I just upgraded from ISPConfig 2.2.19 to 2.2.21. There appears to be a change in the way MailScan is working. MailScan is now "defanging" the style of any emails I receive that have an embeded style. If I view the source of the email I can see new tags around the style section that say DEFANGED_STYLE. This prevents the style from being applied. MailScan up through ISPConfig 2.2.19 would "defang" the extensions of file attachments but it did not alter tags within emails...at least not style tags. Was a change made to /root/ispconfig/isp/conf/html-trap.rc.master ? I have disabled MailScan in ISPConfig for now to prevent style defanging.
