[shiva prasad <si...@gmail.com>]

Hi guyzz,
               I need info as to what exactly is the spamassasin behavior in
the following scenarios

1)   Empty mail with no subject/body (I have this treated as SPAM in my
local pc with default configuration of spamassasin0

2) Email with subject in only numbers with nobody

Regards
shiva

Please keep the thread on-list. Do reply to the list, rather than to

I see. However, we only can help you, if you have access to the box and
can control / tune the SA installation. If you cannot do this, you
should contact the vendor's support for the device.

Moreover, we can't help or suggest configuration changes, without a
sample as requested previously. At the very least the SA headers,
showing the reason why the box considers the messages to be spam.

As-is, outgoing mail FP'ing, can have a lot of reasons. Merely an empty
body is unlikely to cause it all by itself, though probably just pushed
the score over the threshold, combined with other tests hitting, too.

It depends.

Any such characteristic would only be one (tiny) part of the final
score. There are a *lot* more rules and tests SA performs, which may
impact the overall score -- both ways, positive as well as negative.

Some of the tests depend on local data, and thus are impossible to
predict just like that. And of course, it also depends on your local
configuration and score-set in effect.


I suggest you explain your issue, and why you are asking these very
specific questions.

If you do have such samples processed by SA, at least show us the full
SA headers -- or even better, put a full, raw sample message up a
pastebin, and tell us the link.
