I am using OG Mailinglist 7.x-1.1-alpha2. We have been using this module for years now. We have a new user who is attempting to send emails to a couple of our lists which are the email part of Organic Groups which the module OG Mailinglist turns into listservs. This new user is sending basic emails with no inline images or attachments and is getting each email sent rejected with the rejection response saying the emails could not be read properly.
Usually when this happens this is because of a bug with the library used to decode the emails in that the library malfunctions when you have both an attachment and an inline image in the body of the email, but the person having the issue is just sending text emails.
We would appreciate any insight.
