Subject [jira] Commented: (JAMES-746) Reverse DNS Lookup Fails for Virtual Accounts
Date Mon, 18 Dec 2006 18:58:22 GMT
    [ http://issues.apache.org/jira/browse/JAMES-746?page=comments#action_12459427 ] 
Ant Kutschera commented on JAMES-746:

Here is a typical bounce:

Hi. This is the James mail server at rm-201-29.serve.com.
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.  Below
I include the list of recipients and the reason why I was unable to deliver
your message.

421-:  (DNS:NR)  http://postmaster.info.aol.com/errors/421dnsnr.html

The original message is attached.

The mail server name "rm-201-29.serve.com" is rubbish, because I dont own that domain, its
the name given to the server by the web hosting company that own the server. The domain that
the user sending the email from is maxant.co.uk. This domain has rDNS set up fine. I have
the same problem if other customers from other domains use the mail server, for example dragonflyjane.com.

In the james logs, it shows that it is helo ing with the serve.com name, not the domain that
belongs to the user sending the mail. So that is why I suspect there is an issue.

> My server runs multiple domains. I use the JDBC Virtual Host mailet. Everything normally
works fine, but if the user sends email to AOL or other picky domains, the mails bounce, and
it complains rDNS is not set correctly. Searching on sites like www.dnsstuff.com I am sure
that the reverse DNS is configured properly. It seems that AOL looks at the server name given
in the protocol, as opposed to the "from" address, and does a  reverse lookup and compares
to that name. But that name is taken from the server name, not the virtual account name, so
at best I can get one domain to work if I give the server the same name as that one domain.
> James should be putting the domain name from the users account into the protocol, not
the server name, if it truly supports virtual hosting.
