# - .procmailrc file for use with Deerfield's RelayFax as a Windows client
# and HylaFAX as the fax server
# - faxes should be directed to the user where this .procmailrc file is placed
# - faxes may also be sent manually by attaching a tif or ps file to an e-mail
# with the fax number being the subject line (if there's no attachment, then
# it will fax the message text without the FAXPASSWORD line

# We strip double quotes (") from strings because they foul up sh - or
# escaped they appear escaped on the faxcover, and we strip ampersands (@) 
# from FAXDESTINATION because they foul up the 'sendfax -d' option syntax.
# Sadly, RelayFax client isn't moron-proof, i.e. the user can submit
# destination information including ``", "'' in the string, which is quite 
# impossible to handle perfectly.

# uncomment these two if you want [verbose] logging
# VERBOSE=yes
# LOGFILE=procmail.log
