I just tried it and was able to start a PDF viewer locally, i.e. on my
system, not the one I was connected to. I just typed "!evince" at the
"ssh>" prompt.

I'm not sure how your plan will work, though,given that presumably the
attachment is on the remote computer along with the email and thus not
accessible to your local viewer.

If you save the attachment on the remote in (say) /tmp, then you could
use a local command like "!scp me at remote:/tmp/filename.pdf /tmp ;
evince /tmp/filename". Untested..
