无论何时使用rails中的gems都无法发送批量电子邮件

Question

我曾经使用过gems，我已安排超过500封邮件在特定时间执行，但它不会继续。但如果我发送15或20封电子邮件，那么它就会。我在输出文件中得到以下内容什么时候。

rake aborted!
Net::SMTPServerBusy: 452 4.5.3 Error: too many recipients

那么我怎么可能解决这个错误并让电子邮件发送给500人，如果有任何电子邮件错误，我可能会在另一个日志文件中得到输出........所以请帮助.... ....... ??

Answer 1

批量获取用户，然后尝试发送邮件。

邮件收发器

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!
