SMTP Error (550): Failed to set sender

Postby juddy » Sat Nov 04, 2017 7:18 pm

Hello,

I've searched all possible articles and sites, but nothing has worked out. Basically, I can receive e-mails, but whenever I try to send an e-mail I get this error

Code: Select all

SMTP Error (550): Failed to set sender "xxxx@xxx.org" (Access denied - Invalid HELO name (See RFC2821 4.1.3)).


I followed this post https://forum.vestacp.com/viewtopic.php?f=12&t=15345 and the error disappeared. However, I still wasn't able to receive my e-mails.

My host is set to: fastlisting.org
Smtp.log:

Code: Select all

CentOS 7

I can't send e-mails to others. I can only send emails to myself(Perhaps, the localhost).

Nope.

Yes I can receive e-mails from others.

Yes. It's working just fine. I run my own web server on the machine.
