OK, thanks much I'm getting nearly there but the customer is now requesting a couple more items that are stumping me with mailman.
First, they don't want their list members to have to remember passwords or even be prompted to enter a password when signing up, basically they want them to be able to sign up and sign off with no other options. Is there a way to properly set mailman up to function in this manner?
Also, they've given me a huge (>250,000) list of members of their list previously and they want me to insert this into the list since they are moving service providers (the previous one started spamming their list and they can't have that type of junk going on with their members) to import. Mailman has had an "internal error" each time so far when I've tried to upload the list of addresses. What is the proper way of inserting such high numbers of previous subscribers? I am thinking that I'll probably have to divide the list up into smaller chunks, but don't even know what the max size that mailman will accept.
Thanks again!
