It worked well, there was however a humorous moment: I was testing with my own shell script
that simply emailed me directly to my postfix gateway, my exchange server and mua understood the
uuencoded attachment so once it started working I modified the script to send to our fax service.

Well they didn't understand uuencode so the attachment, a single page tiff, got faxed as 23 pages
of binary :) I used mutt with a redirection to a specific muttrc which understands mime encoding
which should work everywhere...

Thanks for the help, you've made an office full of people happy...
