# Sample regexp lookup "table".
#
# Format is /regexp/flags or /regexp/flags!/regexp/flags
# where regexp is a regular expression as found in regexp(5), and flags are
#   i: toggle ignore case (REG_ICASE - default is to ignore case)
#   x: toggle extended expression (REG_EXTENDED - default is extended)
#   m: toggle multiline mode (REG_NEWLINE - default is non-multiline mode)
#
# In order for a line to match, the first regexp must match, and the
# second (if present) must not match.  The first matching line wins,
# terminating processing of the ruleset.

# Disallow sender-specified routing. This is a must if you relay mail
