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:


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.
