'localhost' as default server name

[Alex Hudson]

So,

As part of our initial configuration, we default to 'localhost' as an
initial hostname. Most people don't change it; me included :) One of my
mails bounced today because of this:

220 mail-in-01.lug.org.uk ESMTP Exim 4.63 Thu, 16 Oct 2008 14:22:37
+0000
EHLO localhost
250-mail-in-01.lug.org.uk Hello barney.alcoholicsunanimous.com
[87.194.162.201]
250-SIZE 52428800
250-PIPELINING
250 HELP
MAIL FROM: <myaddress>
250 OK
RCPT TO: <mylug>
550-HELO/EHLO must contain YOUR OWN FQDN or IP literal; localhost is MY
550-name/IP!
550 Please see RFC 2821 section 4.1.1.1

Clearly, the "EHLO localhost" isn't going down very well :) I changed my
config to my actual server name, and my mail went through fine on the
next attempt.

It's not terribly easy to change your configuration choices at the
moment - it took me a few attempts - and the installation isn't terribly
good either. Does anyone have any good ideas about how we should do
this? I'm thinking that we should probably disallow "localhost" as a
value; it's almost certainly wrong. However, I don't know if we can
automatically tell what the right value is...

Cheers,

Alex.

It has been pointed out to me that we have a web based administration
tool. I tried it. It works. It was pretty easy.

D'oh.

i do think we should disallow localhost as an option. As a check you could do a reverse lookup on yourself, however that wouldn't work in call cases (like my bongo-test.info since it is on a nat'd address).

One thought I had was:
what if we tried an smtp connection to some server and did a helo and just parsed out the response. obviously it wouldn't work in all cases, however it would work for quite a few...

thoughts?

It wouldn't have worked in my situation. The EHLO succeeded fine - it
didn't give me a 5xx response until I got down to DATA.

I'm not sure it's worth trying to do that anyway, tbh - it's more
effort, and the information from the remote SMTP server is going to get
sent back in the bounce anyway.

Cheers,

Alex.

Dumbo here,

Can we not do a disconnect after a set time say 2 minutes?

Perhaps I am ignorant of why this will not fly, but what about gethostname() ?
