Hi Bastian,
I did read that debug readme and saw the following:
>> If you can't use a test email address, please anonymize email addresses
and host names consistently. Replace each letter by "A", each digit by "D"
so that the helpers can still recognize syntactical errors.
...and is why I replaced the e-mail address and host IP addresses. The from
address for this particular message was and is the same for all messages as
this server only sends mail from one internal application. However, the to
addresses are parents, staff, and other people I didn't want to identify.
As for the statement that is tagged to all of our outgoing mail. I
apologize for that being included.
I wasn't sure whether the other debug readme recommendations were needed
but I have the postfinger output below:
