So i was going down the rabbit hole of why every outgoing message for a certain 500+ member list is being VERPed, which lead to RoadRunner/Spectrum complaining about too many connections, and I tried to look at the verp configuration:
(venv) *mailman@mail*:*~*$ mailman conf |grep verp [mta] verp_confirm_format: $address+$cookie [mta] verp_confirm_regexp: ^(.*<)?(?P<addr>[^+]+?)\+(?P<cookie>[^@]+)@.*$ [mta] verp_confirmations: yes [mta] verp_delimiter: + [mta] verp_delivery_interval: 1 [mta] verp_format: ${bounces}+${local}=${domain} [mta] verp_owner_notifications: yes [mta] verp_personalized_deliveries: yes [mta] verp_probe_format: $bounces+$token@$domain [mta] verp_probe_regexp: ^(?P<bounces>[^+]+?)\+(?P<token>[^@]+)@.*$ [mta] verp_probes: no [mta] verp_regexp: ^(?P<bounces>[^+]+?)\+(?P<local>[^=]+)=(?P<domain>[^@]+)@.*$
I'm quite confused about why verp_delivery_interval is 1 instead of the default 0, and why verp_probes is no. I did make sure that "Personalize" was set to None. I tried to override them in mm/var/etc/mailman.cfg, but it seems to be having no effect, even after restarting mailman. Is this not the correct syntax: [mta] verp_delivery_interval: 0 verp_probes: yes
Is something else overriding my mailman.cfg setting?
Are you sure mm/var/etc/mailman.cfg is the actual mailman.cfg in use.
mailman info will tell you.
I do have a list:member:regular:footer but it doesn't have any user information in it, so that shouldn't cause it to do the messages individually, should it?
No, the footer has nothin to do with it. I suspect you may have
installed following
<https://docs.mailman3.org/en/latest/install/virtualenv.html> in which
case yoor mailman.cfg is /etc/mailman3/mailman.cfg and I suspect that
file has verp_delivery_interval: 1
