Thanks to all for the plethora of information about VERP and how it is used by the MTAs and Mailman. Just for clarification, I don't have a list of 250,000 subscribers, just a site that has a total of 250,000 subscribers over 500+ lists. I think the largest is about 40,000.
So, if all I want to do (which was my original question) is to VERP confirmations, I only have to add this to Postfix: default_verp_delimiters = += verp_delimiter_filter = -+=x and this to mm_cfgy.py: VERP_CONFIRMATIONS = Yes All other VERP setting are whatever is the default in Defaults.py. VERPing the confirmations seems to work as expectedc and I assume that there is not much of a burden on the server without VERPing every message or even VERPing a sample of messages. Thanks again for the good information.
