This is just a FYI.
Mailing lists work by, surprise, e-mail addresses. Therefore, if you post
from a different e-mail address than the one you used to subscribe to, the
mailing list software doesn't recognize that you are subscribed and will not
forward your message to the list.
So, you either need to always post to the list using the same e-mail
address, or you need to subscribe to the list for each individual e-mail
address you intend to use.
