Helo command rejected: need fully-qualified hostname

vyvr 5 lat temu 0
I'm running Ajenti V on Ubuntu 14.04. I'm using Rainloop as a webmail client for mail. However, when sending emails to some addresses, it returns either "Helo command rejected: need fully-qualified hostname" or "550 Access denied - Invalid HELO name (See RFC2821 4.1.1.1)" and cannot deliver mail.
