I do not need a solution (just sharing information)
So, as an example, whenever I request a quote from one of our venders the quote file they send me contains their website and gets quarantined even though it’s not actually a .com file, it just happens to contain the website in it’s filename. So, I figured I would convert the wildcard match list over to a RegEx match, since it actually contains appropriate characters for specifying that a file name should end with .com. The issue that I’ve ran into with this is case sensitivity. There’s no way to disable case sensitivity in regular expressions, at least when filtering by attachment name. This means going through to each of my regular expressions and manually making them case insensitive. So… I have to convert “.*.COM$” into “.*.[cC][oO][mM]$”. That should work, however it’s clunky and there should be other ways to make something this simple function.
Ideally, we should have a way to specify flags for regular expressions. Baring that, the ability to make attachment name content filtering rules case insensitive when filtering with regular expressions would suffice.
Any other ideas for a workaround?
