Mailscanner + spamassassin + clamav package

andrew0401

Fetchmail is running on another box (Ubuntu) and forwards to the pfsense box running the scanner.

Just had a complete freeze of the scanner and had to rebuild from scratch - the install hung at

PCRE-8.21-1.TBZ (Extracting) after I hit enter it continued.

Not sure that my theory of using another machine to run fetchmail is going to work. It appears that the SMTP traffic (going direct to pfsense scanner) is being processed correctly, but POP3 traffic collected by the other machine using fetchmail and then forwarded to the scanner is not being scanned for spam - my guess is that because it is on the same network it assumes it is whitelisted? Or am I more confused than usual?

@marcelloc:

On this current version, you are able only to see amount of messages on quarantine.

status -> postfix queue

the mailscanner package use native sqlite2 databases while mailscanner use sqlite3 to store quarantine data.

There is a way to enable sqlite3 on mailscanner, but I'll need to rewrite a lot to update it to sqlite3 only.

Maybe next version I include a tab for quarantine.

Today I use only reject, attach or subject action for spam on my system.

If you really need this, you can make a donation to mailscanner package so I can write it for you.

I would be interested in a quarantine tab with a release and whitelist function for valid messages that get caught in the filter.
please PM me with what you feel an appropriate donation would be

UPDATE: After speaking to Marcello over PM, he has agreed to work on adding a quarantine tab to the mailscanner. I have made a donation to this effort and encourage anyone else that is interested to please donate as well. I feel a the addition of the quarantine / white list function adds a lot of value and functionality. Right now I have many clients using hosted solutions for spam filtering but would much prefer to have the it on my pfsense installations

Hi Marcello

Do you have any updates on SASL authentication and if/when it may be included in this great package?

I would love to migrate our existing SMTP solution over to this but the lack of authentication is the only thing stopping me.

Cheers,

James

smtp auth is from postfix package, I've posted an answer there :)

I tools like you need to select another language report.

reports//languages.conf

should be

reports/some_language/languages.conf

capitangiaco

thanks now it works!
compliments for the great job!!!!

(I needed to set 'no' and again 'disarm' "Removing/Logging dangerous or potentially offensive content" directives to make it works).

I tried to re-install the system (I am using I386) from scratch, and I wrote some notes that may be of help:

sa-spamd and clamd start
manually added:
clamav_clamd_enable="YES"
clamav_freshclam_enable="YES"
spamd_enable="YES"
to /etc/rc.conf/local

Deliver from postfix to mailscanner, manually added:
header_checks = regexp:/usr/local/etc/postfix/header_checks to /usr/local/etc/postfix/main.cf
created the /usr/local/etc/postfix/header_checks with '/^Received:/ HOLD' inside
restarted with postfix reload
I didn't find the options that make this work from the web configurator <– help please! :)

Cannot lock /var/spool/MailScanner/incoming/Locks/clamavBusy.lock, No such file or directory
chown -R postfix /var/spool/MailScanner/incoming/Locks.

This is a very usefull pkg, thanks to Marcello for the great work!

I use all these options with no file hacking.

Did you installed postfix pfsense package to work with mailscanner?

Installed first postfix forward and then mailscanner-dev

header checks are on services -> postfix forwarder -> access lists

Hello all
I have installed Posfix Forwarder and the mailscanner + spamassassin + clamav package. Postfix is working wonderfully but I think I must have somthing wrong in my configuration with mailscanner. In Postfix I have the 3rd party option enabled / The mode is set to auto. I have the mailscanner package enabled as well as the CLAMAV and spam assassin options enabled. But when I run the GFI Security Test EVERYTHING get through.

When I look at the process list for mailscanner I see
55735 ?? S 0:05.39 MailScanner: waiting for messages (perl5.12.4)
56936 ?? S 0:04.45 MailScanner: waiting for messages (perl5.12.4)
59478 ?? S 0:04.08 MailScanner: waiting for messages (perl5.12.4)
60031 ?? S 0:04.05 MailScanner: waiting for messages (perl5.12.4)

when I run tail -f /var/log/maillog |grep -i mailscanner

I get nothing?

if I restart mailscanner I get this

any help is apperciated

marcelloc

check if you can find /^from:/ HOLD on view configuration -> header check

If not, change mailscanner Message Hold mode on antispam tab to manual and include the above line on access lists -> header

That worked
thank you marcello

tanhosy

I have a question (can be a bit stupid!). Can MailScanner + Postfix run in transparent mode?.
The reason is I have a pfsense box with 4 interfaces + 01 mail server stand alone. I want to run pfsense without intervention on the mail server.

marcelloc

Well, I did no transparent mode on this package but if you know how to do it on postfix I can merge this on next release.

Not yet but sometime in the future ;)

I noticed a 'strange' thing, incoming attachments files become zipped, cool feature, but who is the author of this ?
