How to filter incoming emails with links and words

[Hamed.nrz]

Greetings ProxMox Community,

Im kinda new to Proxmox mail gateway, had prior experience with Symantec Mail gateway, but due to some circumstances and the need of organization, I had to shift towards Proxmox and honestly it's really convenient to work with. Furthermore, I would like to see how can I define a mail filter rule that modifies every email that has link in it. To give some context, this was easily done in SMG and you could do this with just 3 clicks and quarantine all incoming emails with links attached to it, but as for Proxmox, I went through forums and searched it up, and yet to find a solution. Moreover, Is there a method that I can define Sensitive words that spammers usually use in emails to quarantine them? Any help regarding this matter will be highly appreciated. Thanks

I have seen many similar topics, but I have not received an answer. How to make a rule using text with?

On the forum send to https://cwiki.apache.org/confluence/display/spamassassin/WritingRules .

It turns out something like /\sometext\b/i = strict match, case insensitive.

Did I make the rule right?

Can you make examples in the documentation for the main cases - blocking domains with subdomains, blocking by text in the subject or body of the letter, strict and non-strict?
