First, sorry to bother the list with this question – but I have been
searching for hours trying to figure this out and haven’t found it.
Maybe one of you can help me…
I am interested in setting up either DKIM or DomainKeys to work with my
QMT. I’m not sure I care which one as I think that either will help me
with Yahoo.
Have you checked out Jake's video
(http://videos.qmailtoaster.com/video/how-to-setup-dkim-on-qmail.html)
about how to do this?
Here’s what I don’t understand. DNS for my domain is NOT performed by
the QMT, but by HostGator where the website for the domain in question
is hosted.
That is not a problem. The authoritative DNS server for a domain should
be on a separate host, not on the QMT host. Technically, it could be on
the same host, but this is not considered to be a good practice.
When I send an email with the public key in the header,
Techically, the public key isn't sent in the header. A signature is sent
in the header. The signature is unique to each message, and is created
using the message contents and the private key.
will
the receiving server authenticate with HostGator (because they are the
DNS for this domain)
Yes. The receiving server obtains the public key from HostGator, then
uses that key to verify the correctness of the message signature.
or will the authentication process happen when my
QMT and the receiving server are talking to each other during the email
transmission process?
No. Nothing happens in the smtp session regarding DK or DKIM.
To further complicate, my QMT forwards through my ISP’s email server.
Will that muddy things at all?
I don't know off hand, but I expect not. Perhaps someone else can answer
this definitively. It depends on whether or not the message headers are
included when generating/validating the signature.
I’m not sure whether the private key should be on my QMT or on
HostGator.
Private key goes on QMT, public key goes on HostGator.
The private key should *never* leave QMT, and should be kept as secure
as possible (600 permission bits).
If HostGator, they haven’t been helpful so far. I have
DomainKeys enabled for my site on HostGator, but they don’t give me
access to the public key to put that into my QMT email header.
I'm not sure what you mean by this. You should be able to maintain your
DNS text records, which is where you should put your public key.
Any help would be very much appreciated.
HTH. Do check out Jake's video. The DomainKeys page on the wiki might
help with some understanding, but that method is broken so I wouldn't
use it at this point.
