Hi

Just 'upgraded' from 2.x on Fc4 to 3.1.0

de-installed old and did a clean install of 3.1.0 from the fc4 rpm.

it does not install an executable at /usr/bin/spamc since it is a perl based app.

so the script would not work.

d.

u can you use the perl cpan shell to install the uptodate SpamAssasin or just use the

/usr/bin/spamassassin

insted of the

/usr/bin/spamc

make sure the path is right.

let me know if you need any help.

K.

The clean install of 3.1 does not install any binaries as it is a perl module.

so there is no /usr/bin entries.

d.

Hi,

just did a test with FC4 without using the FC4's RPM;s just using the cpan shell,

Code: Select all

perl -MCPAN -e shell

install MD5 LWP MIME::Base64 Mail::Internet Archive::Tar Archive::Zip IO::Wrap IO::Stringy Unix::Syslog MIME::Base64 MIME::Words MIME::Head MIME::Body MIME::Entity MIME::Parser Net::SMTP Net::DNS Net::Ping Net::Server Net::Server::PreForkSimple Convert::TNEF Convert::UUlib MIME::Decoder::Base64 MIME::Decoder::Binary MIME::Decoder::Gzip64 MIME::Decoder::NBit MIME::Decoder::QuotedPrint MIME::Decoder::UU Time::HiRes Digest::SHA1 Digest::Nilsimsa Getopt::Long File::Copy Bit::Vector Date::Calc Mail::SpamAssassin



it works like a charm....

Now I have found that the system was upgraded with YUM
and to get 3.1 only the perl version was taken hence no binaries.

installing from RPM pbone net picked up the 3.1.0 fc4 and that comes with the perl stuff so the binaries are there.

currently using procmail it works; once client traffic drops will do via content filtering.

tks
d.

great !

unfortunately it didn't work
(am using acspamfilter instead of spamfilter

Feb 16 20:23:44 satwise-ac pipe[5641]: fatal: pipe_comand: execvp /usr/local/bin/acspamfilter: No such file or directory

but there is
> ls /usr/local/bin/spamfilter -l
-rwxr-xr-x 1 acspamfilter 511 74 Feb 16 20:00 /usr/local/bin/acspamfilter

and i changed master.cf
##rje##
##smtp inet n - n - - smtpd
smtp inet n - n - - smtpd
-o content_filter=acspamfilter:dummy
##rje end##
....
##rje##
acspamfilter unix - n n - - pipe
flags=Rq user=acspamfilter argv=/usr/local/bin/acspamfilter -f ${sender} -- ${recipient}
##rjeend##


comments?...

try this

Code: Select all

chown acspamfilter:root /usr/local/bin/acspamfilter

will try when system quiet (never)
]but the filter is run as that user so that shouldn't matter surely?
d

the user does matter, if not he cant reat the file. so you will get the error saying file not found.

Here's the UpdatedVer of the Script that will Quarantine SPAM email to a defrant email accout.
