If I set a “Mail Rate Limit” on a domain, virtualmin edits:
/etc/milter-greylist/greylist.conf
thusly:
ratelimit “domain_1723064206327109” rcpt 50 / 24h
racl blacklist from /.@cheese.com/ ratelimit “domain_1723064206327109” msg “Message quota exceeded”
racl whitelist from /.@cheese.com/
racl whitelist default
In the example my domain is limited to 50 recipients per day.
It stands to reason that somewhere there is a 37 that turns to a 38 that turns to a 39 and so on with each outbound mail.
Does anyone know where that number is (and whether I can manipulate it somehow)?
According to that greylist.conf, this looks promising:
dumpfile “/var/lib/milter-greylist/greylist.db” 600
But there is no such file and if I set a limit on a domain and then send a mail through one of its accounts, that file does not materialize. (Note that I do not have MySQL running on this instance if that is needed for this to work.)
In my example, if my domain gets to 50 mails in a day, I will know about it (either by the users of the domain complaining or perhaps by something I have setup to watch logs). As I never expect this domain to send more than 10 mails in a day, I know that something is wrong (hacked account, maybe a failing all-in-one-printer-scanner parsing some document into 1 email per page, etc) so I investigate.
Once the problem has been addressed, I would like to manually reset the milter’s counter to 0 (without waiting till the 24 hours are up) so that everyone at the domain might get back to business.
(Obviously the settings are just for an example, I do not host cheese.com and I would not limit a domain to 50 mails per day.)
