Hi Guys,

I want to store the mail being sent by thunderbird over smtp.
I have modified suricata-5.0.2/build/etc/suricata/suricata.yaml file by enabling filestore and setting filestore dir. Have also enabled smtp. Created the files.rules file. And provided the path to magic-file.

Have configured iptables as:

iptables -t mangle -F
iptables -t nat -F PREROUTING
iptables -F
iptables -A INPUT -j NFQUEUE --queue-num 12
iptables -A OUTPUT -j NFQUEUE --queue-num 12

To start suricata I am doing `./build/bin/suricata -q 12`

The mentioned files can be found here:
suricata-5.0.2/build/etc/suricata/suricata.yaml -> https://paste.debian.net/1131243/
suricata-5.0.2/build/var/lib/suricata/rules/files.rules -> https://paste.debian.net/1131244/

I am getting alerts about the smtp transfer in fast.log but the email is not getting stored. What am I missing here ?
