I need a fully-qualified hostname

Asder · May 2, 2006

Hi!
I use Sendmail on my mailserver, but I've got a problem.
Some providers reject my email with this message:
"reason: 504 <firewall>: Helo command rejected: need fully-qualified hostname".

On an IIS server I could solve the problem with:
default SMTP virtual server -> property -> delivery -> advanced -> write the domain name on "Fully-qualified domain name".

But the question is: how can I do that on Sendmail?

Honestly I've just start to use Sendmail, and I don't know linux very well.

Thanks a lot!

This means that receiver's server fails when doing a reverse lookup on your mail server's hostname.

Is this mail server handling more than one domain?

No, just one.

Make sure this is set correctly.

Code:

define(`confDOMAIN_NAME', `[i]domain.com[/i]')dnl

Hello,

I have the same problem with some providers wihch reject my email messages with this error:
"Server Response: '504 <>: Helo command rejected: need fully-qualified hostname'".
How can i configure 'Sendmail' to send fully-qualified hostname in the HELO command?
Note: the server is handling multiple domains.

Thanx.

You use what I posted above and make the the reverse DNS to your machine translates to what you defined.
