RE: Dangerous in-line attachments

Naïve question - I tend to stick with the stable versions (5.3.4-3 now...)  - anything I should be worried about by migrating to 5.4.3-1 ?

It works for me with MailScanner 5.4.3-1

Add `bit.ly` to /etc/MailScanner/phishing.bad.sites.custom
run `sudo ms-update-phishing`
run `sudo systemctl restart mailscanner`
