Question #164820 on mailman in Ubuntu changed: https://answers.launchpad.net/ubuntu/+source/mailman/+question/164820 Status: Open => Answered Mark Sapiro proposed the following answer: Note that this answer is for GNU Mailman in general and not specifically for Ubuntu, but see the FAQs at <http://wiki.list.org/x/boA9> and <http://wiki.list.org/x/TIA9>. If these do not answer your question, consider that the probable answer is that the post to embeddedmaillist@domain is probably from a non-member of maillistmember@domain.org and is being discarded by maillistmember@domain.org for that reason. -- You received this question notification because you are a member of Mailman Coders, which is an answer contact for mailman in Ubuntu.
