I am using 1Shoppingcart.com to send digital products to opt-in
customers. One program I have offers emails M-F (health and wellness).
4:5 participants are not receiving Welcome Message or Monday's email,
yet are receiving Tuesdays. These are HTML, newsletter template...ran
spam assasin 3.1 and received "message is html without html
content-Type" on welcome and Monday's email, but not Tuesdays.
1shoppingcart.com says to not worry about this.
In the absence of an actual sample we just have to guess.
It sounds like they are generating headers that lie about the content
type, and are relying on the user's mail client to Do The Right Thing.
We've seen this a lot before, especially on newsletter-type mailings.
If your headers claim multipart/alternative, then you need both plain-text
and HTML body parts that contain the same essential content - be
considerate of your handicapped correspondents. This may be under your
control, if you can include both plain-text and HTML versions of your
content.
If you're only sending HTML, then having a multipart/alternative or
text/plain message type is incorrect. This may or may not be under your
control - either you explicitly set an option for "plain text", "HTML", or
"both", or the program tries to figure out what you're doing
automatically. If the former, make sure you're selecting the right option.
If the latter, whoever wrote the software needs to fix that bug.
Does your template include something saying "Content-Type:" ?
I searched Spamassasin's test site for more information, message is not
listed.
Help?
If you can post a sample message with all headers intact on a webserver
somewhere and send us the URL, we could give better advice.
Your provider telling you to "not worry about it" is them dropping the
ball. Either you aren't setting your content type properly for what you're
actually sending, in which case it's a training issue, or their system is
lying about what's actually in the message, in which case they have a bug
they need to fix.
