I'm looking for a Windows E-mail client with the following abilities:
1. Can send and receive messages in Unicode format (more specifically, UTF-8).
2. Can search for a string in an entire message (body and header). It must be able to search in the entire message using a single option, i.e. it must have an option saying "Search in entire message". It isn't enough to be able to combine two options saying "Search header" and "Search body" to have the same result.
3. Can forward messages so that the "From" line shows the original sender rather than the forwarder.
The last version of Eudora from Qualcomm can do 2 and 3, but not 1. The Mozilla version of Eudora can't do 2.
I usually use kmail using Linux, which can do all three, but I'm looking for a Windows program. I've tried the Windows port, but found it unacceptably slow under Windows 7 64-bit.
