This is a performance tuning problem. You need to do a flowpath
analysis to see where your bottlenecks are and what is causing
them. Probable causes:
-- Bad choice of MTA (eg Sendmail)
-- Bad configuration of MTA (eg list posts are DNS verified upon receipt)
-- Bad name resolution support (eg no system-local DBS cache)
-- Bad RCPT TO size bundling (mailman config)

Without knowing the version of Mailman being used and a host of
other system particulars, this is impossible to answer. My best
guess however would be choice of MTA and bad MTA configuration as
the likely causes.
