Question

My email arrives with SpamAssassin rules HELO_LH_HOME

Asked by: WEBuilder

I am using jmail 4.5 with classic ASP to send email. When it arrives, SpamAssassin tags it as spam. One of the rules it "breaks" is:
3.2 HELO_LH_HOME          
I can't figure out what this rule is, so I don't know how to correct it within jmail.

Any ideas?

This is the spamassassin rule :-
header HELO_LH_HOME X-Spam-Relays-Untrusted =~ /^[^\]]+ helo=\S+\.(?:home|lan) /i

Can you give some more information on how the email is setup.
What server does jmail send its mail to?
Is this directly to your mail server or does it go via another one?
A copy of the full headers of a received mail would really help.

Generally what this rule means is that the mail comes from an untrusted source (which most emails are) and that the mail server which sent the mail advertised its name as "home" or "lan". These short names are not correct over the internet as a full name should be given. Its fine for local machines but in this case these machines should be trusted anyway so this rule wont match.

The message header is below.

I am currently sending the test message to myself from a virtual private server, but eventually this classic ASP program will be using Jmail to send out confirmation messages to anyone that uses the website.

So where is spamassassin installed?
It looks from the headers like it is installed on the same box which is sending the emails. I thought it would be on your mail server so I am a little confused.

However I think the fix is to have a look at the spamassassin configuration and the 'trusted networks' section. You need to make sure that the IP address sending the mail is listed as a trusted network.
Once you have jmail implemented things will change anyway so I would not be too concerned about that particular rule matching at the moment as once jmail is implemented it will likely disappear.

Spam assassin is on my hosting company's servers, which are different than my client's server. My host is "hsphere.cc" and my client is "asktherabbi.org".

I probably can configure my own copy of SpamAssassin, but I don't want to do that, because none of the visitors to the website will do that. I need to get this to send out mail that is not considered SPAM by adjusting parameters in jmail - or whatever is necessary on the client's computer. I would assume that this would be either configuration changes in the mail server, or changes in the jmail program. For example, I just added the line

Mailer.Maildomain = "asktherabbi.org"  

but this did not change the results. This was based on the only reference to "HELO" in the jmail manual.

I don't understand your comment about jmail. It has been installed and it is working (sending out email) now. Did I imply that it wasn't "implemented"?

 

by: grbladesPosted on 2008-09-21 at 02:19:04ID: 22533800

So can you tell me where the mail is being sent from and to.
You have said the spamassassin is on your hosting companies servers which is fine.
Where does the clients server come into it. Is this the server using jmail to send the mail?

The only received header in the headers you posted is this one :-
Received: from localhost by spamassassin.hsphere.cc with SpamAssassin (version 3.2.5);
This is saying that the mail was generated on the local machine and once scanned it was not passed onto any other mail server.
It looks like some headers are being removed somewhere.

> but eventually this classic ASP program will be using Jmail to send out confirmation messages
Sorry I took this to mean you were not using jmail at the moment.

In my profile I have a test@ email address listed. You could get a test email sent to that address and then post back here when it has been sent. I will then be able to see exactly what is going on.

 

by: WEBuilderPosted on 2008-09-21 at 03:15:02ID: 22533899

Two tests have been sent to your test email address.

 

by: grbladesPosted on 2008-09-21 at 03:43:13ID: 22533945

Here are the headers of the mail I received. Jmail is sending the mail to a mail server and then that mail server is sending the mail onto me.
It is the mail server itself which has the configuration problem. It is calling itself CT3270.home which is not a valid full domain name and is what is causing the HELO_LH_HOME rule to match. It should be changed so that it advertises itself as 'host00962.ve.carpathiahost.net' instead.

Thank you. I have contacted the host to determine how to do this on the new server. If it corrects the problem, I'll return to award the points. If not, then I'll be back with addidtional information.

Thank you for your help so far.
