      @marcelloc:

      What is broken on mailscanner? I'm pushing some fixes to packages on 2.2

      Does the reporting (Notices to System Administrators) works ?
      I have to manually modify the Mailscanner.conf

      Send Notices = yes
      Notices Include Full Headers = yes
      Hide Incoming Work Dir in Notices = no
      Notice Signature = – \nMailScanner\nEmail Virus Scanner\nwww.mailscanner.info
      Notices From =                                    <–------
      Notices To =                                        <–------
      Local Postmaster = Postmaster              <–------

      Giacomo

      A bit late but, better now than never. ;)

      I fixed (workaround) this by creating a file in

      /usr/pbi/mailscanner-amd64/etc/MailScanner/conf.d/my.conf

      and add

      Notices From = mailscanner@mydoamin.tld
      Notices To = admin@mydoamin.tld

      And restart mailscanner, from now on you will get email notification from infected files that have been blocked.

      This file also can used to add any extra config which otherwise will be ignored/overwritten in the Mailscanner.conf (eg. Max Spam Check Size etc.).

      Another problem I've noticed is that Org name (eg. pfSense in this case) is not correctly inherited to bayes_ignore_header at:

      Services: MailScanner > AntiSpam (Tab) > spam.assassin.prefs.conf

      bayes_ignore_header pfSense-MailScanner

      the X- is missing here and should look like instead:

      bayes_ignore_header **X-**pfSense-MailScanner

      This needs to be fixed in:

      /usr/local/pkg/mailscanner.inc

      and edit line 494 like:

      $replacement[]="bayes_ignore_header X-".($mailscanner['orgname']!=""?$mailscanner['orgname']:"Pfsense")."-MailScanner";

      So bayes can ignore those headers and don't waste tokens for that.

        I think there is a typo in the file /usr/local/pkg/mailscanner.conf.template

        39 Incoming Work User = postix
40 Incoming Work Group = postix
47 Quarantine User = postifx

        I also think that these two lines do not work, because when I put the values in the web interface, in the config lines left blank.

        307 Notices From = ${$notice_from}
308 Notices To = ${$notice_to}

        P.S. i have pfSense 2.1.5 and mailscanner 0.2.11

          Hi!

          Mailscanner blocks the content of messages and replace its contents for unknown reasons.

            Hi,

            I am in no way an expert here but I can see this entry in your log:

            Message 09C0521EADE.A9E2B from x.x.x.x (remoteuser) to mydomain is too big for spam checks (644494 > 200000 bytes)

            That is 0.2 megabytes.

            Have you changed the maximum email message size?  Without looking at my setup and If I remember correctly you can change this value in Postfix and Mailscanner.

              It looks like your internal mailhost using the same name as the pfSense/Postfix relay, you better change this. Nothing critical…

                    Hi

                    It's confirmed : Mailscanner + pfSense 2.2.x = NOT LOVE. It's broken: https://redmine.pfsense.org/issues/4508

                    It's not working dccifd module: /usr/pbi/mailscanner-amd64/local/etc/rc.d/dccifd: WARNING: /usr/local/dcc is not a directory.

                      It's related to pbi. Once 2.3 is out it will work again.
                      For now, just a pbi remove and pkg install will workaround this issue just like I've suggested on postifx.

                        For now, just a pbi remove and pkg install will workaround this issue just like I've suggested on postifx.

                        For people still struggling with this package:

                        
pbi_delete mailscanner-4.84.6-amd64
rm -r -f /usr/pbi/bin/libexec/mailscanner
rm -r -f /usr/local/etc/mailscanner
rm -r -f /var/spool/MailScanner
pkg install mailscanner
y

                        edit /usr/local/pkg/mailscanner.inc (line 39)

                        $pf_version=substr(trim(file_get_contents("/etc/version")),0,3);
//if ($pf_version == "2.1" || $pf_version == "2.2") {
//	define('MAILSCANNER_PREFIX', '/usr/pbi/mailscanner-' . php_uname("m"));
//	if ($pf_version == "2.1")
//		define('MAILSCANNER_LOCALBASE', MAILSCANNER_PREFIX);
//	else
//		define('MAILSCANNER_LOCALBASE', MAILSCANNER_PREFIX . '/local');
//} else {
	define('MAILSCANNER_PREFIX', '/usr/local');
	define('MAILSCANNER_LOCALBASE', '/usr/local');
//}

                        This makes MailScanner start and run, further testing needed of general functionality…

                          It's related to pbi. Once 2.3 is out it will work again.

                                  Hi Marcelloc, i have postfix and mailscanner running on pfsense 2.4.4-p1, i got the following warnings:

                                  MailScanner[64731]: Clamd::ERROR:: UNKNOWN CLAMD RETURN ./lstat() failed: Permission denied. ERROR :: /var/spool/MailScanner/incoming/64731

                                  Permissions looks fine, i did chown -R postfix:postfix /var/spool/MailScanner/incoming/, also chmod -R 6666 to the same folder.

                                  Runas user on MailScanner.conf and clamd.conf is postfix.

                                  Also mailscanner logs display syntax errors:

                                  Mar 6 16:09:51 pfsense2 MailScanner[56749]: Syntax error(s) in configuration file:
