I am a new owner of a listserv and we are working with a particular vendor (MYVENDOR) that would like to have the ability for anyone with an email of "@myvendor.com" to post to the listserv we just set up. This would allow someone from their company with that email address to post without having to maintain (add/remove) individual email addresses. Can someone tell me if this is possible? And if so, how to accomplish this? Thanks in advance. -- Duane Theleman, PMP <https://www.pmi.org/pmp/>
