無法發送大宗電子郵件時使用任何寶石在軌道上

我曾經使用過寶石，在那裏我安排超過500封郵件在特定時間執行，但它不會。但如果我發送15或20封電子郵件，。我每次都在輸出文件中獲得以下內容。無法發送大宗電子郵件時使用任何寶石在軌道上

那麼請問有什麼可以解決售後服務這個錯誤，讓電子郵件被髮送到500人，如果任何電子郵件是錯了，我可能會在另一個日誌文件輸出..... ...所以請幫助........... ??

批量提取用戶，然後嘗試發送郵件。

郵包

def birthday_email 
    date = Date.today 
    Employee.where("status = ? AND strftime('%d/%m', date_of_birth) = ?", "Active" , date.strftime('%d/%m')).where("age > 21").find_in_batches do |group| 
     sleep(5) 
     group.each { |emp| mail(to: emp.email, subject: 'Birthday Wishes') } 
    end 

end

耙

EmployeeMailer.birthday_email.deliver!
