根据 Rails API(下面的代码段),接收邮件的最佳方式是在一个守护进程中创建一个 Rails 实例,每当有新邮件到达时,MTA 就会调用该实例。
我的问题是:当新邮件到达时,您如何将数据传递给该守护进程?
=========================
Rails API 片段
To receive emails, you need to implement a public instance method called receive that takes a tmail object as its single parameter. The Action Mailer framework has a corresponding class method, which is also called receive, that accepts a raw, unprocessed email as a string, which it then turns into the tmail object and calls the receive instance method.
Example:
class Mailman < ActionMailer::Base
def receive(email)
page = Page.find_by_address(email.to.first)
page.emails.create(
:subject => email.subject, :body => email.body
)
if email.has_attachments?
for attachment in email.attachments
page.attachments.create({
:file => attachment, :description => email.subject
})
end
end
end
end
This Mailman can be the target for Postfix or other MTAs. In Rails, you would use the runner in the trivial case like this:
./script/runner 'Mailman.receive(STDIN.read)'
However, invoking Rails in the runner for each mail to be received is very resource intensive. A single instance of Rails should be run within a daemon if it is going to be utilized to process more than just a limited number of email.
