CentOS 8 Stream (fully updated), ISPConfig 3.2.3 server (used the CentOS 8 ISPConfig Perfect Server method..) i come from an older version of RHEL, so maybe something has changed that i'm not aware of... I was poking around in the Maildir folders (cur/new/tmp) under /var/vmail and noticed that the actual email files are have single quotes wrapped around their names when I do an "ls -l" within the directory. an "ls" shows the same thing. going back to my home directory, same thing, but only on files that have spaces in them. i assume it's the non-alphnum characters that are causing the issue. i unaliased LS just in case there was some forced setting there causing it, but still the same thing. when i start typing in one of these names without the single quote, and press the TAB key to autocomplete the name, it finds it and escapes the non-alphanum characters, but no single quotes. Can someone shed some light on this behavior? obviously, it's intentional, and probably useful, but this must be a newer feature - i didn't notice it in CentOS 7, though I didn't play around in there long before switching to 8 instead. Curious, thanks.
