It seems, Yahoo still has some troubles in delivering mails at the groups. Sometimes they appear delayed, and sometimes the delivery runs into timeouts.
As workaround we may use the webinterface (though I prefer the mail functions):
To create a new topic use:
https://groups.yahoo.com/neo/groups/PolySix/conversations/newtopic
To answer an existing posting, use the function "reply via web post" at the bottom of the mails:
