sending mails using james was blocked by Anti Spam http://spamblock.outblaze.com

[Alice K <al...@hotmail.com>]

Hi,

I used the latest James to send out emails from java web application. It 
works very well. However, EMail from my mailserver was refused by Anti Spam. 
Reason is DSS-HELO found.

Here is the explanation note received. I would apprecate very much if anyone 
can take a look at it to see what wrong with it.

Thanks a lot.

Alice

Explanatory Note :


Hello

Your IP has been blocked because it sent mail to us using a suspicious HELO 
string.

HELO is an SMTP command with which one mailserver identifies itself to 
another.

Some spammers, in order to forge headers, issue forged HELOs like HELO
mail.com, HELO yahoo.com etc. However, actual mail from mail.com or 
yahoo.com will not have such a HELO string - it comes with a quite different 
HELO.

If an IP sends us mail with suspect HELOs like this, it gets blocked till 
such time as this is fixed.

Please have your mail systems admin resolve this issue and let me know when 
this is resolved.

regards
postmaster

Alice,

I've recently seen any number of variations on this theme, here are some tips which may or may not help..

Your server should issue EHLO or HELO followed by its host.domain name, possibly the name is simply wrong it looks like you are sending "mailserver" which may just be the host part, but perhaps you just changed that in this mail.

Otherwise the remote mailer is trying to do a DNS lookup, it could be either doing a lookup on the hostname and getting a different IP, or a reverse lookup on your IP address and not getting your correct hostname, or one of those is failing completely.

I would set the prefered hostname for your machine at the top of the <servernames> section and not use auto-detect for servernames, this means you will have to add "localhost" by hand.

Then check the NS lookup for this hostname, and the reverse lookup for the IP of your machine.

If you are running through a NAT firewall you may have to assign a hostname to the firewall and a reverse DNS entry for that, even worse you may have to assign the firewall's hostname to your server's <servernames>.

Try telnetting into the server which rejected your mail on port 25 and issue a HELO or EHLO command for the hostname you expect to be using, see what the response is.
