Code review requested: imap message broker

<p>Hello! I&#39;ve been learning Go for the past few weeks now, and finally released my very first project. It&#39;d be awesome to get a code review! </p> <p>Here is my project <a href="https://github.com/mikaa123/imapmq" rel="nofollow">https://github.com/mikaa123/imapmq</a></p> <p>Thanks!</p> <hr/>**评论：**<br/><br/>Ainar-G: <pre><blockquote> <p>Pwd</p> </blockquote> <p>&#34;Pwd&#34; usually means &#34;Print Working Directory&#34;. I&#39;d go with &#34;Pass&#34; or &#34;Password&#34;, but that&#39;s nitpicking.</p> <blockquote> <p>Logout()</p> </blockquote> <p>Usually such methods called close, but I don&#39;t know the specifics of IMAPMQ, so I might be wrong.</p> <p><a href="https://github.com/mikaa123/imapmq/blob/master/worker.go#L77" rel="nofollow">https://github.com/mikaa123/imapmq/blob/master/worker.go#L77</a></p> <p>Error ignored.

Close would probably be more explicit.</p> <blockquote> <p>Error ignored. Why?</p> </blockquote> <p>In this case it&#39;s ignored because no error can happen at that place. If it does, then it&#39;s a bug in my code and I&#39;d rather have it break loudly. I guess I could catch the error and Panic if it happens, but since I control the input, I&#39;m confident that it will never be called.</p></pre>FIuffyRabbit: <pre><p>Or passwd. Some security audits will complain at the usage of <em>password</em>. </p></pre>misokol123: <pre><p>Good to know. I ended-up using that.</p></pre>
