I know,I think, I'll just ssh -X into seviorpc at work, open upfirefox, connect to my webmail and send it from there......
Whoops! I forgot about the stupidest bug in firefox.
If it detects a local instance, instead of redirecting the graphics of a remote instance, it just opens up a another local window which means I can't just attach that file on my remote machine after all.
The crazy thing is that the firefox devs must have tried REALLY HARD to implement this bug. I have no idea why they thought it was a good idea.
