Please help me to solve a problem.
I'm using Zimbra web interface and attaching file *.asc (this file contains PGP encrypted message)
The file is attached as Content-Type: text/plain; name=filename.tde.asc
but I need it to be attached as Content-Type: application/octet-stream
(I need this because email is sent to automatic parsing system, and it can't read this file attached as text/plain)
how can I do that?
