OT: HELO setting in Sendmail

[Mike Pepe <la...@doki-doki.net>]

Hi folks, this is a bit off topic, but I figured someone here may have 
an inkling as to what I could do.

Some mail servers are now rejecting my email:

     (reason: 550 Don't like your HELO/EHLO. Hostname must contain a dot.)

I checked and sure enough, the HELO just spits out the hostname, not the 
fqdn.

Is there a setting in Sendmail to override what it spits out? I've been 
googling and can't seem to find anything that indicates that it can be done.

It's sendmail 8.13.1-3 on a FC4 box.

thanks

-Mike

MC
define(`confDOMAIN_NAME', `my.external.host.name')

is probably what you need

or for cf hacking

Djmy.external.host.name

You probably mean broken resolver implementations. but these should 
either be fixed or abandoned. It's been years that the BSD 
implementation is freely available. if your vendor/distributor manages 
to give you a broken one, then complain, upgrade or migrate.

ahem...
        http://www.postfix.org/postconf.5.html#myhostname
says "The default is to use the fully-qualified domain name from 
gethostname()."

That's an oxymoron.

There are no "well-behaved tools" which do not accept a FQDN for a hostname.

Quite the opposite: those tools which do not accept an FQDN for a 
hostname are _broken_, and therefore are not well-behaved.

Sun's installation configuration tool, for example.

Because then well-behaved tools will be messed up?

I'd help, but I only know how to do this in Postfix.

why not set your hostname to an fqdn value?
