MailScanner: A long gap in a name is often used to hide part of it (Arve nr. 10616237 .pdf)

A lot of combination with position of "." symbol cause "false positive" blocking. Where to switch it off?

Is there a way to make messages blocked as bad content quarantined and releaseable ? Great also to send the notification to user that he has a blocked message.

Unable to release some blocked messages

Hi

Messages blocked as a "bad content" can't be released. Seems they are not stored. Where to find these settings? Would be great to notify user about blocked message by a content and store it. Please help.
