django - Sparkpost suppression error and mail stops sending -


i using sparkpost 1 of django website send mails users. had update on site sending mails users.

however few of users have deleted gmail id gmail , understand mails cannot sent ids.

however problem facing in django, sparkpost stops sending mails users once single mail fails because of this.

error message this:

message generation rejected code: 1902 description: recipient address suppressed due system policy

that specific error ...suppressed due system policy sparkpost saying decided not send particular recipient address because appears on global suppression list. can read here basically, no-one should send email addresses on list sparkpost rejects mail them avoid later reputation damage.

that issue alone shouldn't stop mail flowing though. here few other options check out have effect:

  • what error sparkpost produce other failing messages?
  • has account been suspended? log in check.
  • does api key have correct privileges?

as aside, ask question on sparkpost community slack team.

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...

Why does math.random(999999999999) returns 1 in Lua? -

i tried: print(math.random(999999999999)) , has printed 1 . also math.random() includes 999999999999 printing same thing. examples: print(math.random(1.999999999999)) » 1 print(math.random(1999999999999)) » 1 for k,v in next,{math.random(999999999999), math.random(1999999999999), math.random(2.999999999999)} print(v) end » 1 local n = math.random(999999999999) print(n==1) » true then think understood (if know lua of course). can explain me? @edits: the lua version i'm using 5.2. i tried print(math.random(-999999999999)) , printed 111711452 . looks worked positive number. this problem surely because math.random treats input arguments passed in lua 5.1 and/or 5.2. [mathlib.c] 1 : as may know in c , standard int can represent values -2,147,483,648 2,147,483,647 . adding +1 2,147,483,647 , in use-case, overflow , wrap around value giving -2,147,483,648 . end result negative since you're multiplying positive negative number. ther...
