Not exactly. By default, Mailman expects that the MTA uses a plus, and
not a minus, but it shouldn't be hard-coded. Qmail, for example,
defaults to using a minus as a delimiter; are you saying VERP can't be
done with qmail, either?

This doesn't make any sense. As long as the various lists and
list-extensions are in the alias file, and the VERP address is properly
constructed as an extension of a list address, the mail should get
delivered to Mailman. Something may need to be tweaked, but I can't
believe it's not *possible*.

I mean nothing outgoing, including comfirmation messages, are VERPed. As
I understand it, VERP_DELIVERY_INTERVAL should only be set to 1 if you
want *every* email to be VERPed, not just the confirmations.

Yes, I truly do.

Unabashedly littering the information superhighway with detritus like
this for over 15 years now.
