Postie allows you to blog via e-mail, including many advanced features not found in WordPress's default post by e-mail feature.
This plugin is very flexible, has good security measures but doesn't force them on you, and gives a lot of needed control over the attached images and videos you can post. Unfortunately, all forms of scheduling through the code produce unpredictable results. It also causes Next Scripts: Social Medial Auto-Posting to not work automatically for posts create by email.
Seems this plugin is now under very active development and no sort of release cycle; Thus I've been updating this plugin on an almost daily basis, more bugs than fixes it seems.
articles sent via email are auto-publishing even though this option is not set in the options.
Plugin has never been able to filter out my email footer correctly either.
