email account I sent it to)it fails to send the reply with the above code.
Im extremely new to setting up a server email. Any help would be appreciated.
Thanks in advance
If you setup Roundcube with the SMTP details check if any of this other issues in cPanel are causing the issue: https://support.cpanel.net/hc/en-us/articles/360058963474-550-Please-turn-on-SMTP-Authentication-in-your-mail-client
