First of all thank you to Howie and Len.
Our system has the ability to send email via 3 methods:
1. Static
-no dynamic content (no parsing of message)
-use IMS POST to POST messages to recipient's email server
2. Dynamic
-use dynamic content (using cfx_imsmail tag) to parse headers for
dynamic
content and CFLOOP to create the personalized content (incredibly slow
<8,000 messages per hour)
-use IMS POST to POST messages to recipient's email server
3. Direct
-use dynamic content (our proprietary cf code to make .msg and .mail
files
and spread them across our 3 clustered servers)
-we developed this, because it was a quick way to make dynamic
emails
faster than the cfx_imsmail tag. we can create and send upwards of 350,000
10-20k messages per hour with completely dynamic/personalized content with
tracking urls for open ratios and click ratios, etc. cfx_imsmail tag (2.2
at the time) just could not do what we needed it to do quick enough.
-use IMS POST to POST messages to recipient's email server
What we did not do is set the HostName in our 'Direct' method properly. It
was hardcoded to the primary server HostName, but then showing the IP
address for the machine in the cluster that actually POSTs the mail. When
comparing the IP with the HostName that was hardcoded is where we having
been running into issues. We have now updated the code to insert the
HostName of the actual server the message is being POSTed from.
My question is in the use of MX records with the POSTing method of sending
email. If the receiving organization does a lookup comparing the IP and
HostName in the header, they will find the name and IP match. Where does
the MX record for this come in? Are they looking for the actual MX record
for the root domain? For the sending server or the named sender's email
address? Or, for the specific server that is POSTing the email? I would
think the first version, but I have been wrong before (and funny... will be
again too). We use specific servers for POSTing email only and not as fully
qualified send and receive email servers.
Thoughts? Help?

Your server is saying:
ehlo 101markweb03
and the other server wants it in the form of
ehlo 101markweb03.domain.com
You can either set up the RDNS in your DNS server (this is what iMS uses
when sending EHLO) or you can add that parameter to your
cfx_imsmail calls or download the latest post server and configurator and
set the host name. If you don't want to upgrade then you
can put the host name into the registry manually:
hklm\\software\on-line data\infusionmailserver\post\
Create a reg_sz called "HostName" and set it to whatever you want.
You'll need to restart the post service for this to take affect.
Regards,
Howie
