Topic: Spamassassin How-to for E-smith 6.0

[Arjan Vroege]

Is there a good how-to for Spamassassin for E-smith 6?
Is there a good version available for e-smith 6?

Thanks

Greetz,

Arjan

[John Lewis]

I'm also very interested in this.  This is the only thing holding me back from moving forward on testing 6.0...

Hi
Go to www.dungog.net He has an e-mail filter which can also use Spamassin. A small charge but Stephens software is good & will run directly with SME 5.6/6

...or just use the spamassassin contrib from contribs.org for 5.6; seems to work fine on my installation of 6.0beta.

[Arjan Vroege]

it seems that it's working with the contrib of contribs.org
The only problem is that he have not installed python.2.2., because he missed lib.... . But everything seems to work fine.

Any suggestings?

Following is an email sent to me by Darrell May and posted here with his permission.  It details the steps to activating Spamassassin on SME 6b3.  If I find time, I'll formalize it into a howto:

Hello Greg/James,

I've just taken a look at your e-smith-spamassassin-0.0.2-1jp2.55.noarch.rpm.  As you may be aware, SME6.0B3 includes components for Spamassassin that are installed however simply not enabled/configured.  One intriguing rpm is sortspam-1.0.0-01.i386.rpm

I have taken a look at how easy it is to enable system wide SA under
SME6.0B3.  Here is all that is required:

To enable/start SA: (e-smith-spamassassin-0.0.2-1jp2.55.noarch.rpm does this already)

# /sbin/e-smith/config set spamassassin service status enabled
# ln -s /etc/rc.d/init.d/e-smith-service /etc/rc.d/rc7.d/S85spamassassin # /etc/rc.d/init.d/spamassassin start

To enable Qmail to use SA (from SME6.0B3 sortspam-1.0.0-01.i386.rpm):

/sbin/e-smith/config setprop smtpfront-qmail InternalInterfacesFilter
"/var/qmail/bin/qmail-spamc"
/sbin/e-smith/config setprop smtpfront-qmail ExternalInterfacesFilter
"/var/qmail/bin/qmail-spamc"
/sbin/e-smith/signal-event email-update

This now sets the SA daemon /usr/bin/spamd scanning all
incoming/outgoing mail at the SMTP level.  This is done via the
templated /etc/e-smith/templates/etc/tcprules/tcp.smtp/00qmailqueue
found in e-smith-mailfront-1.2.0-01.  Instead of invoking
/var/qmail/bin/qmail-queue it now invokes /var/qmail/bin/qmail-spamc as
follows:

SMTP > Mailfront > qmail-spamc > qmail-queue

In addition the above works well with RAV/BitDefender AntiVirus scanning
and would be easy to back port to >=SME 5.5 simply by installing the
latest e-smith-mailfront-1.2.0-01 rpm.

In my personal case, I no longer use IMAP.  I'm on a slow satellite
connection and IMAP is just too painful.  So the whole
IMAP/procmail/user-manager is of no value to me anymore.  I'm now
POP3/Outlook.

Moving SA to a system wide SMTP scanner has many benefits:

1) spam scanning may be performed both inbound and outbound
2) the HUGE overhead of per user procmail/sa is reduced to one running
system daemon
3) non-IMAP/POP3 users can benefit from SA tagging.

So, are you interested in updating your e-smith-spamassassin rpm to
incorporate the above suggestions?  Do you require any assistance?

Comments are welcomed.

Can smtpfront-qmail have multiple InternalInterfacesFilter's. I notice that Amavis uses this same setup. ie would Amavis and Spamassassin be able to coexist using this setup? I currently have Amavis setup but if I ran this db command would it hose my A/V setup?

Use ExternalInterfacesFilter for spamassassin in your case.

I used to have /usr/bin/qmail-queue.amavis set as my ExternalInterfacesFilter but after running the command /sbin/e-smith/config setprop smtpfront-qmail ExternalInterfacesFilter it has changed it from /usr/bin/qmail-queue.amavis to /var/qmail/bin/qmail-spamc So it appears that you can either amavis OR qmail-spamc but not both. Is this correct or am I doing something wrong.

[Greg Zartman]

Yes, I see your point.  I just noticed that there is a difference between my SME serverlink box and my SME 6b3 development machine with respect to this subject.

I'm not sure where the GPL line here is, so I better defer this to Mitel for comment.  Post your question on the devinfo mailing list.  Simply ask how the External and Internal smtpfront-qmail filters are used and how to propagate their settings to mailfront.

Good luck.

Did any one go and ask this question. If not I will, but I can't guarantee I will understand  the answer. I have gone and read the mailfront docs but this is a level above my current Linux understanding

I am very interested in getting amavis and spam assassin working together as system level scanners on sme6b3.

What is the best way if I choose not to use spamassassin anymore (after I user Greg's instruction to enable it)

[Michael Herger]

I've successfully installed SA on my test machine. It's correctly tagging my mails. But I still have two questions:

- I've read in the spamd documentation that I can use personal user_prefs using the --user-config parameter. I've put one in /home/e-smith/files/user/admin/.spamassassin/ but it's ignored. Where do I have to put them?

- What's the easiest/standard way to filter junk automatically into the junk-folder? As I've understood the current configuration only tags mails but does not move them.

Thanks in advance for any hint! Regards,

Michael

For completeness here, this thread appears to have the answer on how to get both Spamassassin & Clamavis working together on v6.0b3

http://www.e-smith.org/bboard//read.php?f=1&i=34384&t=34382

You need to edit your "amavis.conf" and change line 56 ( or there abouts) to read

qmail-queue = /var/qmail/bin/qmail-spamc

This will allow the message to be virus scanned then handed to SA.
