my config is not checking/rejecting an email with eicar attachement

what should i enable in rspamd service to make clamav work?

has no one a suggestion?

Hello,
I have setup a mailgw on opnsense latest release according to https://docs.opnsense.org/manual/how-tos/mailgateway.html
sending an email with an attached file which includes the eicar virus pattern is not detected by my opnsense fw.

tail -f /var/log/postfix/latest.log will show me the incoming email.
tail -f /var/log/rspamd/rspamd.log show that rspamd is invoked, spf and dkim checks.

But there is no activation of clamav. no logfile entry of the check.
after enabling in /usr/local/etc/clamav-milter.conf
LogSyslog yes
LogFile /tmp/clamav-milter.log

restart clamv service
also no log entry at all.

It looks like that clamav will be not activated in this milter chain.

Hi,
just replaced my firewall from endian to opnsense. everything worked so far in my esxi environment.
I added a new debian vm. an ip4 dhcp was assigend, but this vm can not access the apt mirror (ip6).
Lookes like internal vm can not acces via ip6.
How can I solve it.

regards.

Thanx,
just disabled it.

Hello,

I use postfix and get the following warning:
Warning   postfix/smtpd   warning: permit_tls_clientcerts is requested, but "smtpd_tls_ask_ccert = no"

How can I set via Web UI this parameter in /usr/local/etc/postfix/main.cf ?
I can not set it directly, because webUI will overwrite it.
It would be neat, if Web UI would allow to place extra params in a text field

Hi,
I have one public IP/domain name. I want to access multiple backend http(s) servers (upstreams).
I have it working with one backend http server (int ip 10.0.0.5).
https://myhost.mydom.com will show content of internal webserver

now I want to have 2 seperate internal webservers (int ip 10.0.0.5 and 10.0.0.6):
access from internet:
https://myhost.mydom.com/server1
https://myhost.mydom.com/server2

how to achive this?
I want to get rid of the server1 and server2 url part, which will reach the internal web servers.

Any ideas, working examples?

regards
rudi
