今天对邮箱整理的时候在最底下找到了当时注册 riseup 邮箱的时候收到的一封统一的邮件，细细读来还是挺有意思的，特此分享出来，并对部分内容进行加粗，加注，考虑到大多数用户可能只能读懂英文，本文只包含英文部分，如果想看原始邮件内容可以在下方评论，我可以将邮件 Forward 给你一份。

=== english ===========================
Welcome to your new riseup.net email account!
We know you are busy making trouble and changing the world…（注：说实在的，第一次读到这句话的时候把我逗乐了） but can save
yourself and us a lot of trouble by reading this email.
Visit https://user.riseup.net from there, you can change your password, add
email aliases, set up email filters, change your quota, and request help.
We automatically destroy the information you gave us as part of your account
request. You should consider removing any identifying information from your
account settings, such as your name, birthday, secret question, and alternate
email. However, if you forget your password and this information is not set (or
you’ve forgotten what you stored, or the alternate email is no longer
accessible), then you will lose access to your account.
Important things to know
(1) Protect your password
The Internet is crawling with people trying to steal your email account. At some
point, you will probably receive a fraudulent email from someone pretending to
be riseup.net. These emails will claim that you must perform some action in
order to keep your account.
. Never give your password to anyone, especially someone claiming to be
. Never trust that the “From” address of an email is from who it says,
because this can be forged easily.
. Web links in email messages are often fraudulent. To be safe, you should
retype the link rather than clicking on it. Also, be careful about
misspellings, like riseupp.net instead of riseup.net
(2) Automatic deletion of messages in some folders
Messages in some folders are automatically deleted after a certain number of
. Trash: deleted after 21 days.. Spam: deleted after 7 days.. Sent: deleted after 120 days.
For many reasons, we do not provide much storage space for email. If you need
more space, consider downloading your email using a mail client or increasing
your quota by visiting https://user.riseup.net. More information on this can be
found at https://riseup.net/email.
(4) Use an email client
Although the riseup.net web-based interface does not have many features, you can
use your riseup.net email account with a feature-rich desktop application
designed specifically to handle your email.
Riseup recommends Thunderbird, a free and open source mail client:
Thunderbird will automatically configure itself correctly if you just give it
your riseup.net email address and password.
What is special about riseup.net email
Your riseup.net email account is a wonderful thing. Although we don’t provide as
much storage quota as surveillance-funded corporate email providers, riseup.net
email has many unusual features:
(1) We encrypt traffic whenever possible.
When you send email from riseup.net to another secure email provider, the email
is encrypted for its entire journey. (see https://riseup.net/starttls for more
(2) We don’t disclose your location to email recipients.
When you send email with riseup.net, your internet address (IP address) is not
embedded in the email（注：国内的邮件服务商普遍比较脑残，喜欢把发件人的 IP，邮件软件等信息放到 Headers 中，示例内容见本文末尾.). With corporate email providers, anyone who receives your
email can figure out your approximate physical location from the internet
address included in the email.
(3) We don’t log your internet address.
Our commitment is to keep as little data on you as we can. Unlike corporate
providers, we do not log internet addresses of anyone using riseup.net services,
There is no such thing as free email. Services like gmail, hotmail, and yahoo
make their money from surveillance: they build a profile on your behavior and
your desires and then bombard you with advertising specifically targeted to you.
（注：其实很多服务也是这样的道理。他们看似提供免费的服务，实则是以 “你” 作为代价的。记得看到过一个比较经典的评论：如果他们不是在向你出售他们的服务，就是在出售你.)
Riseup.net is different. This service is a labor of love by activists like you
committed to building movement-run and secure alternative infrastructure.
The riseup.net email service takes a lot of time and money to keep running, and
is funded entirely by small donations from its users. Please do your part and
