HELO Checking [Re: What to include...]

the lookup is on mail.winserver.com, and a FAIL result
should cause a reject.

Personally, I am getting more confused as this discussion progresses.


The machine name for our Sendmail server is Server1.yellowhead.com, and
after discovering that it was not using this fully qualified name on the
outbound HELO, it was corrected. However, this is not the name of any of
the domains that it acts as mail server for. It is not possible to use the
correct name for each domain on the HELO, because all but one of these
domains are pseudo names. The only record you will find for
Server1.yellowhead.com is an "A" record. There are no "MX" records or
"TXT"
records.

What is the point of checking anything on the fully qualified domain name?
The Host name (Server1) has no meaning: only the domain name
(yellowhead.com) portion will produce any meaningfull results as far as
SPF
is concerned.

That is what I am "naturally" thinking too.   It seems to make more sense.

You see I am not sure how other SMTP MTA software works,  but our server its
gets host name based on the binded IP.  We don't currently have a "fixed"
name that you assign which is something I am considering for our next
release.  But the last thing I want is so joe put put in a fixed FDQN and it
be wrong when he puts the server on a different machine or IP.   So its not
cut and dry.

Anyway, since our product is a multi-server product,  many of our sysops
will prepare A records for each server:

    ftp.winserver.com
    www.winserver.com
    mail.winserver.com
    telnet.winserver.com


etc. So any one of the above can round-robin and return as the host name for
the SMTP MTA sender session.
