        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 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…

                              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.
