550 "REJECTED - Bad HELO - Host impersonating

[Administrator]

Hi Guys,

When trying to send emails, at times you receive an error

550 "REJECTED - Bad HELO - Host impersonating

It is when you do not get a HELO message for incoming SMTP connections. Simply login to your server via WHM as root & access option Service Configuration » Exim Configuration Manager. Find for Require HELO before MAIL & set it to Off. Click on Save & try to send/receive emails. It should start working.
