我已经通过名为“eblast-bounceback@mydomain.com”的 cpanel 设置了一个转发器，该转发器通过管道连接到跑步者（即，查找有关通过 rails 接收电子邮件的任何教程）。这部分工作得很好 - 我可以告诉脚本正在运行，因为我已将其设置为使用记录器。我遇到的问题是能够在退回电子邮件中找到我的自定义标题“X-Subscriber-Id:”。有没有办法访问原始电子邮件数据，这样我就可以进行正则表达式搜索，还是必须以更复杂的方式进行？
另一方面，如果我收到退回邮件，自动从数据库中删除电子邮件是否明智，或者我需要采取一些额外的步骤来避免恶意意图？
编辑：发布代码...
def receive(email)
# email.body doesn't work...how do I search for this? I know it's in the email...
account = /X\-Subscriber\-Id: (.*)/.match(email.body)[1].split("|") rescue nil
# If we've found the account info
logger.info "Nil?: #{account.nil?}"
if !account.nil?
id, private_id = account[0].to_i, account[1]
if @subscriber = Subscriber.find_by_id(id)
@subscriber.update_attribute(:bouncebacks, @subscriber.bouncebacks.to_i + 1)
logger.info "Faulty Account: #{@subscriber.email}"
end
else
# This is where we email the admin in case of failure to find an account (manual removal from database)
# This section is incomplete at this time
@from = "My Site <admin@mysite.com>"
@recipients = "admin@mysite.com"
@subject = "Bounceback could not be processed"
#@body = email.body -- What do I put here to simply re-send the email?
end
end
