 post-via-email-results-in-no-title-for-the-post-title/ 5.4: Sending Post
 via Email Results in “(no title)” for the post title] on the forums:

 > Once a week I send an email to my blog to go into a category I have set
 for them. Anyway, starting with 5.4, the post titles were all “(no
 title)”. I did a comparison between wp-mail.php in 5.4 and 5.3. At line
 216 changed:
 > {{{
 > if ( '' === $post_title ) {
 >       $post_title = $subject;
 > }
 > }}}
 > To:
 > {{{
 > if ( '' == $post_title ) {
 >       $post_title = $subject;
 > }
 > }}}
 > Now, the posts get the title from the email’s subject once again. Not
 sure if this is a bug or emails need to be structured differently now.
