Deleting or returning mail - doesn't work?

[Dio]

It doesn't look like the API functions ReturnMail or DeleteMail (with or without the 2nd argument) do anything, is this intended to prevent addons from removing mail?

e.g. ReturnMail(GetNextMailId()) or DeleteMail(GetNextMailId())

I found that the mailbox needs to be open and the mail has to have been read. try adding

RequestReadMail(mailId)

before your code. The other issue I found is you need to wait for a response back from the event

EVENT_MAIL_NUM_UNREAD_CHANGED

before it takes effect

[Teli]

try this code you have to queue them all up first. Then when you process the code it fires the first delete event. The event will keep triggering mailOpen.ProcessDelQueue() until it runs out of entries in the table.

function mailOpen.QueueDelete(mailId,forceDelete)
    table.insert(delQueue,{['mailId']=mailId,['forceDelete']=forceDelete})
end
function mailOpen.ProcessDelQueue()
    if delQueue[1].mailId ~= nil then
        --d(delQueue[1].mailId)
        DeleteMail(delQueue[1].mailId,delQueue[1].forceDelete)
        table.remove(delQueue,1)
    end
end
 
 
function mailOpen.Test()
    for k, v in pairs(mailOpen.mailInfo) do
            if v.unread then RequestReadMail(v.mailId) end
            mailOpen.QueueDelete(v.mailId,false)
    end
    mailOpen.ProcessDelQueue()
end
 
--EVENT_MAIL_REMOVED
function mailOpen.MailRemoved(eventCode, mailId)
    mailOpen.ProcessDelQueue()
    d('mail deleted')
end
