Thanks for your help. I'm going to try to create the .mlf files with a script, first I have to understand its content.
# Mercury List Membership File for list 'hidden@novelltstephenson.com'
# Mercury Mail Transport System, Copyright David Harris, 1993-2003
#
# This file contains mailing list subscriber records in tab-delimited
# format. Provided you are careful, you can edit it using a text editor
# but you must make sure that the editor actually inserts TAB characters
# when you press the TAB key.
#
# The fields within each subscriber record appear in this order:
#
# Status Single character in [A,N,D,V,X]
# Address RFC822-reduced e-mail address
# Name RFC822 Ctext/Qtext component for name
# Flags 16 printable ASCII characters
# Postings Postings since inception (8-digit, 0-padded)
# SubsDate Subscription date, YYMMDDHHMMSS
# SubmDate Last submission date
# VacDate Vacation date
# Password Password for user
# Comment
#
# The first line in the file must remain exactly as it appears above, but
# all the remaining comments in this block can be deleted if you wish.
# The record format is not tolerant of errors. Dates must be exactly
# 12 characters in length, using 0-padding as required. White space is
# significant and preserved in all cases. The last line of this file must
# always end with a CR/LF.
#
# We recommend that you use the Mercury user interface to maintain this
# file unless you are very sure of what you 're doing.
Again, James Haley's BuildMLF makes this a lot easier.
