OTRS block content or link in ticket

[rvwmgk]

Is there any way to block content or, even better, hyperlinks in a ticket?

Sometimes we get viruses. Example:

[no worries, email addresses and hyperlinks changed for confidentiality and safety purpose]

Hello!

New message, please read http://example.com/feelings.php

steven.name@hotmail.tld.


The link http://example.com/feelings.php will automatically turn into a hyperlink.

Is there any way to avoid that?

I tried the flwg in SysConfig :
- Framework -> Core::Web > Frontend::RichText
- Ticket -> Core::PostMaster > PostmasterAutoHTML2Text

But that ain't it.

email spam filters could help.

A way to have that integrated on OTRS would be to use a Output Filter (FilterContent). You'd need to develop a custom filter to strip out the <a> tags, leaving only the tag text, and this would happen before the template html is sent to the browser. Or, and perhaps easier (but more hackish), just add some jQuery to the bottom of the template to do the same thing (unwrap() may be useful).
