This is very odd. I *used to* have my cell phone number in whm contact (edit setup and contact manager) to receive server notices. I removed it long ago, yet oddly I get get "statscheck, server overload" emails to my cell phone from my RESELLER clients's username!
Also, second issue. One client cannot login to ftp (only one user with this problem). I restarted ftp, switched from pure to pro, back to pure (none worked). I reset his password. The ftp is his cpanel main username, not a new created ftp account so it is username as the username, not [email protected] for ftp username.
Domain is in /etc/localdomains too. Still getting 530 auth error.
