blocks|key|1538085|text|如果您接受用户输入的姓名和电子邮件，那么除非您非常小心地验证或转义姓名和电子邮件，否则只需连接字符串就可以得到一个无效的From标头。这里有一个安全的方法：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1538086|require+'mail'
address+=+Mail::Address.new+email+#+ex:+"john@example.com"
address.display_name+=+name.dup+++#+ex:+"John+Doe"

If you are taking user input for name and email, then unless you very carefully validate or escape the name and email, you can end up with an invalid From header by simply concatenating strings. Here is a safe way:

<pre><code>require 'mail'
address = Mail::Address.new email # ex: "john@example.com"
address.display_name = name.dup # ex: "John Doe"
# Set the From or Reply-To header to the following:
address.format # returns "John Doe &lt;john@example.com&gt;"
</code></pre>

within Rails 2.3.3 a bug within the ActionMailer was introduced. You can see the ticket over here <a href="https://rails.lighthouseapp.com/projects/8994/tickets/2340" rel="nofollow noreferrer" title="Ticket 2340">Ticket #2340</a>. It's resolved in 2-3-stable and master so it will be fixed in 3.x and 2.3.6. 

For fixing the problem within 2.3.* you can use the code provided within the ticket comments: 

<pre><code>module ActionMailer
 class Base
 def perform_delivery_smtp(mail)
 destinations = mail.destinations
 mail.ready_to_send
 sender = (mail['return-path'] &amp;&amp; mail['return-path'].spec) || Array(mail.from).first

 smtp = Net::SMTP.new(smtp_settings[:address], smtp_settings[:port])
 smtp.enable_starttls_auto if smtp_settings[:enable_starttls_auto] &amp;&amp; smtp.respond_to?(:enable_starttls_auto)
 smtp.start(smtp_settings[:domain], smtp_settings[:user_name], smtp_settings[:password],
 smtp_settings[:authentication]) do |smtp|
 smtp.sendmail(mail.encoded, sender, destinations)

The version I like to use of this is 

<pre><code>%`"#{account.full_name}" &lt;#{account.email}&gt;`

` &lt;&lt; are backticks.

<h2>Update</h2>

You could also change that to

<pre><code>%|"#{account.full_name}" &lt;#{account.email}&gt;|
%\"#{account.full_name}" &lt;#{account.email}&gt;\
%^"#{account.full_name}" &lt;#{account.email}&gt;^

blocks|key|1322640|text|另一个令人恼火的方面，至少对于新的AR格式，是记住'default‘是在类级别调用的。引用仅限实例的例程会导致它在您尝试使用它时静默地失败并给出：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1322641|+NoMethodError:+undefined+method+`new_post'+for+Notifier:Class|code-block|syntax|javascript|1322642|以下是我最终使用的内容：|1322643|def+self.named_email(name,email)+"\"#{name}\"+<#{email}>"+end

Another irritating aspect, at least with the new AR format, is to remember that 'default' is called on the class level. Referencing routines that are instance-only causes it to silently fail and give when you try to use it:

<pre><code> NoMethodError: undefined method `new_post' for Notifier:Class
</code></pre>

Here's what I ended up using:

<pre><code>def self.named_email(name,email) "\"#{name}\" &lt;#{email}&gt;" end
default :from =&gt; named_email(user.name, user.email)

Since <a href="https://github.com/rails/rails/commit/3a8dbe1746b3279504152ff319e64ea49464e4cd" rel="nofollow noreferrer">Rails 6.1</a> there is a new convenient helper method on <code>ActionMailer::Base</code>:
<pre class="lang-rb prettyprint-override"><code>ActionMailer::Base.email_address_with_name(&quot;test@test.com&quot;, &quot;John Test with Quotes &lt;'&quot;)
=&gt; &quot;\&quot;John Test with Quotes &lt;'\&quot; &lt;test@test.com&gt;&quot;
</code></pre>
Inside a Mailer, it is accessible without the class-name:
<pre class="lang-rb prettyprint-override"><code>mail to: email_address_with_name(user.email, user.name), ...
</code></pre>
Under the hood it uses the Mail::Address like in the top answer.

Is there a way to specify email AND name for sender and recipient info when using ActionMailer? 

Typically you'd do: 

<pre><code>@recipients = "#{user.email}"
@from = "info@mycompany.com"
@subject = "Hi"
@content_type = "text/html"
</code></pre>

But, I want to specify name as well-- <code>MyCompany &lt;info@mycompany.com&gt;</code>, <code>John Doe &lt;john.doe@mycompany&gt;</code>. 

Is there a way to do that?

Rails ActionMailer - format sender and recipient name/email address

在使用ActionMailer时，有没有办法为发件人和收件人信息指定电子邮件和名称？通常你会这样做：@recipients = "#{user.email}"@from = "info@mycompany.com"@subject = "Hi"@content_type = "text/html"但是，我还想指定名称-- MyCompany <info@mycompa
