Our installation of RT looses its line breaks in emails when viewed in outlook
mail clients. Can anyone give me some hints on how to fix this?
Presumably you’re talking about mail entered via the web ui. You might
want to look at what sort of line wrapping the text entry box is doing or
possibly using one of the many perl Text reflowing modules to wrap at
some number of cols. iirc, there’s even a routine to do this somewhere
in RT1’s libraries.
