Hi All,
Running OI9.3.2 and having problems with sending emails using CDOMail..
Return value from CDOMail.. Access denied - Invalid HELO name (See RFC2821 4.1.1.1)
After further investigation, I noticed not the full server name is being passed to create the HELO.
However, if I try manually sending the instructions and greet with “EHLO SERVERNAME.CO.ZA” I get a 250 OK after the MAIL FROM. See below outputs from putty.
No FQDN:
EHLO SERVERNAME
250-serv22.registerdomain.co.za Hello SERVERNAME [41.162.51.42]
MAIL FROM:[email protected]
550 Access denied - Invalid HELO name (See RFC2821 4.1.1.1)
With FQDN:
EHLO SERVERNAME.CO.ZA
250 serv22.registerdomain.co.za Hello SERVERNAME.CO.ZA [41.162.51.42]
MAIL FROM:[email protected]
250 OK
Is there a field in the config where the hostname can be stipulated as the full FQDN, when using CDOMail or any other setup configuration I can change in OI, or the email account, or email server?
Please help!!!!
I can be contacted at [email protected]
Thank you.

Is this pasted or typed, as, it shows HELO and you testing has EHLO

Hi Barry,
Sorry, it was typed… both should be EHLO.
