kazé<p>I have a <a href="https://mastodon.social/tags/SysAdmin" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>SysAdmin</span></a> question: is it okay to use a local, loopback-only SMTP server (<a href="https://mastodon.social/tags/mailutils" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>mailutils</span></a> + <a href="https://mastodon.social/tags/postfix" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>postfix</span></a>) to allow a local web app to send mails directly? Without any login/passwd?</p><p>This works fine:<br> echo [boty] | mail -s [subject] [dest]</p><p>But I can’t make it work from my app (<a href="https://mastodon.social/tags/ApacheAnswer" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ApacheAnswer</span></a>), even though it does have an unauthenticated mode for SMTP. What am I missing?</p>
