Hi Karsten,
This is just out of my curiosity. Your signature looks something different.
What does that represent?

You need to scan mails that are greater than 256MB?!
Reason I'm asking this is that sometimes email attachment(s) size may be on
the higher side, that it would easily exceed 256 MB limit.
Whoa, slow down, dude. I'm with Daniel here.
Fact is, spam even larger than 512 kB is rare. Sure, they do exist, and
this topic comes up here every now and then. However, they still are a
rare occurrence, and it is not worth the trouble raising the limit to an
arbitrarily large number.
The limit exists for two reasons. First, *really* large spam simply
doesn't exist, and mail that size just is ham. And second, scanning
really large messages will slow down SA and hog resources.
It's a trade-off. Not even scanning those rare, huge spam. Versus a
dramatically increased need for resources.
Don't think of the max size limit as which size *mail* do I get, but
which size *spam* do I see. Ham exceeding the threshold will just be
passed along un-scanned.
Really, think about it. How much spam exceeding 1 MB do you get? One a
year? How much ham? Plenty, due to creative folks tossing around huge
images?
So, set your max size limit to something sane, say 1 MB, and live with
that single spam per year sneaking through unprocessed. Sparing your
servers the load of processing all the bulk of huge messages.
Oh, and another one. Any chance, these huge messages might be Cc'ed to
more folks on your site? Awesome, so we just multiplied the resources
needed. If there are max 5 children, all fed with a piece of ham that
easily exceeds 256 MB concurrently, will your server die a slow and
horrible death of hitting swap?
IMHO, if you are ever to raise the threshold to anything above 10 MB, do
test it extensively before going into production.
Bottom line: Keep your max size limit sane. No kidding.

spamc client always returning 0/0
Hi, My SpamAssassin setup: SpamAssassin version 3.3.1 running on Perl version 5.8.8 installed on Red Hat Enterprise Linux Server release 5 (Tikanga) My problem is, the spamc client is not at all working and it is always returning 0/0. At the same time, if I use spamassassin script, it's working and is giving back spam score result. Example: # spamc -R mymailmessage.txt # spamassassin -t mailmessage.txt I believe that either some library is missing or some environment setting is missing. Also, how do I print only Content analysis details from spamassassin command-line tool by suppressing the whole mail message from being printed? Is there any option that controls this?

That indicates an error. Did you start spamd?
You can use spamc -x, to get a meaningful exit code.
Example:
# spamc -R mymailmessage.txt
# spamassassin -t mailmessage.txt
I believe that either some library is missing or some environment setting is
missing.
Nope, spamc pretty much only passes STDIN to spamd.
Also, how do I print only Content analysis details from spamassassin
command-line tool by suppressing the whole mail message from being printed?
Is there any option that controls this?
man spamc
Please DO read the docs. The -R you already used should do what you
want. In your case, it simply did not, because an error talking to spamd
occurred, and you are using the default of safe fallback. In case of
an error, the message is passed back. See -x, again.

Not possible as far as I know. SpamAssassin's idea is to be a *filter*,
which means it possibly adds to the original and never removes anything.
Correct for spamassassin, but possible with spamc. Which the OP wants to
use anyway.
See the -c, -r, -R and -y options in man spamc.
By default, spamc acts as a filter, but this behavior is configurable.

Check your logs.
spamd likely logged the failure. And btw, spamc also logs in some cases,
like refused connection attempts to spamd. You will find your previous
attempts without spamd running being logged.
Also, try something like this.
echo | spamc -x; echo $?
The first echo simulates a message. Poorly at that, but suitable for
what we're debugging here. Check the returned exit code with the list
given in the spamc man-page.
