Almost no one is looking for random strings in random headers, since headers are (somewhat) structured data. Could you share with us what string you are looking and why you don't know up front which header field you need to use to look for it?

They can can choose from a lot of predefined headerlines and insert text to find. After that they choose a respective action. To cover all cases we had a choosable option "complete header" to find a string in every headerline without knowing the specific line. This is done easily in procmail: :0 H * ^*searchstring i agree that an option like this is needless and it was a mistake to offer it. If this is not achievable in sieve, we have to remove this search-option. May be we replace by a kind of custom-headerline.> > Kind regards, > Tom > >Thanks, Hajo

If there any only a few, then that might be used an an extra argument in the discussion on removing the option altogether. Especially when you are able to manually replace the existing uses with a construct that sieve *does* support (f.i. someone uses this because wasn't able to determine which header name was actually needed, which is easier when you actually filtered a few messages).
