[Mailman-Users] dumping a large list to a file

[Scott R. Every]

I have a list with upwards of 600K emails on it.  Many of the addresses on 
the list have the nomail bit set, yet when I use 'list_members' there seems 
to be no way to get only the valid emails(ie no nomail emails listed)

I have a customer who needs to split this list into X number of pieces in 
order to send different content to each piece of the list.  The problem is 
when we work from the file that 'list_members' outputs, mailman spins its 
wheels trying to deliver mail to the nomail addresses(most of which are not 
valid addresses) and it slows things way down because the mail server has 
to deal with all these bounces.

I have also tried using the dumpdb tool, but it takes upward of 8 hours to 
dump the whole db which is far too slow.

Is anyone using segmented lists with mailman?
has anyone figured out a way to get just the good email addresses out of 
the mailman db?

any help would be appreciated.

thanks
