wpMandrill

There is a conflict with the wpMandrill plugin. If you want to use RBE, but still use Mandrill to send out email, follow these instructions:

WP-SpamShield Anti-Spam

If you are using RBE in Inbound Mode, Mandrill's webhook will fail to post back a response to the server:
https://wordpress.org/support/topic/reply-by-email-not-working-with-mandrill#post-7806333

At this time, if you want to use RBE in Inbound Mode, you'll have to wp-spamshield. This section will be updated if there is a workaround.

If you've connected successfully, but still haven't seen your post, RBE comes equipped with a debug log.

You can view this log by navigating to /wp-content/bp-rbe-debug.log on your server.

Note down any errors you find and either post a new issue publicly or contact me privately here.

Here are some things to try:

(1) Does your site generate enough traffic?

Read this FAQ for more info.

(2) Did GMail mark your reply as spam?

If you're using GMail, see if GMail marked your reply email as spam. Login to GMail with the credentials you use in RBE and check the "Spam" folder.

If your reply email is in there, then that's the reason your reply was not posted onto the site.

(3) Are you on a shared host?

If you're on a shared host, you will not have the most optimal performance.

You should use Inbound Mode.
