[SOLVED] Case insensitive regex for Postmaster filter?

[EXG133]

I'm using several postmaster filters that are case insensitive like this:

.*[Ss][Aa][Pp]\s?[Gg][Uu][Ii]\s?740

Which works fine. However now I've received a request to filter for quite a few long strings. If I make them case insensitive this way the regex is too long for the Postmaster filter box

I tried

.*(?i)string
.*(?i:string)
.*string/i

But that doesn't work. Anyone have a way to make the entire regex case insensitive?

The second one - (?i:string) - should work

[EXG133]

Well...

Both .*(?i)string and .*(?i:string) work. I must have accidentally selected a different email header at an early point while testing my regex. I was trying to set Queue to 'closed' which of course OTRS can't so it looked like my filter didn't hit ...

Thanks for confirming reneeb and maybe this will help someone else!
